Bright, backlit LCD with ready indicator



These single-channel meters provide reliable and accurate conductivity, TDS, salinity, resistivity, and temperature measurements for soil and water analysis in the lab or the field. The meters can record and store up to 10 password-protected methods and calibrations for consistent operation with multiple users. Additional methods and software updates can be downloaded via the Internet. The meters store up to 200 data points with time- and date-stamp for GLP compliance. Download the data to a printer or computer using the optional RS-232 cable. The benchtop meter allows the addition of the optional auto stirrer to mix samples without using a stir plate and stir bar.

Benchtop meter only include: Universal power supply. Order additional accessories separetly at right.
