Why Insatech for Crowcon portable detectors

ATEX, IECEx and MED certified
Crowcon portable detectors carry ATEX and IECEx certification for use in classified hazardous areas - and selected models including the T4 and T4x carry MED certification for use on EU-flagged vessels. We supply the correct certified variant with full documentation.

Personal and area detection covered
From single gas detectors for individual worker protection to multi-gas units for confined space entry and portable area monitors for temporary worksites - the Crowcon range covers the full scope of portable gas detection requirements.

Coverage of marine and offshore gas hazards
Hydrogen sulphide, carbon monoxide, oxygen depletion, flammable hydrocarbons - the gas hazards most commonly encountered during shipboard maintenance, tank inspections, and offshore confined space entry are all covered within the Crowcon range.

Zone 0 approved options
For confined space entry into cargo tanks, storage tanks, and other Zone 0 classified spaces on board vessels and offshore platforms, the Crowcon T4x provides Zone 0 approved personal detection - one of the few portable detectors in the market carrying this classification.
