There are mainly two series of products: gas detectors and gas controllers

KT-603 Portable Single Gas Detector

It is a new type of gas detection instrument developed and produced by Kosa Electronics. This machine adopts high-performance sensor and microcontroller technology, combined with excellent SMD process manufacturing, and has the advantages of good repeatability and temperature and humidity characteristics, long service life, and easy operation. React quickly and accurately to flammable and toxic gases to ensure that you can be immediately alerted in case of danger. It is the most sensitive and alarm capable detector for detecting combustible gases in the industrial field today. Various application environments pose a challenge for gas detectors. In hot, cold, humid, dirty or harsh environments. For example, on oil platforms or mines, the use of instruments is a test. The design of this instrument can adapt to these extremely harsh working environments. ABS explosion-proof and flame-retardant shell, lightweight, easy to carry, and can withstand impact. The shell is made of high-strength engineering plastic and composite elastic rubber, which is waterproof, dustproof, vibration proof, explosion-proof, sturdy and durable, comfortable to the touch, and suitable for detecting toxic, harmful, flammable and explosive gas leakage alarms in various environments. Using OLED high-end display screen, real-time display of detected gas information and parameters, with a good visual experience. The KT-603 combustible gas detector is suitable for industrial sites such as refining and chemical industry, liquefied gas stations, gas, steel, boiler rooms, refueling stations, paint spraying rooms, etc. where combustible gases exist. It is used for gas safety detection and alarm, combustible gas detection and alarm, to ensure the safe operation of workers.
