- Compact waterproof design
- Automatic Temperature Compensation (ATC)
- Automatic one or two-point calibration
Waterproof – Compact, heavy duty casing that is protected against any ingress of water that would damage the electronics.
Automatic Calibration – calibration to one or two points to any of the three programmed buffer values (pH 4.01, 7.01, and 10.01).
Automatic Temperature Compensation – Separate temperature probe is supplied to provide temperature compensated measurements.
High Resolution/Accuracy mV Range – The HI8424 automatically switches resolution from 1 mV to 0.1 mV when ORP readings are between -699.9 to +699.9 mV. The accuracy within this range is ±0.2 mV.
Automatic Shutoff – The automatic shutoff feature will turn the meter off after 20 minutes to conserve battery life.
Low Battery Indicator – A low battery indicator will be displayed when the battery life is almost exhausted (5% remaining) alerting the user that a new battery will be needed in the near future.
