Laboratory pH/ORP/Temperature 3 in 1 Meter, Multi-parameter Water Quality Meter, Datalogger, USB Communication, PH920
Standard benchtop pH meter, 5 points calibration, automatic temperature compensation, system menu contains 9 optional parameters. Accuracy: 0.002pH.
pH Mode: • High accuracy benchtop pH meter is equipped with a large backlit LCD display. • 1 to 5 points push-button calibration with auto-buffer recognition. • Selectable pH buffer standards (USA/NIST/DIN) or using the custom calibration solutions. • Automatic electrode slope display helps you decide whether to replace sensor. • Automatic Temperature Compensation provides accurate reading over the entire pH range. • Calibration Due Reminder prompts user to calibrate the meter regularly.
ORP Mode: • Single point offset calibration allows adjusting the displayed value to a known standard. • Relative and absolute millivolt measurements provide accurate ORP readings.
Other Features: • Stability indicator shows current measurement status automatically. • Auto-Hold function freezes stable measured value for easy viewing and recording. • Manual temperature calibration improves the measurement accuracy of meter. • Selectable temperature unit (°C or °F) meets different application requirements. • Automatic electrode diagnosis shows zero point offset and slope of the electrode. • Help message as a operational guide that helps you quickly begin using the meter. • System menu allows setting the 9 parameters, including the pH buffer standards, calibration points, resolutions, stability conditions, temperature units, etc. • Reset feature automatically resumes all parameters back to factory default options. • Expanded memory stores and recalls up to 500 readings. • Built-in real-time clock stamps stored data to meet GLP standard. • Stored data can be transferred into computer by USB communication interface.
