1.3 Product Introduction
TDL 300 adopts a transceiver optical design. The remote detector will send two laser beams; the detector laser is invisible and the spotter laser is visible.
After pressing the trigger, the device will automatically begin detection and the spotter laser will begin to flash. When you release the trigger, it will stop detecting and the spotter laser will close.
The device will enter dormant mode and then standby mode after a period of no operation. When the operator presses the trigger, the TDL 300 will turn on automatically and continues detection.
Do not stare directly into the laser and to not aim the laser into other people’s eyes.
When the device is in detection status, it will display the Methane concentration on the LCD screen. If a leak is detected that exceeds the alarming threshold an alarm icon displays on the screen and an alarm sound can be heard.
Improper operation, i.e. being to far from the target or pointing the detector at a bad angle, may cause false alarms or no alarms to sound. Please move to the proper distance or angle in order to perform inspections.
The TDL 300 has environmental durability, and insignificant amounts of dust will not influence the sensitivity and detection range.
The device is powered by a lithium-ion battery and can work for 6 hours under normal conditions. Standard packaging includes two battery packs. When one battery pack is depleted, change to the other battery pack in a safe area.
• The Spotter laser is a Class 3R laser. Do NOT stare directly into the beam or point the beam into other person’s eyes.
• Do NOT aim the spotter into the sun to avoid damaging the device.
• Only charge the battery using the customized charger from ICI.

2.1 Detection Principle
The TDL 300 adopts advanced tunable diode laser absorption spectroscopy (TDLAS) technology combined with DSP digital signal processing techniques. This detection method uses wavelength scanning and tuning characteristics of semiconductor laser diodes as well as the absorption characteristics of Methane to eliminate cross interference. DSP allows digital circuits for signal generation, analysis, and processing to assist the anti-interference capability, improve stability, and produce repeatable results.
When the laser of the TDL 300 is aimed at the target gas pipeline, part of the laser beam is absorbed by leaking Methane. The laser beam returns after being scattered or hitting a barrier behind the gas. Returning light is collected by an optical lens, and received by a highly sensitive InGaAs detector. After the signal is processed, gas concentrations are displayed on the LCD screen.
Thus, the Methane detector is suitable for areas that are difficult to access such as expressways, bridge pipelines, or other places that cannot be reached. Direct access to these areas is not mandatory as an operator will know if there is a gas leak, and its concentration, if they follow the procedures laid out in this manual.
2.2 Glossary & Definitions
Detecting Laser: the laser beam sent by the handheld detector to detect gas leaks;
Spotter Laser: the visible laser beam sent by the handheld detector to assist the operator in aiming at a targeted area;
Scanning Distance: the longest working distance of the detector;
Reflection Light Fault: a fault caused when the handheld detector cannot get enough returned light because the reflective rate is low, the scanning distance it too long, or the ambient environment is not conducive to scanning, etc.
Tunable Diode Laser Absorption Spectroscopy (TDLAS): an advanced technique used for gas detection which adopts laser wavelengths and tuning characteristics;
Integral Concentration: the traditional measurement of gas detectors is the average indoor/outdoor gas concentration, the unit is ppm or %LEL. The TDL 300 measures the gas concentration along the “effective path of light transmission“ between the detector and the target reflector. Normally, the effect of high gas concentrations in small ranges is equal to low gas concentrations at a larger range. The unit is measured as a gas average concentration, i.e. PPM*m or ppm.m.
Diagram 2-2 (next page) shows two gas plumes: one at 5 m with a concentration of 100 ppm and a second gas plume at 2 m with 250 ppm. These plumes appear in the path between the detector and the background reflector and is equal to that of 100 ppm * 5 m * 2 = 250 ppm * 2 m * 1000 ppm.m.

5. Batteries are fully charged when red indicator lights turn off;
6. Remove the charger from the power socket.
• If the red charging lights continues to flash after the batteries are plugged in there is a bad connection or malfunction. Pull out the battery and plug it back into the charger or reboot the charger. If you cannot solve the issue contact the manufacturer.
• Charge in a dry and safe environment.
• Do NOT use in temperatures above 50 °C
• Remove charger from power socket when not charging.
• Only use the charger provided by ICI to charge the battery packs to avoid damage and danger.
