Description

The Signet 5700 pH/ORP Monitor is a
versatile and intelligent instrument
that recognizes the type of sensor
connected, either pH or ORP, then
automatically sets itself for the cor­responding display and functionality.
Also, during EasyCal operation, the
monitor automatically recognizes
standard buffers/test solutions,
thereby shortening and simplifying
routine calibration procedures. Two
programmable relays and one scale­able 4 to 20 mA output are included,

and the four-button keypad arrange­ment with intuitive software design
is very user-friendly. The monitors
require 12 to 24 Volts, AC or DC, and
can be used with many Signet pH/ORP
electrodes and preamplifiers, or with
electrodes from other manufacturers
by using the 2721 Preamplifier. Sev­eral useful accessories are available,
including the optional splashproof rear
cover kit.
