Crowcon Tetra multi gas monitor

Are your workers constantly trashing their gas monitors by leaving them out in the rain, dunking them in water, or dropping them on the ground resulting in costly repairs?

Then the ultra rugged Tetra is your solution. It's a Multi-Gas monitor with a built in internal pump. What separates the Tetra from other Multi-gas instruments is its NEMA 4X construction that prevents dust and water from entering the instrument. In fact the Tetra is sealed so tightly that if it is dropped in water it will float for up to 20 minutes. Just retrieve the instrument and its good to go unlike other monitors that would require a trip back to the factory, resulting in a costly repair bill.
The Tetra also contains a flexible internal assembly, meaning that when the unit is dropped the shock is absorbed by the casing rather than the boards and sensors. If you've ever been unfortunate enough to have this happen to you with other gas monitors, and had to pay for 4 replacement sensors because of sheared off pins and cracked boards, then you'll instantly recognize just how valuable a feature this is.
Now your probably thinking that a Multi-Gas monitor with an internal pump that boasts features that $2,500 monitors don't have has got to be expensive. Shockingly, the Tetra is not only the most rugged Multi-Gas instrument with internal pump on the market, but also one of the lowest priced.
