About this product
This 4X Gas Detector is extremely durable and measures up to four gases at the same time from a wide range of XCell(R) sensor options including combustible gases, O₂, CO, H₂S, SO₂ and NO₂. Its sensor life of 4 years and run time of 24-hour exceeds the industry average by 71%.
This portable detector is a perfect match for industries ranging from fire fighting to welding, and its digital sensor output makes it unlikely to suffer from RF interference. The unit with MotionAlert, which lets others know if the user has become immobile, the InstantAlert, a manual alarm that alerts others of potentially dangerous situations. This unit is designed to withstand a drop of up to 20 ft and uses less than half the calibration gas as industry average.
