Description

Features PH920 Precision pH/mV/ORP/Temp Meter

• During the pH mode, Up to 5 points push-button calibration with auto-buffer recognition.
• Selectable pH buffer standards and temperature units.
• Automatically calculates and displays electrode slope after calibration.
• Automatic Temperature Compensation (ATC) ensures highly accurate measurements over the entire range.
• Calibration due reminder prompts you to calibrate the meter regularly.
• During ORP mode, Single point offset calibration allows user adjusts displayed value to a known standard.
• Absolute or Relative millivolt (R.mV) measurement provides accurate ORP readings.
• 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 buffer standards, calibration points, stability conditions, 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
