The WQ420 meter was designed to measure conductivity in groundwater and surface water.
The meter is produced with the interchangeable sensitive element for easy maintenance, allowing a long operation of the instrument.
The meter consists of a glass bulb sensitive to hydrogen ions and a reference electrode. The signal produced in mA is directly proportional to the PH of the liquid being measured.
Thanks to its compact size, with a diameter of 32 mm, the gauge can also be used in small wells.
Each sensor comes with a test certificate which certifies the results of the test performed and the electromechanical characteristics of the same.
