SKU: ERANNTEX Portable Four-in-one Gas Detector
In the grand picture of industrial development, there are countless invisible crises. The volatilization of oil and gas at the oil extraction site, the slight leakage of gas distribution pipelines, the escape of harmful gases during environmental monitoring, etc. These potential risks are like invisible sharp blades that may cut through the safety barrier at any time, posing a huge threat to corporate production and personnel life. In this protracted battle against invisible dangers, Shenzhen Eranntex has become a trustworthy partner in the field of industrial safety with its 19-year persistence.
For Eranntex, 19 years is a time of continuous cultivation in the field of industrial gas detection. From an explorer who first entered the industry to a leader today, it has always taken protecting industrial safety as its mission. The Portable Four-in-one Gas Detector developed and produced by it always maintains a high level of vigilance.
This portable four-in-one gas detector has powerful detection capabilities and can accurately identify two-in-one gas detectors, four-in-one gas detectors, four-in-one detectors, multi-gas detectors, multi-in-one gas detectors, multi-function gas detectors, composite gas detectors, carbon dioxide (infrared) CO2, combustible instrument Ex, methane CH4, ethane (infrared) C2H6, propane (infrared) C3H8, non-methane total hydrocarbons CxHy, carbon monoxide CO, hydrogen sulfide H2S, oxygen O2, nitrogen N2, ammonia NH3, chlorine CL2, hydrogen H2, formaldehyde CH2O, ozone O3, nitric oxide NO, nitrogen dioxide NO2, nitrogen oxides NOX, sulfur dioxide SO2 and other common dangerous gases in industrial production. With the help of advanced detection principles such as electrochemistry, infrared, and catalytic combustion, it is like a "sensory system" with keen perception. Even if the gas concentration changes very slightly, it can be detected at the first time and quickly issue an alarm to buy precious response time for enterprises and staff.
Behind the powerful product performance of Eranntex is its strong technical strength. In-depth cooperation with 14 well-known universities such as Tsinghua University and Xi'an Jiaotong University, as well as institutions such as the China Institute of Atomic Energy and the China Inspection and Quarantine Bureau, has injected it with a steady stream of innovative vitality. On the road of technological research and development, Eranntex has never stopped. 100+ patents and research and development results are a strong proof of its continuous breakthroughs and continuous progress. These technological achievements have not only been transformed into more advanced testing equipment, but also provided new ideas and directions for the development of the industry.
