How do you use a Milwaukee dissolved oxygen meter?
“Open Air” Calibration Procedure
- Remove the membrane. Take the membrane off the end of the probe and dry the diode off.
- Zero out the display. Connect the probe to the base unit and turn the unit on.
- Fill the membrane.
- Attach the membrane.
- Let stablize.
- Adjust.
- You are now calibrated.
How do you polarize a probe?
Polarize the probe. The probe must be polarized before use. To polarize a new probe, attach the probe to the meter, connect the meter to a power supply, and wait 30 to 60 minutes.
How do you take dissolved oxygen readings?
Dissolved oxygen levels can be measured by a basic chemical analysis method (titration method), an electrochemical analysis method (diaphragm electrode method), and a photochemical analysis method (fluorescence method). The diaphragm electrode method is the most widely used method.
How often should the oxygen Analyser be calibrated?
Calibrate the Oxygen Analyzer before each use, and when replacing the Oxygen Sensor or the batteries. To ensure accuracy, the Precision Medical Oxygen Analyzer should only be calibrated using 100% Oxygen. Using any other concentration will result in possible inaccurate readings.
How do you clean a dissolved oxygen probe?
What is the correct way to clean the sensor on a dissolved oxygen LDO® probe? Wipe the probe with a soft, wet cloth to remove deposits. For stubborn deposits, use a dilute detergent solution, rinse well, and soak in tap water for approximately 10 minutes.
What is probe polarization?
Probe polarization is essential for stable measurements with the same recurring degree of accuracy. With the probe properly polarized, oxygen is continually ”consumed” by passing through the sensitive diaphragm and dissolving in the electrolyte solution contained inside the probe. >>
