The Miller-Nelson HCS-501 is the standard atmosphere generator referenced in NIOSH and other standard test procedures for evaluation chemical capacity of respirator cartridges.
The Miller-Nelson HCS-501
Starting with a supply of clean, compressed air, the HCS-501 provides your lab with a stream of air that is controlled with respect to flow rate, temperature, and relative humidity. Several HCS-501 versions, scaled for different flow rate ranges, cover an overall range of air flow rates from 2-500 L/min.
We are able to recommend, supply, or fabricate additional devices or custom systems that will allow a client, using the HCS-501, to introduce test contaminants and create a complete chemical challenge test system.
With this technology, we are also able to create custom devices that can provide controlled temperature, humidity, and air (or other gas) flow in response to client specifications. More…
