Conductivity Transmitter to use with Four-ring Probe - HI8936
- Automatic temperature compensation ensures fast, accurately compensated readings even during sudden temperature fluctuations.
- Optional backlit, LCD display for easy viewing.
Easy Installation
The HI 8936 transmitter may be wall-mounted at any convenient location close to the measurement site. The HI8936 series should be used in conjunction with the HI7635 in-line probe or HI7638 platinum probe.
Automatic Temperature Compensation
Temperature effects are compensated for by utilizing both the built-in temperature sensor on the probe and the transmitter’s ATC circuitry with a of 2%/°C.
Optional LCD
HI8936”L” versions allow easy verification and monitoring of measured values and is easier to calibrate and maintain.
Direct Probe Connection
Direct connection of the probe to the transmitter assures a positive electrical connection with no signal loss over long distances.
