Multi gas detectors and monitors are used to detect combustible, flammable, toxic gases and oxygen depletion in oil rigs, mines and other industries. Detectors sound an alarm to operators in the area where leak is occurring, giving them the opportunity to leave. All gas detectors require regular calibration to ensure accuracy of the gas readings. TRUGARD Safety offers a wide range of detectors and professional calibration services to the marine and oil & gas sectors.
