Portable air samplers used at Los Alamos National Laboratory produce noise levels that make it difficult to conduct classes or tours in their vicinity. If air samplers are shut off during a class or tour, it may not be restarted at the end of the class or tour, preventing detection of low level airborne contamination or the measurement of a more significant release during a later operation. To enable clear communication during tours and classes a timer was designed and constructed that allows an air sampler to be shut o r for a short, fixed duration and automatically restarted. A schematic and parts list is included.
