GENERAL DESCRIPTION
HI 8614 / HI 8614L (pH) and HI 8615 / HI 8615L
(ORP) are 2-wire water-resistant transmitters
specially designed for long distance mea-
surement of pH or ORP in industrial applica-
tions.
Two versions are available: the standard
HI 8614 and HI 8615, and the HI 8614L and
HI 8615L models with LCD.
The LCD allows easy verification and moni-
toring of measured values, and provides easier
calibration and maintainance.
The pH or ORP signal is transmitted in a 2-
wire current loop in the range of 4 to 20 mA.
HI 8614 and HI 8614L can be connected to
the Hanna process instruments HI 8510T,
HI 8710T or HI 8711T, or to any recorder,
computer or data monitoring device that ac-
cepts 4 to 20 mA input.
HI 8615 and HI 8615L can be connected to
the Hanna meters HI 8512T, HI 8720T or to
