Description
SKC 302 Inspector's Model Personal Air Sampler Calibrator Bubble Meter
The SKC 302 Inspector's Model is a soap bubble meter designed to calibrate the flow rate of personal air sampling pumps used in industrial hygiene and occupational safety monitoring. The unit uses the classic soap film displacement method: a soap bubble is generated inside a calibrated glass tube, and the time it takes the bubble to travel a known volume is used to calculate the actual flow rate of the pump under test. This direct volumetric method is a recognized reference technique for verifying pump accuracy in the field or laboratory.

Applications
Personal air sampler calibrators like the SKC 302 are standard tools in industrial hygiene practice, used to verify that personal air sampling pumps are drawing air at the correct flow rate before and after a worker monitoring sample is collected. Accurate flow rate calibration is required by OSHA and NIOSH sampling protocols — if the pump flow is off, the calculated airborne concentration of a contaminant will be in error. The bubble meter technique has been used in occupational health labs and field settings for decades because it requires no electronics and gives a directly traceable volumetric measurement. The SKC 302 Inspector's Model is a compact, portable version suited for field use by industrial hygienists, safety officers, and environmental health technicians. SKC Incorporated, based in Pennsylvania, is one of the leading manufacturers of air sampling equipment and accessories for occupational and environmental monitoring.
This SKC 302 Inspector's Model Personal Sampler Calibrator is in good used condition. The unit has been pulled from a working environment where it was previously in service. Photos show the bubble meter assembly, glass tube, flexible tubing, rubber squeeze bulb, and soap reservoir all intact and undamaged. Normal light handling wear is present consistent with field or lab use. Please view our photo set and contact us if you have any questions.
