Bante 904P portable multi-parameter meter used for measuring the Conductivity, TDS, Salinity, Resistivity and DO in water. General Features: Automatic Temperature Compensation (ATC) ensures highly accurate     measurements over the entire range. Calibration due reminder prompts you to calibrate the meter regularly. Automatic endpoint function freezes the stable measured values for     easy reading and recording data. Manual temperature calibration provides accurate temperature value. Help message as a operational guide to helps you understand how     to use meter. Setup menu lets user customizes calibration points, stability condition,     resolution, temperature units, date and time to meet measurement     requirements. Reset function can resumes all settings to factory default values. Expanded memory stores and recalls up to 500 readings. Built-in real-time clock stamps stored data to meets GLP standards. Stored data can be transferred into computer via USB communication     interface.
