EC/TDS Resistivity Salinity Professional Waterproof Meter

The HI-98192 is a versatile, waterproof, portable conductivity meter with an extensive conductivity range spanning from 0.000?S/cm to 400 mS/cm. It also offers measurements for TDS, resistivity, and three salinity scales. The meter intelligently detects the probe type (two or four ring) and allows users to adjust the nominal cell constant. For ultrapure water conductivity measurements in accordance with the USP <645> method, the HI-98192 is equipped to handle all three stages. You can choose from seven preset standards and perform a five-point conductivity calibration. When it comes to salinity, a one-point calibration is possible using the HI-7037 standard. The meter provides full customization for EC and TDS measurements, including selecting a cell constant between 0.010 and 10.000, choosing between linear or natural water (non-linear) or no temperature compensation for actual conductivity readings, configuring the temperature compensation coefficient within a range of 0.00 to 10.00%/°C, selecting reference temperatures of 15°C, 20°C, or 25°C, and choosing a TDS factor between 0.40 and 1.00.
