Dust monitor for broken bag detection
Snifter A2 is an advanced filter leak detector. This dust monitor can be used to monitor the operation of a baghouse and alarm the operator when dust levels increase. Snifter A2 supports Sintrol Network connectivity over USB and RS485 interfaces by default. All parameters and settings are user selectable to best suit custom application needs. This device is fully compatible with Sintrol DustTool software.
Auto setup function makes commissioning easy and quick and two independent alarm signals enable easy connectivity.
EX models (IECEx and ATEX) available.
Wireless RF communication available.
