High accuracy 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.
