Product Description
HI98190 and HI98191 are IP67 rated waterproof meters designed for universal applications. HI98190 measures pH/ORP and temperature while HI98191 also includes ISE measurements. Exchange out the pH probe for an ORP probe to obtain mV readings in the ±2000 mV range. HI98191 adds direct ion concentration readings for ISEs with a choice of units for calibration and display.
The HI98190 features the HI12963 titanium bodied pH/temperature electrode with a quick connect DIN connector to make attaching and removing the probe simple and easy. The HI98191 is supplied with the HI72911B titanium bodied pH/temperature electrode with BNC and RCA connectors. ISE Sensors and Calibration HI98191 has 17 different standard ISE sensors pre-programmed in the meter. Selecting the appropriate sensor will automatically update the ion charge for slope calibration and can be calibrated up to five points with the choice of seven standards and five custom standards (choice of units). This meter allows an extensive choice of measurement units (ppm, ppt, g/L, ppb, �Êg/L, mg/mL, M, mol/L, mmol/L, % w/v, user) and has an expanded measuring range.
ISE measurement units - Extensive choice of units to display readings (ppm, ppt, g/L, ìg/L, mg/L, M, mol/L, mmol/L, %, w/v, user)
CAL Check - Alerts users to problems during calibration including dirty/broken electrode, contaminated buffer and overall probe condition
Automatic or manual temperature compensation - pH sensors incorporate a built-in temperature sensor
Calibration - Up to a five-point calibration with seven standard buffers and five custom buffers available
Approximately 200 hour battery life - Powered by (4) 1.5V AA batteries
