PROFESSIONAL TOOL: The gas detector is a device that detects the presence of CO gases in an area, often as part of a safety system. The professional detector can continuously monitor the CO gas concentration accurately in the surrounding environment. This type of equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down.POWERFUL FUNCTION: Sound alarm works when CO gas concentration reaches the level of the alarm. The concentration of alarm value can be freely set. Auto shut off in 10 minutes without any operation. With a wide measuring range, the ambient temperature can be measured in 2 temperature units (C and F).HGIH QUALITYThis CO detector has a large LED backlight screen that allows users to easily cope with harsh environments such as darkness, making it easy to read and free users from time and place constraints. Adopt of ABS engineering plastics with high toughness, wear-resistance and stability, with a low power consumption and high precision.HANDHELD SIZE: The CO gas meter is compact and lightweight, professional designed to fit comfortable in your palmeasy to carry and operate.WIDELY APPLICABLE: The Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion, etc. This type of device is widely used in industry and can be found in locations, such as on oil rigs, to monitor manufacture processes and emerging technologies such as photovoltaic. They may also be used in firefighting. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-DIMEANI official store
