  • Product typeOther Appliances
  • Measures dissolved oxygen from 0.00 to 50.00 mg/L for precise water quality analysis
  • Stores up to 750 data sets internally for extended field sessions
  • Transfers readings via USB or Bluetooth for convenient reporting
  • IP67-rated main unit resists splashes and brief submersion
  • Auto temperature, manual pressure and salinity compensation maintain accuracy across conditions

Portable Dissolved Oxygen Meter

The VEVOR dissolved oxygen meter measures 0.00-50.00 mg/L dissolved oxygen and 0.0-500.0% air saturation with ±2% accuracy. It includes a 13.1 ft electrode cable and stores 750 data sets. This kit suits pond managers and field technicians who need portable water-quality logging.

Bluetooth and USB Data Limits

Data transfers via Bluetooth to a mobile app or by USB cable to a computer; no Wi-Fi direct connection is provided. The electrode cable is fixed at 13.1 ft, so sampling depth cannot exceed that length. The meter operates in 0-50 °C ambient conditions with up to 50 °C electrode temperature.

±2 % Accuracy Decides Suitability

The single specification that determines fit is the ±2% accuracy for dissolved oxygen and air saturation readings. If your application requires tighter tolerance than ±2%, this meter will not meet the requirement.

Questions about this item

Should I pick the 0.00-50.00 mg/L range or the 0.0-500.0% saturation range for my testing?

The meter measures both simultaneously — dissolved oxygen in mg/L and air saturation in percent — so you do not choose one over the other; each reading appears on the display together.

What does the ±2% accuracy figure mean when I am testing a pond on site?

It means the dissolved oxygen reading will be within two percent of the true value, and the temperature reading within ±0.3 °C, provided you set the pressure compensation between 600 and 1100 hPa and salinity between 0.0 and 40.0 g/L.

How does the Bluetooth and USB data transfer limit the number of readings I can offload?

The unit stores 750 data sets internally; both Bluetooth and USB can export the full 750 records, so the interface does not cap the transfer — only the onboard memory does.
