ALARM
CONTACT
POWER SUPPLY 220/240V or 110/115V at 50/60Hz
DOSING
TERMINALS
ENVIRONMENT -10 to 50°C (14 to 122°F)
max. 95% RH non-condensing
Through "OFFSET" and "SLOPE" trimmers for pH, and
“ZERO CAL” and “SLOPE CAL” for Conductivity
DEAD BAND From 0.0 to 0.5 mS/cm (mmho/cm)
Terminals can be configured as normally open or
normally closed (isolated output Max. 2A, Max. 240V,
resistive load, 1,000,000 strokes). The alarm is activated
if pH exceeds the setpoint by the user-selectable interval
(0 to 2 pH), or Conductivity falls below the setpoint by
more than the user-selectable interval (0 to 2.0 mS/
cm) or due to overdosage
Two sets of independent terminals (115 to 240V, Max.
2A, 1,000,000 strokes) are activated whenever pH falls
below the pH setpoint or the conductivity exceeds the
“BLEED” setpoint
PROBE
Any combination pH electrode with a universal BNC
connector and Hanna Conductivity 4-ring
potentiometric probe with built-in temperature sensor
and DIN connector (optional)
