Electrode & Sensor

Low-maintenance pH electrodes with integrated temperature sensor.

Xylem's WTW SenTix® 41-47 pH electrodes feature a durable plastic shaft and a cylindrical membrane, and are ideal for both laboratory and field use. The integrated temperature sensor ensures precise readings by compensating for temperature variations, while the gel electrolyte provides low-maintenance operation without the need for refilling.

NTC 30 kOhm, 1 m fixed cable with waterproof DIN and 4 mm banana plug

SenTix® 81, 82, 91: Precision electrodes with liquid electrolyte and built-in temperature sensors for lab pH measurement

Excellent electrolyte flow without clogging by platinum wire junction

Automatic temperature compensation with built-in temperature sensor

Optimum results thanks high quality membrane glass

SenTix® 81/82 and SenTix® 91 pH electrodes (shaft length 170 mm) with 3 mol/l KCl electrolyte are designed with an easy to clean glass shaft and platinum wire junction. The electrodes are also well-suited for difficult samples. For temperature compensation a built-in NTC 30 kOhm temperature sensor is used. For this SenTix® series different connections are available.

The SenTix® HW pH special electrode with its ground-joint diaphragm, high-quality glass shaft and 170 mm length is particularly suitable for low-ion media, emulsions and suspensions in the laboratory. The cylindrical shape of the membrane is robust and with refillable 3 mol/l KCl liquid electrolyte, the electrode offers fast response times.

The SenTix® ORP redox electrodes with their glass shaft made of high-quality membrane glass and the ceramic diaphragm are suitable for demanding measurements in the laboratory. All ORP electrodes consist of a metal electrode made of a precious metal and a reference electrode. As with all SenTix® electrodes, the reference system is silver/silver chloride.
