Description

The CON90 is a portable, highly accurate and full-featured meter that can be used for many applications requiring the measurement of conductivity, total dissolved solids (TDS) and salinity. The CON90 has a large LCD that can display conductivity, TDS or salinity simultaneously with temperature and time. Readings can be displayed in µSiemens, mSiemens, parts per million (ppm) or parts per trillion (ppt).

The CON90 features an Auto Lock Measurement function that can sense when a stable endpoint is reached and then locks that measurement to ensure accuracy and consistency. Accuracy is also assured through multi-point calibration that allows the CON90 to be calibrated at up to five different points.

Other key features include a system that automatically switches to the next higher range, the ability to use probes of different cell constants (0.1, 1.0 and 10.0) and an adjustable TDS factor (0.4 to 1.0) to increase accuracy.

The CON90 is able to save up to 99 data points simultaneously with date and time. This data can be downloaded by USB cable to a PC and viewed with an optional software package (please see below).
