The WQ473 meter is a compact and robust instrument suitable for measuring chloride ions in groundwater and surface water.
The WQ473 uses a solid membrane ion-selective electrode to test for free chlorine ions in water. The internal reference fluid slowly filters from the microporous salt bridge at a pressure of at least 100KPa (1bar). The reference system is very stable and the life of the electrodes is long.
Every sensor is provided with a calibration certificate that attests the results of the test performed and all electromechanical features.
