pH Mode:
? Professional portable pH meter is equipped with a large backlit LCD display.
? 1 to 5 points push-button calibration with auto-buffer recognition.
? Selectable pH buffer standard (USA/NIST/DIN) or using the custom calibration solutions.
? Automatic electrode slope display helps user decide whether to replace sensor.
? Automatic Temperature Compensation provides accurate reading over the entire pH range.
? Calibration Due Reminder prompts you to calibrate the meter regularly.
ORP Mode:
? Single point offset calibration allows adjusting the displayed value to a known standard.
? Relative and absolute millivolt measurement modes provide accurate ORP readings.
Other Features:
? Stability indicator automatically shows current measurement status.
? 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 pH 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 standard, number of
calibration points, resolution, stability condition, temperature unit, 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.
? Multi-mode power scheme (battery, power adapter, computer's USB port) ensures that use
the meter smoothly.
