Hanna HI9913-2 壁挂式酸度pH-电导率EC 控制器

pH Range : 0.00 to 14.00 pH
pH Resolution: 0.01 pH
pH Accuracy: ±0.02 pH
pH Calibration: through “OFFSET” and “SLOPE” trimmers
pH Dosing Set Point: from 4.0 to 7.0 pH
EC Range 0.00 to 10.00 mS/cm
EC Resolution 0.01 mS/cm
EC Accuracy ±2% F. S
EC Calibration: through “ZERO CAL” and “SLOPE CAL” trimmers
EC/TDS Dosing Set Point : from 900 to 1800 ppm (mg/L)
General Meter
pH Electrode: Combination pH electrode with a universal BNC connector
EC/TDS Probe: 4-ring potentiometric probe with built-in temperature sensor and DIN connector
Process Control Meter
Alarm Relay Range: 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 userselectable interval (0.5 to 2.5 pH), or conductivity
Dosing Control: Proportional Control: Two independent controls: pH from 0.0 to 2.0 and Conductivity (EC) from 0.0 to 2.0 mS/cm with two separate time cycles from 0 to 90 seconds
Dosing Terminals: Two sets of independent terminals (115 to 240V, Max.2A, 1,000,000 strokes) are activated whenever pH exceeds the pH setpoint and/or conductivity falls below the EC setpoint
Enclosure: Fiber-reinforced, self-extinguishing ABS
Power Supply: 110/115V at 50/60Hz
Environment: -10 to 50°C (14 to 122°F) max. 95% RH non-condensing
Dimensions: 181 x 221 x 142mm (7.1 x 8.7 x 5.6")
Weight: 1.6 Kg (3.5 lb.)
