Description
The Crowcon XgardIQ is the most intelligent fixed gas detector, which increases safety by minimising the time operators must spend in hazardous areas.
The Crowcon XgardIQ is a versatile transmitter and gas detector and has a wide range of featuers that protect engineers and support facilities managers of oil, gas, chemical & petrochemical plants to name a few. The XgardIQ is available with a variety of sensors for flammable, toxic, oxygen or fixed H2S gas detection.
