Select Option
The HI8614N is a water-resistant pH transmitter is designed to be used with a standard high impedance pH probe with BNC connector. The signal is then processed by a special highimpedance amplifier, which transmits an output current directly proportional to the input signal but independent of changes in load or cable capacitance.
- Temperature compensation ensures fast, accurately compensated readings even during sudden temperature fluctuations.
- Water resistant design for use in process control.
- Optional backlit, LCD display for easy viewing.
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.
BNC Connector
- The transmitters use a universal BNC socket for quick and secure connection to any electrode with a BNC connector.
Easy Calibration
- Calibration is performed by the adjustment of two independent trimmers — slope and offset.
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
Flexible for Your Needs
- The transmitter can be connected to any Hanna controller that accepts analog input.
Version with LCD
- HI8614”L” versions allow easy verification and monitoring of measured values and is easier to calibrate and maintain.
