HI-98143-04 PH AND EC TRANSMITTER WITH ISOLATED OUTPUT
HI-98143-04
HI 98143 is a pH and conductivity transmitter designed to accept signals directly from a pH electrode and a conductivity probe at the same time.
pH and EC Transmitter with Galvanic Isolated Output
The HI-98143 series is designed to accept signals directly from a pH electrode and a conductivity probe at the same time.
The direct probe connection to the transmitter assures a positive electrical connection with no signal loss. This transmitter is ideal for remote process control applications.
The transmitter can be connected to any pH or conductivity controller, recorder, PC or any data monitoring device that accepts 0 to 4 V input. The HI-98143 is an ideal tool for applications that require the monitoring of both pH and conductivity at the same time.
Key features
- Accepts pH electrode and EC probe signals simultaneously
- Direct probe connection; assures a positive electrical connection eliminating signal loss
- Automatic Temperature Compensation
