Multi parameter water testing equipment Multi parameter water testing equipment During the pH mode, Up to 5 points push-button calibration with auto-buffer recognition Selectable p H buffer standards and temperature units. Automatically calculates and displays electrode slope after calibration. During the ion mode, 2 to 5 points push-button calibration from low to high concentrations Direct readout ion concentration simplifies the elaborate measurement process. Automatic Temperature 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 a operational guide to helps you understand how to use meter. Setup menu lets user customizes buffer standards, calibration points, stability conditions, resolution, measurement units, date and time to meet measurement requirements. Reset function can resumes all settings to factory default values. Built-in real-time clock stamps stored data to meets GLP standards. Stored data can be transferred into computer via USB communication interface MODEL LM-40 SPECIFICATION MAKE LAB pH Range & Accuracy -2.000 - 20.000pH & ±0.002pH Resolution 0.001,0.01,0.1pH ( Selectable ) Ion Concentration Range 0.001-19999 ppm,mg/L,mol/L (Selectable Depending on meas.
