Introduction
The industrial pH meter HP-100 consists of the pH sensor, the sensor holder, the transmitter,
and the power unit that supplies the power to these components through two lines, receives
signal and provides the output to the extemal receiving instrument.
This manual provides explanation for the two-wired transmitter. For other units, refer to
individual instruction manuals.
This transmitter is a field insulating-type converter. By connecting the lead wire of the
electrode of fixture and connecting power supply of approx. 22.5 V to 30 V DC, this converter
transmits the pH measured value as a signal of 4 mA to 20 mA DC, overlapping the supply
power line (2 wires).
The measured value is displayed on the LC digital meter.
