HANNA HI981412-00 pH控制系统 (0.00~14.00 pH)

Range: 0.00 to 14.00 pH*, -5.0 to 105.0 °C (23.0 to 221.0 °F)

Resolution: 0.01 pH; 0.1 °C (0.1 ºF)

Accuracy @ 25 °C / 77 °F: ±0.10 pH; ±0.5 ºC (±0.9 ºF)

Calibration: User calibration: automatic, one or two-point with buffer solution (4.01, 7.01, 10.01 pH)

Process calibration: single point, adjustable (±0.50 pH around measured pH)

Temperature Compensation: Automatic

High or Low Mode Operation Pump Control:

- On/Off control using adjustable set point (4.00 - 10.00 pH) with adjustable hysteresis (0.10 to 1.00 pH)

- Proportional control using adjustable set point (4.00 - 10.00 pH) with adjustable proportional band (0.10 to 2.00 pH)

- Startup delay timer at power-on (0 to 600 sec.)

- Pump flow control 0.5 to 3.5 Litre/hour (0.13 to 0.92 Gallon/hour) and maximum output pressure 1 atm (14 psi)

- Manual control for pump priming (defined in setup)

pH Alarms:

- High & Low with enable or disable option

- Triggered after 5 sec. if the controller records a set of consecutive readings over or under threshold values

- Level with enable or disable option

- Overtime protection (1 to 180 min. or Off)

Controller Alarm System:

- Intuitive alarm system, using red, yellow and green colour coded backlight

- User-selectable, alarm setup options

Alarm Relay Output:

- SPDT 2.5A / 230 Vac

- Activated by pH-selectable alarm conditions

Probe Input:

- Quick connect DIN connector

- Galvanic isolation

Digital Input:

- External switches can be attached to hold the control due to external events (low reagent level, recirculation pump doesn’t work)
