Description
Overview
GAOTek digital pool chlorine meter is the basic version of the company’s online residual chlorine detector, with 4 mA to 20 mA output, customizable RS 485 Modbus communication protocol interface. This sensor uses polarographic measurement and requires PH value compensation, so we will provide a PH sensor for free.
