Product Description
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.
