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 TDS
Two independent controls: pH from 0.0 to 2.0 and
TDS from 0.0 to 400 ppm (mg/L) with two separate
time cycles from 0 to 90 seconds
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 falls below the setpoint by the user-
selectable interval (0 to 2 pH),or TDS exceeds the
setpoint by more than the user-selectable interval (0
to 400 ppm) or due to overdosage
TDS RATIO 0.65 ppm (mg/L) = 1 µS/cm
Two sets of independent terminals (115 to 240V, Max.
2A, 1,000,000 strokes) are activated whenever pH
exceeds the pH setpoint and for the TDS falls below
the TDS setpoint
PROBE
Any combination pH electrode with a universal BNC
connector and Hanna TDS 4-ring potentiometric probe
with built-in temperature sensor and DIN connector
(optional)
