EHI98191 Professional Waterproof Meter pH/ORP/ISE
Designed for professionals The HI98191 is a rugged, portable pH/ORP/ISE meter with the performance and features of a benchtop meter. Exchange out the pH probe for an ORP probe to obtain mV readings in the ±2000mV range. This professional, waterproof meter can easily be operated with one hand and complies with IP67 standards. The HI98191 is supplied with all necessary accessories to perform a pH/temperature measurement packaged into a durable carrying case.
- Extensive choice of units to display readings (ppm, ppt, g/L, µg/L, mg/L, M, mol/L, mmol/L, %, w/v, user)
- IP67 rated waterproof, rugged enclosure
- Alerts users to problems during pH calibration including dirty/broken electrode, contaminated buffer and overall probe condition
- Automatic or manual temperature compensation, pH sensors incorporate a builtin temperature sensor
- Up to a five-point pH calibration with seven standard buffers and five custom buffers available
- Approximately 200 hour battery life, powered by (4) 1.5V AA batteries
- Dot matrix display with multifunction virtual keys
