This pH Sensor is the latest digital pH electrode independently researched, developed, and produced by BOQU Instrument. The electrode is light in weight, easy to install, and has high measurement accuracy, responsiveness, and can work stably for a long time. Built-in temperature probe, instant temperature compensation. With strong anti-interference ability, the longest output cable can reach 500 meters. It can be set and calibrated remotely, and the operation is simple. It can be widely used to monitor the ORP of solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food, and tap water.
