IC2-KIT (pH Meter + Perchlorate) The perchlorate ion analyser, combined with the pH sensor, includes advanced analysis software that displays real-time measurements and facilitates identification. The software also allows custom calibrations with up to five set points, among other features. Continuous monitoring is available for short-term reactions or process studies. The perchlorate ion sensor is modular and can be replaced with a new perchlorate sensor or any other sensor from our catalogue. It is important to note that the ISE sensor has a limited lifetime, even when not in use, whether stored on a shelf or installed in a probe. Generally, the perchlorate sensor achieves a lifetime in excess of 12 months. The lifetime may vary between different sensors, sometimes by several months, even under the same conditions.
