Membrane probe for direct measuring of free cholrine concentration. Designed for use with ASIN Aqua, ASIN Aqua HOME, ASIN Aqua SALT and ASIN Aqua PROFI.
The electrochemical measurement system is separated from the measured water with special membrane.
Measured chlorine diffuses through the membrane and produces voltage whose magnitude is proportional to chlorine concentration.
Requires galvanically isolated power supply.
2 years warranty. Lifespan can be affected by water-hardness, water contamination, temperature etc.
