Ion Mode:

• Multiparameter portable ion meter is equipped with a large backlit LCD display.
• 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.

pH Mode:

• 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 electrode.

ORP Mode:

• Single point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt measurements provide accurate ORP readings.
