APT11 Industrial pH/ORP Meter
The Industrial pH/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.
