The Eutech Instruments DO 6 is an economy microprocessor-based handheld device designed to measure dissolved oxygen in percentage saturation mode and concentration mode (mg/L or ppm), as well as temperature. The meter features automatic temperature compensation (ATC) and allows for manual adjustments of barometric pressure and salinity to ensure accurate readings across various water conditions.
The document details the complete operation of the device, including inserting batteries and probes, switching between measurement modes, performing calibration using air-saturated water or zero-oxygen solutions, and taking compensated measurements. It also covers advanced setup functions for configuring electrode properties and resetting factory defaults, along with specific care instructions for the probe membrane and electrolyte solution.
| % Saturation Range | 0.00 – 200.0 % |
|---|---|
| Concentration Mode Range | 0.00 – 20.00 mg/L or ppm |
| Temperature Range | -5.0 – 105.0 °C |
| Probe Diameter | Body 12 mm, Cap 16 mm |
| Response Time | 60 seconds to achieve 95% of the reading |
The meter offers measurement in percentage saturation mode, concentration mode (mg/L or ppm), and temperature measurement.
To calibrate for 100% saturation, you must use saturated air or air-saturated water.
The relative accuracy for the mg/L (ppm) Concentration Mode is ± 1.5% of Full Scale.
