Description
Overview
GAOTek Supply Free Chlorine Analyzer is a wall-mounted online analyzer integrated the measurement of water quality free chlorine, pH, and temperature. The instrument adopts the latest research results of the constant potential sensor application, internally configurated water sample decompression, filtration, and constant flow rate device, which create a sustained and stable operating environment for the sensor, rather than simply matching sales of the sensor and instruments.
