The pH and ORP Meter collects pH and temperature signals from the solution via a pH electrode. The signals are processed by the monitor and converted into a standard pH value, which is displayed and transmitted through relay outputs, analog signals (4-20mA, 0-5V, etc.), and RS485 communication for control and monitoring. It features a high-impedance design for stable measurements without fluctuations, precise signal transmission, and manual/automatic temperature compensation. It is widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water industries.
The APT11 Series pH and ORP Meter provides continuous monitoring of the pH or ORP value in solutions. It offers a pH measurement accuracy of ±0.02 and an ORP measurement accuracy of ±1mV. The device supports electrode calibration and features 4-20mA analog signals, RS-485 digital signals, and relay outputs. It is suitable for industrial processes and water treatment applications, with support for remote data transmission.
