Protean TRAC Low Volume Air Sampler – “goose neck” air sampler.

Low volume air sampler similar in operation to the LV-14M or other goose neck air sampler.  These were originally built to operate with Protean automatic sample counters and have a smart head that can be loaded into the Protean sample counter and transmit all the sample data automatically.

For everyone else, you would operate it just like you do a LV-14 or any other low volume air sampler. Put a sample head on there (or use the one supplied) and take the start and end time and flow rates to calculate the total flow.  The unit will give you that automatically by reading the instrument panel.  These also have long hoses that can be strung to remote areas of sampling interest while the cart sits nearby.

These can be easily wheeled anywhere.  They are in excellent condition and are relatively unused.
