Description
T3 Multi Gas Detector is designed with the user in mind, the top mount display, full function data and event logs, audible, visual and vibrating alarms deliver top end performance in a small and lightweight package. Gases include the most common 4 (carbon monoxide, hydrogen sulfide, oxygen and flammables) plus ammonia, ozone, sulfur dioxide, hydrogen filtered carbon monoxide, hydrogen cyanide, other flammable gases and IR carbon dioxide (for safe areas only)
Other ranges and alarm levels are available on request. Each gas channel can have two instantaneous alarm levels set, Toxic channels also have Time Weighted Average alarms. Flammable gas calibration is available for methane, propane, butane, pentane, hydrogen and ethylene as standard.
