Designed to facilitate taking a grab sample as per US EPA Method 7C

The sampling equipment consists of a round bottom glass flask (2 L) fitted with a 3-way stopcock. The flask is encapsulated with PE foam and housed in an elegant wooden box. The 3 -way stop cock helps in evacuating the flask, flushing the sample line and collecting the NOx sample in the evacuated flask. Provision is also made to connect a vacuum gauge and a thermometer for measuring the pressure and temperature inside the flask.
