Features: 2 to 5 points push-button calibration from low to high concentrations. Selectable multiple concentration units, including ppm, mg/L and mol/L. Direct readout ion concentration simplifies the elaborate measurement     process. mV measurement allows user to check performance of ion electrode. AutomaticTemperature Compensation (ATC) ensures highly accurate     measurements over the entire range. Automatic endpoint function freezes the stable measured values for     easy reading and recording data. Calibration due reminder prompts you to calibrate the meter regularly. Help message as aoperational guide to helps you understand how to     use meter. Setup menu lets user customize calibration points, ion concentration     units, stability conditions, 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...
