prevents tampering with settings
Push-button calibration
stores up to three pH calibration points
On-line offset
calibration eliminates system shut-down for routine calibration
Separately adjustable
high and low set point hysteresis bands
Battery back-up of
memory maintains set-up if power fails
Our microprocessor-based pH/ORP controllers offer more features per
dollar than any similarly priced controller. All features are logically
designed for easy use. Controllers are selectable for pH or ORP control;
normally open or closed relay operation; and manual or automatic
temperature compensation.
Model 35100-10 has a 4-20 mA output for remote monitoring and hard
copy recording. Both models have 1/8 DIN housing, a BNC connector on the
back to connect pH electrode and screw terminals for VAC power and
control relays. They include hardware to install controllers in panels
or NEMA rated boxes.
