DOM30AY Portable Dissolved Oxygen Meter

Description

1.Large LCD screen with controllable white backlight.
2. Built-in microprocessor chip has Intelligent functions such as auto calibration, ATC, data storage, function settings, auto
diagnosis, auto power off, and under voltage prompt, etc.
3. DO mode has functions of ATC, auto salinity compensation and manual pressure compensation
4. New structure polarography DO electrode can measure temperature, salinity and dissolved oxygen simultaneously,
equipped with special DO electrode calibration sleeve, only need 3~5 minutes for polarization.
5. Combined diaphragm cap makes it extremely convenient to replace the sensitive membrane just by screwing the new cap to
the electrode.
6. Grade IP57 and equipped with suitcase for outdoor purpose.
