Portable pH/ORP/Ion/°C/°F Meter
Multiparameter portable pH meter, 5 points calibration, automatic temperature compensation. The meter is suitable for measuring the pH, millivolts and ion concentration of liquids. Accuracy: 0.002pH, 1% full scale (Ion mode).
pH Mode:
• Multiparameter 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 standards (USA/NIST/DIN) or using the custom calibration solutions.
• Automatically calculates and displays electrode slope that helps you decide whether to replace pH electro
Ion Mode:
• 2 to 5 points calibration including the eight concentration calibration points can be selected.
• Automatically recognize ion selective electrodes, does not need to specify type of ion.
• Direct ion concentration readout simplifies the elaborate measurement process.
• Selectable multiple concentration units for different measurement requirements.
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:
• Automatic Temperature Compensation ensures accurate reading over the entire range.
• Calibration Due Reminder prompts user to calibrate the meter regularly.
• 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 electrode.
• Help message as a operational guide that helps you quickly begin using the meter.
• System menu allows setting the 10 parameters, including the pH buffer standards, number
of calibration points, resolutions, stability conditions, hold function, 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.
