The P/N 1005 is a 4-liter Calibration Bag which is used to calibrate Cemtrex’s portable models which employ sampling pumps. The bag includes a one-way valve and rubber stopper connected to the bag through a sample hose. The bag can be filled with ambient air using a pump (P/N P100) or hand bellows. Then, like the P/N 9905 canister, sample gas taken from a P/N 9106 pure gas bottle can be injected into the bag to produce a mixture of known concentration. The unit’s built-in sample pump can then be used to draw this sample into the unit for calibration. After calibration is complete, the sample can be purged by unzipping the top of the bag. Calibration instructions are silk-screened onto the bag.
