Water-resistant portable EC, TDS and resistivity meter | S/M

The HI-98192 is a waterproof, portable conductivity meter that has an expanded conductivity range from 0.000µS/cm to 400 mS/cm, as well as TDS, resistivity and three salinity scales.
The HI-98192 is a waterproof, portable conductivity meter that has an expanded conductivity range from 0.000µS/cm to 400 mS/cm, as well as TDS, resistivity and three salinity scales. This meter automatically recognises the probe type (two or four ring) and allows the user to adjust the nominal cell constant.
HI-98192 is also ready to perform all three stages USP 645 method required for EC measurement of ultrapure water. Choose from seven memorised standards and obtain up to a five point conductivity calibration. For salinity (% range), HI-7037 standard allows users to make a one point calibration.
EC and TDS measurements are fully customisable and include: cell constant selection between 0.010 and 10.000, selection of linear or natural water (non-linear) or no temperature compensation (for actual conductivity reading), configurable temperature compensation coefficient range from 0.00 to 10.00%/°C, choice of reference temperatures of 15°C, 20°C and 25°C, and a selectable TDS factor between 0.40 and 1.00.

Calibration
Choose from seven memorized standards and obtain up to a five point conductivity calibration. For salinity (% range), HI-7037 standard allows users to perform a one point calibration.
USP 645
HI-98192 can be used to perform all three stages of USP method required for EC measurement of ultrapure water and generates a report when the any of the three stages are met.
Three stages of conformity:

Performs all 3 stages of USP 645 water quality testing requirements

On-screen guide:

Users are provided with on-screen instructions for each USP stage

Progress bar:

Displays reading stability progress towards meeting stage 2 requirements

Measurement
EC and TDS measurements are fully customizable and include: cell constant selection between 0.010 and 10.000, selection of linear or natural water (nonlinear) or no temperature compensation (for actual conductivity reading), configurable temperature compensation coefficient range from 0.00 to 10.00%/°C, choice of reference temperatures of 15°C, 20°C and 25°C, and a selectable TDS factor between 0.40 and 1.00. Ten sets of customized measurement parameters can be stored as a user profile and later recalled.
AutoHold
Pressing AutoHold during measurement will automatically hold the first stable reading on the display.
Dedicated Help Key
Contextual help is always available through a dedicated “HELP” key. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration. The help information displayed is relative to the setting/option being viewed.
