Portable gas detectors

Gas detection is one of the most important safety concerns in the oil and gas, chemical, pharmaceutical and shipping industries. Gas detectors are electronic devices (gas detectors) that can detect various types of flammable and toxic gases. Gas detectors can be stationary, portable (personal) or mobile. Usually fixed gas detectors are installed permanently at a selected location and continuously monitor the concentration of combustible gases in the air. Portable gas detectors are usually small, portable devices that can monitor the atmosphere in a confined space. Gas detectors monitor for leaks of flammable or toxic gases to provide early warning of the presence (concentration) of flammable or toxic gases in the air. Riken Keiki gas detectors are certified and safe for everyday use. The GX-3R Gas Monitor is the world's smallest 4-gas detector. Riken Keiki gas detectors can be powered by AA type or lithium-ion batteries. Riken Keiki gas analyzers are certified for use in explosive environments.
