Product Description

221 Portable ORP Meter

High-accuracy portable ORP meter, 1 point calibration, setup menu contains 9 options. The meter is suitable for outdoor applications, accuracy: 0.2 mV.

ORP Mode:
• High-accuracy portable ORP meter is equipped with a backlit LCD display.
• 1 point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt modes ensure the reliable ORP measurements.

pH Mode:
• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
• Automatic electrode diagnosis helps the user decide whether to replace the pH electrode.
• Automatic temperature compensation ensures accurate readings over the entire range.



Other Features:
• Auto-Read function senses and locks the measurement endpoint.
• Auto-Power Off effectively conserves battery life.
• Setup menu allows setting the resolution, stability criteria, date and time, etc.
• Reset function automatically resumes all settings back to the factory defaults.
• Expanded memory stores or recalls up to 500 data sets.
• USB communication interface is used to transfer data or connect a power adapter to meter.
