Water resistant portable EC / TDS / temp meter, up to 20 mS | S/M

The HI-98191 combines all of the features of a bench top into a portable IP67 rated waterproof enclosure making them one of the most versatile meters on the market.
The HI-98191 combines all of the features of a benchtop into a portable IP67 rated waterproof enclosure making them one of the most versatile meters on the market.
Designed for universal applications, HI-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. HI-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.
The HI-98191 features the HI-72911B titanium bodied pH/temperature electrode with BNC and RCA connectors.
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 HI-920015 USB cable and HI-92000 software.
ISE Sensors and Calibration
HI-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¯? to 9.99 x 10¹?.
