CSA/ATEX certifications for hazardous environments

Our CSA Class 1 Division 2 (ATEX Class 1 Zone 2) certified devices are approved for use in environments where ignitable gases are present. The inherently low power consumption of Alicat instruments allows for monitoring of flow and pressure in hazardous environments without losing critical features like our multi-parameter display. CSA and ATEX-approved instruments feature locking industrial connectors for power and communications.
