HI 98143-22

pH and EC Transmitter with Galvanic Isolated Output designed to be used with the HI 8000 series

The HI 98143 series is designed to accept signals directly from a pH electrode and a conductivity probe at the same time.
Direct connection of the probes to the transmitter assure a positive electrical connection with no signal loss. This transmitter is ideal for remote process control applications.
Four models are available, transmitting a 0-1 V, 0-4 V or 4-20 mA signal. The output signals are proportional to the input signals but independent of changes in load or cable capacitance. Compensation for the effects of temperature for EC measurements are performed by the transmitters’ Automatic Temperature Compenstion circuitry.
The transmitter can be connected to any pH or conductivity controller, recorder, PC or any data monitoring device that accepts 0 to 1 V, 0 to 4 V or 4 to 20 mA input. HI?98143 is an ideal tool for applications that require the monitoring of both pH and conductivity at the same time.
