Non-glass pH electrode InPro® 3300: An unbreakable breakthrough for the food industry.

Non-glass electrode for pH measuring systems– InPro®3300

Your benefits– Process safety: eliminate broken

glass from your process– Cost-effective: no time-consuming

grab-sample analysis– High-productivity: real-time results

support immediate decisions

INGOLDLeading Process Analytics

Raw milk delivery and storage:Continuous quality control priorto processing.

Sour cream and butter production:Direct installation supports automatic process control.

Yogurt manufacture: Directmeasurement in incubation tank avoids over-acidification.

No fear of broken glass in the medium

Our new, unbreakable non-glass InPro 3300 pH electrodesupports on-line pH control as a key element in meetingyour customers’ expectations for an affordable, safe and nutritious food. The consequences of fractured glasspH electrodes pose a much more serious threat in foodprocessing than in other industries. No matter how small,glass fragments can bring your process to a halt.

High throughput due to on-line pH control measurement

The new InPro 3300 is carefully engineered to integratewith high-throughput automated processing systems. INGOLD’s innovative on-line pH solutions eliminate costly and time-consuming grab-sample analysis, thereby improving your bottom-line.

Many traditional batch processes in the food industry have now been replaced by automated production methods employing advancedprocess control systems. The potential of these automated systems can only be fully exploited when a continuous flow of comprehensivereal-time process data is available.

Our proof of outstanding and durable quality

– Compliance with 3-A sanitary standards ensures that dairy produce, food and other micro-biologically sensitive products are protected from contamination and that all equipment surfacesare easily cleanable.

– Tested in line with EHEDG (European Hygienic Equipment Design Group) provides assurance thatequipment complies with the criteria for hygienic design as sanctioned by the European Union.

– Compliance with FDA (Food and Drug Administration): Internationally recognized approval criteriafor materials used in the manufacture of equipment for the food and pharmaceutical industries.

Our non-glass solution for pH measurement – a convincing program to optimize your process

pH transmitter pH 2100 e – State-of-the-art «Advanced Line» transmitter– Power feed for ISFET preamplifier already integrated as standard– Easy to operate– Second current output for temperature measurement– PID controller

InTrac 798 CIP retractable housing – access to electrode without process interruption– During the plant CIP cleaning cycle using highly caustic media, the ISFET electrode can, in

its retracted position inside the flushing chamber, easily be cleaned and sterilized by hot steam– The hygienic design and sterilizable flushing chamber prevent any risk of contamination– Fits most standard fittings, and is EHEDG tested

Soft drinks and juices: Continuousmonitoring of free acidity – the most important characteristic of soft drinks.
