The ATI A21 Gas Sampler is a now up on GasSensings website and available for purchase.
A21 Gas Sampler
The A21 Gas Sampler is designed to draw a gas sample from a duct, vent stack, enclosed space or hard to reach location and deliver a gas sample to your monitor that can then be located in a more convenient spot. The sensor can then be located more remotely as the pump that is built into the A21 pulls the gas back to the main monitoring device and will ensure reliable gas sample measurement. It also comes with mechanisms that help to ensure reliable sample measurement. There is a flowmeter on the front panel that allows you to adjust the sample flowrate (typically around 500 cc/min). Another important part of this device is a loss of flow detector that alerts when the system notes loss of flow or low flow that could lead to inaccuracies in the sample measurement.
The A21 was designed to be used with the D12 Toxic Gas Transmitter or the B12 Gas Transmitter but can be used with a variety of monitors where you need to pull a sample from a place that is difficult to access. It can be fabricated to be powered by either 120 VAC or 12 VDC.
If you aren’t sure if this device will work with your current set up, contact us and we’d be happy to figure out a detection system that would be best for you!
nice stuff
