Casella CEL’s TUFF range of Personal Air Sampling Pumps, a rugged pump for use in harsh monitoring environments, has gained ATEX (and IECEx) Intrinsically Safe approval for use in flammable atmospheres meaning they can now be used in hazardous plants and production sites where there is a potential risk of explosive dust or gas.

Designed to European IP54 standards (protected from dust and splashing water), the TUFF also differs from ordinary handheld pumps in that it is said to be the only Personal Air Sampling Pump to receive certification to ‘M1’ classification required for mining applications, allowing it to be safely used underground without the need for a hot work permit.
