Peristaltic Dosing Pump The powerful built-in peristaltic pump uses a stepper motor which does not have any gears or brushes providing for a long life with little maintenance. Automatic Proportional Pump Control The peristaltic dosing pump can be controlled by simple on/off or more advanced proportional control which helps prevents overshooting of the set point. Adjustable Flow Rate The dosing pump flow rate is adjustable from 0.5 to 3.5L/h, allowing for better control in maintaining a desired set point. Acid Tank Level/Flow Switch Input A connection to an optional level controller or flow switch. This input can be used to disable the dosing pump when there is no chemical left in the reservoir tank or there is no flow due to the pump being turned off. Multicolored LCD Display A multi-colored LCD provides a quick way to see the status of the pool controller. The display will show green when operation normally and red while in an alarm state. Quick Connect Probe Input The Quick Connect DIN connector creates a waterproof seal with the meter making it ideal for reducing electrical noise issues with the connection caused by humid environments. GroLine pH/Temperature Probe The HI981412 uses the HI10063 amplified probe that incorporates both pH and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector.
| Range | 0.00 to 14.00 pH*, -5.0 to 105.0 °C (23.0 to 221.0 °F) * The range may be limited by the probe’s limits. |
|---|---|
| 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 |
| 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 |
| Alarm Relay Output | – Activated by pH-selectable alarm conditions – Quick connect DIN connector |
| Probe Input | – Galvanic isolation – External switches can be attached to hold the control due to external events (low reagent level, recirculation pump doesn’t work) |
| Power Supply | 100 – 240 Vac, 50/60 Hz |
| Environment | 0-50 oC (32-122 oF), max. 95% RH non-condensing |
| Dimensions | 90 x 142 x 80 mm (3.5 x 5.6 x 1.8”) |
| Weight | 908 g (36 oz) |
