Zirkon® DIS and Zirkon® DIS TCL sensors are stored and shipped in a 3M KCl solution. In the presence of oxygen the 3M KCl solution will crystallize, creating an invisible barrier between the metallic measuring electrodes and the analyzer water sample.
It is recommended that all disinfectant sensors (NEW and OLD) should be manually, thoroughly cleaned with for example a soft paper towel. Heavy contamination can be cleaned with a small amount of abrasive detergent. Please avoid any detergents on the diaphrgma area. After each cleaning please thoroughly rinse with dionised water before installation.
Example
The below image shows a Zirkon® DIS calibration results of a sensor calibrated without initial cleaning (7.2 mV/0.10 mg/L) and a calibration after manual cleaning (16.5 mV/0.10 mg/L). The first calibration produced sluggish and nonreactive response to chlorine concentration fluctuations (as expected). The second calibration is more fitting to the expected and ideal calibration expected at factory.
Upon clean and proper calibration the ASR® automatic sensor cleaning technology is then intended to keep the sensor clean.
