The transmitters use a universal BNC socket for quick and secure

connection to any electrode with a BNC connector.

For HI 8614

family models the temperature compensation is

performed by the transmitter's ATC circuitry if the temperature probe

(HI 76608, optional) is attached. If ATC is not required, it is possible

to substitute the temperature probe with a fixed resistor.

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 100 V ensures true

differential readings.

The terminal board of the transmitter provides for connection of power

supply, pH or ORP electrodes and temperature probe (for HI 8614

family models only).

The unit is enclosed in a protective casing conforming to IP 65

standards.
