Multi-gas detector goes infrared
Crowcon has developed a portable multi-gas detector to combat the problems of flammable gas monitoring in demanding offshore and petrochemical environments
Crowcon has developed a portable multi-gas detector to combat the problems of flammable gas monitoring in demanding offshore and petrochemical environments Joining the top-selling Triple Plus range of instruments, Triple Plus+IR combines user-selected sensors for a range of specific gas hazards with a durable infrared (IR) sensor for flammable hydrocarbons

Emptying hydrocarbon storage tanks, reactors, pipelines or other vessels is dangerous because there is a high risk of creating an explosive mixture if the purging operation is not managed correctly

Unlike other devices for flammable gas measurement, the infrared sensor is unaffected by exposure to "poisoning" compounds such as silicones, or to extreme hydrocarbon levels.
Infrared detection also differs from traditional methods because it does not require the presence of oxygen.
Consequently, as well as personal protection in regular working environments, the Crowcon instrument is suitable for purge monitoring: when tanks which have held flammable liquids are purged with nitrogen, Triple Plus+IR can monitor falling hydrocarbon levels from inside and indicate when it is safe to open the vessel to air.
Three options for flammable gas sensing are available.
A unit measuring 0-100% of the Lower Explosive Limit (LEL) is suitable for general protection; a high-level version measuring gas volume from 0-100% is designed for specialist applications like purge monitoring; and for maximum flexibility, both sensor ranges can be incorporated into one unit.
For simultaneous monitoring of other gases such as oxygen, hydrogen sulphide and carbon monoxide, up to three additional sensors can be specified (two for units with dual-range flammable gas monitoring).
Like all instruments in the Triple Plus range, Triple Plus+IR is designed to withstand extreme physical conditions.
Shock-resistant and sealed to IP65, it has a casing moulded from shatterproof Triax.
Unusually it also floats, making it easy to recover an instrument that has been dropped into water. Request a free brochure from Crowcon Detection Instruments ...
