over the 0-14 pH range with isolated output

CALIBRATION Through "OFFSET" and "SLOPE" trimmers

(Max. ±1.5 pH for offset and 80% to 110% for slope)

SETPOINT From 0.00 to 14.00 pH with "COARSE" and "FINE"

RANGE trimmers with "ACID" or "ALK" (alkaline) selection

CONTROL time cycle from 0 to 90 seconds

DOSING TERMINALS Relay terminals (115 to 240V, Max.2A,1,000,000

strokes) are activated when pH exceeds the setpoint with

“ACID” dosage or falls below the setpoint with “ALK”

selection (Alkaline dosage)

ENVIRONMENT -10 to 50 °C (14 to 122 °F)

max. 95% RH non-condensing

ENCLOSURE 181 x 221 x 142mm (7.1 x 8.7 x 5.6")

CASE MATERIAL Fiber-reinforced, self-extinguishing ABS

POWER SUPPLY 220/240V or110/115V at 50/60Hz

TEMPERATURE

COMPENSATION

Manual from -10 to 80 °C (14 to 176 °F) or

automatic with a 3-wire Pt 100 probe from 0 to 50

°C (32 to 122 °F)

ALARM

CONTACT

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 varies by more than user-selectable

interval (0 to 2 pH) from setpoint or due to overdosage
