Gashawk™ Personal Gas Monitor

Gas Detection Done Better


The new GasHawk from Trolex is the world’s foremost personal gas detector for mining, with up to 7 days battery life even with infrared sensors installed. GasHawk is tough, reliable and easy to use, which provides the best protection available to your people.

With the new #supportmining offer on consumables as part of the launch, we will supply the sensors for GasHawk PGM at cost price to all of our customers, which means our customers save on average an 80% discount compared to our competitors.

This is in response to the tough times facing the industry and the need to control cost levels. The cost of ownership on the GasHawk will be around 50-60% less than inferior competitor units.
