pH & temperature sensors for demanding applications in the laboratory
Xylem's WTW SenTix® 81-87 pH glass electrodes are high-performance sensors designed for precise pH and temperature measurements in challenging lab applications.
Product Features
- Glass shaft and refillable KCl electrolyte
- Platinum wire diaphragm for clog resistance
- Integrated temperature sensor
- Impact-resistant cone membrane for fast response
- Multiple configurations with plug options
The SenTix® 81-87 pH electrodes with their high-quality glass shaft and refillable 3 mol/l KCl liquid electrolyte and platinum diaphragm are suitable for demanding measurements in the laboratory. The platinum wire diaphragm offers optimum electrolyte flow without clogging and the liquid electrolyte offers fast response times. The electrodes can also be used in difficult samples. The cone shape of the membrane is impact-resistant and easy to clean. These electrodes have different temperature sensors (see table “Temp sensors & Connections Variants”).
The SenTix® 81-87 are particularly suitable for the following applications:
