Dissolved Oxygen Calibration
Perform daily calibration for best results. Dissolved oxygen
levels vary with temperature, barometric pressure, and salinity,
so calibration must be performed with consideration of these
factors. It is necessary to adjust the barometric pressure
and salinity values and calibrate the temperature prior to
performing any DO calibration or measurement. For probe
operation, refer to RDO Operation Instructions.
The 450 series can accept one or two calibration values;
typically 100 % using saturated air or air-saturated water, and
0 % using zero oxygen solution. If calibrating for 0 % oxygen,
note that the meter will take several minutes to reach 0 %
saturation value and constant stirring is not required.
100 % Saturation Automatic Calibration
1. Rinse the probe well with clean water. From % saturation
mode, press CAL.
2. The primary display will show the calibration value, while
the secondary display shows the unadjusted value and the
lower display shows the measured temperature.
3. Place the probe in the optional calibration chamber or a
saturated oxygen environment (air or air saturated water) &
wait for the reading to stabilize. Press ENTER to accept.
0 % Saturation Automatic Calibration
1. Rinse the probe well with clean water. From % saturation
mode, press CAL.
2. The primary display will show the calibration value, while
the secondary display shows the unadjusted value and the
lower display shows the measured temperature.
3. Submerse probe in zero oxygen calibration solution and
stir. Wait for the reading to stabilize – this can often take
more than 10 minutes. Wait for the reading to stabilize.
Press ENTER to accept.

1. Rinse the probe well with clean water. From mg/L or ppm
2. The primary display will show the calibration value, while
3. Place the probe into a sample of known oxygen
Temperature Calibration/Manual ATC
1. Press CAL from any measurement, then press MODE.
2. Skip to step 3 for manual ATC, otherwise, dip the temperature

Intended Use, Maintenance & Precautions
These handheld meters use sensors to detect various parameters
for water-based measurements. For routine maintenance
disconnect the power cord or battery, then dust or wipe the
display using a damp cloth. If necessary, warm water or a mild
water based detergent can be used. Immediately remove any
spilled substance from contact with the meter using the proper
cleaning procedure for the type of spill.
• Do not use this equipment in potentially explosive atmospheres.
• Refer to the electrode instructions for use, storage and cleaning.
• Ensure that no liquid enters the instrument.
• Do not use any aggressive cleaning chemicals (solvents or
similar agents).
• There are no user serviceable parts inside. Attempts to
service internal parts may void the warranty.
• WARNING: No modification of this equipment is allowed.
