HI 98188 is a waterproof, portable conductivity meter that has an expanded conductivity range from 0.001 µS/cm to 400 mS/cm,
as well as TDS, resistivity and three salinity scales. This meter automatically recognizes the probe type (two or four ring) and allows
the user to adjust the nominal cell constant. HI 98188 is also ready to perform all three stages of USP <645> method required for
EC measurement of pure and ultrapure water.
Choose from seven memorized 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 customizable and include: cell contant selection between 0.0 and 10.000, selection of linear or
natural water (non-linear) or no (for actual conductivity reading) temperature compensation, configurable temperature compensation
coefficient range from 0.00 to 10.00%/ºC, choice of reference temperatures of of 15ºC, 20ºC and 25ºC 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 recalled for later use.
Data may be captured by either the log on demand option (400 samples) or by interval logging (from 5 sec to 1 minute).
Data can be transferred to a PC using HI 92000 software and HI 920013 USB cable.
A combination of dedicated and soft keys allows quick, intuitive operation in a choice of languages. Comprehensive GLP data is directly
accessible by pressing the GLP key. At the touch of a button users can access the contextual help menu to obtain on-screen information
and assistance about each feature.
Designed for field use, this instrument can be easily operated with one hand and includes a rugged carrying case. With an extended
battery life of up to 100 hours, users are assured long operation. 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 volt accessory outlet.
