Digital IDS pH electrode, WTW SenTix® 945: Electrode with glass shaft, built-in temperature probe, and an IDS cable. For general measurements, especially where robustness and minimal maintenance are required. With gel electrolyte without refilling. Shipped with fixed cable.

The electrodes in the SenTix® series from WTW are designed to cover the common measurements in pH and mV. The electrodes area available in glass or plastic, for general or specialised purposes, and with a range of junctions/diaphragms, which makes it possible to measure in aqueous solutions, protein-rich samples, solids and viscous samples, on surfaces, and much more. The series is available with and without various cables and temperature sensors, to make it easy to find the correct sensor for your pH meter. Collectively, they represent high quality, low pricing, robustness, and easy use.

IDS - Intelligent Digital Sensors: Conversion of analog measurement signals into digital values directly in the sensor prevents interference and guarantees fail-safe data transmission. IDS electrodes are available with fixed cable or plug head for flexibility with cables up to 100 m in length or connection to wireless modules. Automatic transmission of sensor serial number and calibration record of the sensor increase data integrity. Comprehensive support for GLP-compliant data acquisition.
