Low-cost dust monitor for broken bag detection

Snifter A1+ is a low-cost easy to use filter leak detector. This filter leak detector is a direct replacement for the Snifter A1 device. Snifter A1+ can be used for monitoring outlets in a baghouse enabling fast identification of leaking compartments. Commissioning of the device is easy with the convenient auto setup function which identifies normal dust concentration within ten minutes of installation.

The Snifter A1+ dust monitor has two pre-set alarm limits for alarm and alert signals to give plant operators information on leaks and deteriorated filtration performance.

EX models (IECEx and ATEX) are available on Snifter A2 model and upwards.
