Testing with the Helmke-Yeich Tumble Drum Tester

The entire unit is first purged in a laminar flow hood or controlled area. The unit incorporates a stainless steel particle counter connection on the exterior of the drum. This connection, with 3/8" ID PVC tubing, to the particle counter enables the operator to sample air inside the drum and evaluate the baseline contamination levels prior to beginning testing. As the Drum spins in the class 100 laminar flow area, background counts will begin to drop in approximately 5 minutes of initial purging, background counts will reach a suitable level to begin testing. These background levels are recorded prior to each test and the product to be tested is introduced and tested for a one (1) minute period. Five (5) additional readings for each product are recorded and averaged. The results will depict the level of contamination that the product will emit to the clean room environment per minute.

Please note: A Particle Counter is not provided as part of the sale of the H-Y Drum Tester. To see Particle counters look at Particle Counters and Testers
