Memosens pH Probe

Digital Sensor.

The Memosens inductive sensor connector system transfers both energy and data without contact between electrochemical sensors and analyzers.

The integrated intelligence allows saving and evaluating sensor-related data directly in the pH/ORP sensor.

With its perfect galvanic isolation the Memosens prevents interferences, allowing straightforward and safe

measurements even with most difficult potentials. The sensors can be easily handled under adverse conditions – you can even connect them under water.

ISFET Micro pH probe (SENTRON MicroFET)

This micro electrode is made of PEEK and has a diameter of only 3 mm. The measuring part (the sensor) is built-in at the conic end of the electrode. Therefore this electrode can very good be used for measuring of very small volumes or in very small sized sample cups and in micro-titer plates.

These electrodes can be used in applications in thin high pipes (flexible) or to measure the pH in meat (stainless steel) and cheese. This electrode can be connected to one of the 2 SENTRON pH meters and are very suitable for applications in the bio-technology, food, pharmacy, etc.

The minimal liquid level for the measurement is 7-8 mm.

Length: 110 mm

Cable length: 1600 mm

ISFET Mini pH probe (SENTRON MiniFET)

ISFET IntelliProbes pH Probes

Bring non-glass pH probes to standard glass electrode pH meters, giving faster, safer and more reliable measurements. These high-tech Ion Sensitive Field Effect Transistor (ISFET) pH probes replace fragile glass electrodes with sturdy silicon sensors. The IntelliProbe series pH probes are virtually unbreakable, lightning fast and can be stored dry. The clog-resistant sensing area is easily cleaned using a simple toothbrush and requires minimal routine maintenance.

The IntelliProbes combine all developments in non-glass ISFET pH sensor technology with state-of-the-art sensor signal processing. The electronics are safely embedded in the probe and powered by a long-life replaceable battery. Intelligent signal processing converts the ISFET and temperature signals to perfectly match the glass pH electrode signal at the measurement temperature. This allows accurate, fast and reliable results, while enabling full use of the glass pH meter's automatic temperature compensation facility. Includes 'self diagnostics', auto shut-off, a low battery warning, easy one-button operation for calibration and a led for on/off function.

Thess electrodes can be connected to one of the 2 SENTRON pH meters.

Sentron-Line pH Electrode

The SentrON-LINE series of rugged, non-glass pH probes are specially designed to be built into an on-line system. The high-tech ion sensitive field effect transistor (ISFET) solid state pH probe brings the advantages of being virtually unbreakable, fast measurements and dry storage, well known in the laboratory, to industrial and process systems.
