Specifications HI 9912
RANGE 0.00 to 14.00 pH and 0 to 1000 mV
RESOLUTION 0.01 pH and 1mV
ACCURACY ±0.02 pH and ±5 mV
(@20°C/68°F)
TYPICAL EMC ±0.1 pH and ±6 mV
DEVIATION
CALIBRATION Through "OFFSET" and "SLOPE" trimmers for pH and
“CAL” for ORP
WEIGHT 1.6 Kg (3.5 lb.)
ENCLOSURE 181 x 221 x 142mm (7.1 x 8.7 x 5.6")
CASE MATERIAL Fiber-reinforced, self-extinguishing ABS
SETPOINT RANGE From 6 to 8 pH and 500 to 900 mV
PROPORTIONAL Two independent controls: pH from 0.0 to 2.0 and
CONTROL ORP from 0 to 200 mV with two separate time cycle
from 0 to 90 seconds
ALARM Relay can be configured as normally open or normally
CONTACT closed (isolated output Max. 2A, Max. 240V, resistive
load, 1,000,000 strokes). The alarm is activated if pH
varies by more than the user-selectable interval (0 to
2 pH), and/or ORP varies by more than the user
selectable interval (0 to 200 mV) from the setpoints or
due to overdosage
POWER SUPPLY 220/240V or 110/115V at 50/60Hz
DOSING
TERMINALS
Two sets of independent terminals (115 to 240V,
Max.2A, 1,000,000 strokes) are activated whenever
pH exceeds the pH setpoint or when ORP falls below
the mV setpoint
ENVIRONMENT -10 to 50°C (14 to 122°F)
max. 95% RH non-condensing
