OIL MIST TUBES
The reading is obtained directly off the tube in mg/m3.
NOTE: High water vapor levels can affect accuracy of reading (see note below Table 3).
Ambient Conditions During Sampling
The test result applies only to the sampled portion i. e. to the expanded portion of air. In order to validate
the oil content of the total air in the compressed air system, variations in place and time resulting from
surface adsorption and desorption processes must be taken into account. Such processes strongly
depend on temperature. The measurement must be taken from the same system (machine, compressor
tube line etc.) that will be placed in operation.
Temperature: 10 °C to 30 °C; 50 °F to 86 °F
Humidity: see table 8
Pressure: only for use with de-pressurized air
Interferences and Cross Sensitivities
Vapors of many other organic substances will be indicated too. The sensitivity of indication is different.
Overall Uncertainty
Due to the varying chemical composition within compressor oil types and ambient conditions the
indication shall be regarded only to semi-quantitative.
Storage and Transport
Up to 25 °C (77 °F) and protected from light. Expiration date: see back of package.
Safety Advice/Disposal
For tubes contents the following indications of danger apply:
Indication of danger R: 20/21/22-35-37
Safety advice S: 2-24/25-28.1
Tubes must be kept away from unauthorized persons. For disposal of tubes as waste observe the legal
regulations applicable in the individual country of use.
