Designed for universal applications, Hanna Instruments-98191 measures pH/ORP/ISE and temperature. Exchange out the pH probe for an ORP probe to obtain mV readings in the ±2000 mV range. Hanna Instruments-98191 adds direct ion concentration readings for ISEs with a choice of units for calibration and display.

A backlit, graphic LCD provides easy to read resolution even in low-lit areas. A combination of dedicated and soft keys allows for intuitive operation in a choice of languages while the extended battery life assures long operation.

Data Logging

The log-on demand feature allows users to store up to 300 sample that can be later transferred to a PC with the Hanna Instruments-920015 USB cable and Hanna Instruments-92000 software.

ISE Sensors and Calibration

Hanna Instruments-98191 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, µg/L, mg/mL, M, mol/L, mmol/L, % w/v, user) and has an expanded measuring range of 1.00 x 10^-7 to 9.99 x 10¹⁰.
