Bante950 is a professional multi-range conductivity meter which used for measuring the conductivity, TDS, salinity and resistivity of liquids. Features: Up to 5-point push-button calibration allows user to uses customized     calibration solutions. Adjustable TDS factors, cell constants, temperature coefficients and     normalization temperature. In salinity measurement modes, selectable practical salinity (PSU) or     seawater measurement standard (ppt). Automatic Temperature Compensation (ATC) ensures highly accurate     measurements over the entire range. Manual temperature calibration provides accurate temperature value. Selectable either temperature units between degrees Celsius (°C)     and degrees Fahrenheit (°F). Selectable linear or pure water compensation modes. Calibration due reminder prompts you to calibrate the meter regularly. Automatic endpoint function freezes the stable measured values for     easy reading and recording data.
