The alpha pH 2000D is used for measuring pH, ORP and temperature
values. Built-in non-volatile memory to ensure that
calibration and other information are not erased if power supply
fails. Automatic temperature compensation (ATC). Two galvanically
isolated current outputs 0/4-20mA. Two switching contacts
as set-point relays. 0 to 2000 seconds time delay adjustment on
all relays – minimizes false alarms. Separately adjustable high
and low set-point hysteresis (dead bands) prevent chattering of
relays around the set points. Separate alarm relay alerts user
to set point limits exceeded for a certain time and if the Pt100/
Pt1000 or NTC300 thermistor wires are broken or disconnected
during the ATC function.
Order probe and controller separately.
