These meters are simple and easy to use — just add your sample to the built-in cell cup, push the parameter key, and take a reading. Autoranging function automatically selects from five conductivity or TDS ranges. Factory-calibrated meters have conductivity-to-TDS conversion curves for NaCl, 442, and KCl standards stored in memory. You can also calibrate using your own calibration values. Automatic temperature compensation with adjustable temperature coefficients up to 9.99%/°C provides accurate and precise measurements. Easily store and recall up to 100 measurements with time-and-date stamp. Nonvolatile memory retains all data and can be downloaded via bluDock™ accessory ordered separately.
