Automatic Temperature Compensation (ATC)
Temperature compensation is performed by the transmitter’s ATC (Automatic Temperature Compensation) circuitry when measurements are taken with a temperature probe attached; if ATC is not required, it is also possible to substitute a fixed resistor for the temperature probe.
Easy Calibration
Calibration is performed by the adjustment of two independent trimmers — slope and offset.
Flexible for Your Needs
The transmitter can be connected to any Hanna controller that accepts analog input.
BNC Connector
The transmitters use a universal BNC socket for quick and secure connection to any electrode with a BNC connector.
Isolated Input
The input is isolated from the current loop to eliminate problems related to ground loop, low insulation cables, multiple electrode connections, and a common mode voltage of up to 100V ensures true differential readings.
Version with LCD
HI8614”L” versions allow easy verification and monitoring of measured values and is easier to calibrate and maintain.
