The Hanna HI 98188 waterproof, portable Conductivity Meter has an expanded conductivity range, as well as resistivity and 3 salinity scales.

This meter automatically recognizes the probe type (2 or 4-ring) and allows the user to adjust the nominal cell constant. Choose from 7 memorized standards and obtain up to a 5-point calibration. For salinity (% range), HI 7037 buffer allows you to make a 1-point calibration.

Both linear and natural water temperature compensation is available and the reference temperature in user adjustable. Ten sets of measurement parameters (such as reference temperature, temperature compensation mode, TDS factor, calibration etc.) can be stored as a customized user profile and recalled for later use.

HI 98188 is also USP 645 compliant with stages 1, 2 and 3. Data may be captured by either the log-on-demand option (400 samples) and by interval logging (from 5 sec to 1 minute). Return to the lab and download all data to your PC with the USB connection and Hanna’s HI 92000 software.

A combination of dedicated and soft keys allows quick, intuitive operation in a choice of languages. Comprehensive GLP data are directly accessible by pressing the GLP key. Access the contextual Help Menu to obtain on-screen information and assistance about each feature, at the touch of a button.

Designed for field use, this instrument can be easily operated with one hand and is housed in a rugged carrying case. With an extended battery life of up to 100 hours the user is assured of a long operation time. The inductive charger can either be plugged into a standard 115V socket with the adapter included or a 12 Vdc source, such as a car’s 12 V accessory outlet.

The HI 98188 is supplied with HI 76313 4-ring conductivity probe with built-in temperature sensor, calibration solution; (4) 1.2V AA, 1300 mAh rechargeable batteries; HI 710042-01 inductive battery charger with power adapter; rugged carrying case and instructions.