3.4 Wavelength Calibration
In order to keep the detector working with high sensitivity follow the calibration process below:
1. Take detector out of carrying case;
2. Press trigger and On/Off button at the same time, then release the trigger after the detector achieves normal status;
3. The number that shows on the display will increase from 0 to 500, then decrease from 500 to 0; the process will last about one minute;
4. Detection can begin after by pressing the trigger after the device enters normal status.
• Laser wavelength drift is normal and will not affect the sensitivity.
• If you feel the sensitivity of the device has suffered, follow the steps above to calibrate the laser’s wavelength. ICI suggests you calibrate every half month to ensure the best sensitivity.
30 31
1. In order for the TDL 300 to detect a gas leak, three conditions must be met:
• The gas plume concentration ans size must be greater than the minimum sensitivity of the TDL 300,
• The detecting laser beam must pass through the gas, and
• The background target, i.e. building, ground, etc., has to reflect the laser beam back at equal to or greater than the detector’s requirement.
2. Turn on the detector, press the trigger, begin detection by aiming at the target area. Note: Detection begins only after the trigger is pressed. Let the laser beam pass through the gas plume and reflect the laser on the ground, a building, etc. Because the detecting laser is invisible you should use the spotter laser to line up the detector with the target. Note: the detecting laser and spotter laser are in parallel and the spotter laser is above the detecting laser. Keep the spotter laser above the target around 50 mm when detecting a gas leak.
3. Detection begins after pressing the trigger. Once a gas leak is detected the gas concentration will show on the detector’s LCD display. The detector will light up and sound an audible alarm once the gas concentration exceed the pre-set alarm threshold. The louder the sound the higher the concentration.
4. Several factors affect the concentration and size of a gas plume:
• Windy weather or high temperatures will lead to rapid diffusion of gas, decreasing the gas concentration.
• Methane’s density is lighter than air, and leaking Methane will diffuse upward causing the gas concentration to become lower with increased height from the ground.
Operators should take the above factors into consideration during inspections and make the right judgment according to their experience.
5. To determine the location of a gas leak, work the laser beam in a stable “S” pattern route back and forth to ensure the laser passes through the target area. A constant alarm sound indicates a leak, and operators should check where the sound is the loudest.
6. The TDL 300 can detect gas leaks from up to 30 m. Actual distance may vary due to target surface and environmental conditions. As the scanning distance is increased, the laser light returned will decrease. As the maximum distance is approached, a low fault alarm will sound telling you to move closer or change the scanning angle in order to continue detection. It is best to scan within 10 m to 20 m of the target.
• Experience with the TDL 300 will make aiming at the target position easier and ensure the laser beam passes through the target are.
• Windy weather or high temperatures will lead to rapid diffusion of gas. Scan against the wind
• Methane’s density is lighter than air. Scan directly over places where gas leaks are likely to occur.
• The detection beam is a cone-shape. The spot/beam width size will become larger with increased scanning distance and is around 50 cm at 30 m.
• Obstructions or variations in landscape can cause dark zones where the laser cannot scan. Change to a better angle and scan the location again.
• Strong reflection off certain types of surfaces, e.g. stainless steel, glass, polished surfaces, reflectors, etc., may give false readings. Rescan the area from a different angle.
4. Measurement Method
32 33
In order to maintain the good working condition of the TDL 300, the following maintenance should be performed as indicated:
1. Put the detector back into the carrying case, and recharge the battery to full capacity after each use to ensure battery life.
2. If needed, clean the outer surface of the device with a clean cloth.
3. No need to clean the optical lens frequently. If needed, use a dust blower to blow away dust on lens. Then, use medical gauze or an equivalent non-abrasive lens tissue with a small amount of alcohol. Avoid scratching the lens.
4. Contact a local distributor for assistance in changing or replacing accessories and parts or directly contact ICI.
5. To determine the location of a gas leak, work the laser beam in a stable “S” pattern route back and forth to ensure the laser passes through the target area. A constant alarm sound indicates a leak, and operators should check where the sound is the loudest.
6. The TDL 300 can detect gas leaks from up to 30 m. Actual distance may vary due to target surface and environmental conditions. As the scanning distance is increased, the laser light returned will decrease.
