Description

Product introduction


Portable Dissolved Oxygen Meter

Professional portable dissolved oxygen meter, 2 points calibration, selectable the salinity and barometric pressure coefficients, accuracy: 0.2 mg/L.



Features

• Professional portable dissolved oxygen meter is equipped with a backlit LCD display.
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
• Salinity and barometric pressure compensations eliminate the measurement error.

Portable Dissolved Oxygen Meter

• Automatic temperature compensation ensures accurate readings over the entire range.
• Auto-Read function senses and locks the measurement endpoint.
• Calibration due alarm prompts user to calibrate the meter regularly.
• Auto-Power Off effectively conserves battery life.
• Setup menu allows setting the number of calibration points, 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 easy to transfer data to PC.
• Multi-mode power scheme (batteries, power adapter and USB port) ensures that using the
meter smoothly.
