HI 8615LN

ORP Transmitter with 4-20 mA Galvanically Isolated Output with LCD screen

The HI 8615 has been designed for transmitting ORP measurements from remote locations.

This improved transmitter features two controls (one for 4 mA and one for 20 mA) to compensate for electronic drift and ambient temperature.

The HI 8615 uses a universal BNC socket for quick and secure connection of any ORP electrode with a BNC connector.

An IP65 rating and a rugged ABS casing provide optimum protection even in harsh environments making this instrument ideal for chromium hexavalent reductions and water sanitation. The transmitter can be connected to HANNA meters HI 8512, HI 8720 or any recorders, PC’s or data monitors that accept 4 to 20 mA input.
