Description
Overview
GAOTek push electrical switch is an online water quality monitoring instrument with a microprocessor. This instrument is equipped with conductivity electrodes of different types and constants for continuous monitoring and control of the conductivity and temperature values of aqueous solutions. Widely used in fields such as power plants, petrochemicals, metallurgy, paper industry, environmental water treatment, light industry electronics, etc. Monitoring and control of raw and produced water quality for water production equipment such as power plant cooling water, make up water, saturated water, condensate and boiler water, ion exchange, reverse osmosis EDL, and seawater distillation. The instrument adopts an LCD display screen; Intelligent Chinese menu operation; Equipped with 2 current outputs, freely set measurement range, high and low limit alarm prompts, two sets of relay control switches, adjustable hysteresis range, and automatic cleaning switch settings; Automatic or manual temperature compensation; Multiple automatic calibration methods for electrodes. According to user needs, electrodes can be installed in various forms such as flow through, immersion, pipeline, and flange.
