Hanna HI9910-2 工业级壁挂式单点设定pH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 Temperature Compensation: automatic from 0 to 50°C with Pt100 probe or manual from -10 to 80°C
Process Control Meter
Alarm Relay Set Point: from 0.00 to 14.00 pH with “COARSE” and “FINE” trimmers with “ACID” or “ALK” (alkaline) selection
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 varies by more than user selectable interval (0.5 to 2.5 pH) from set point or due to ove
Dosing Control: relay terminals (115 to 240V, max.2A,1,000,000 strokes) are activated when pH exceeds the set point with “ACID” dosage or falls below the set point with “ALK” selection (alkaline dosage)
Analog Ouput Signal: user selectable 0 to 20 mA or 4 to 20 mA over the 0-14 pH range with isolated output
Enclosure :fiber-reinforced, self-extinguishing ABS
Power Supply: ±10% 115 VAC; 50/60 Hz
