According to different environment and testing requirements, choosing the right and correct gas detector is a must for everyone who is engaged in safety and health work.
The type of gas detector is different depending on the environment.
- fixed:
This is the most commonly used detector in industrial installations and production processes. It can be installed at a specific detection point to detect a specific gas leak. The fixed detector is generally two-body type. The detection head consisting of a sensor and a transmitter is installed on the test site as a whole, and the secondary meter consisting of a circuit, power supply and display alarm device is installed on a safe place for easy monitoring. Its detection principle is the same as that described in the previous section, but it is more suitable for the continuous and long-term stability required by fixed detection in terms of process and technology. They also need to be selected according to the type and concentration of the gas on the site, and they should be installed at the most likely location of the specific gas, such as the most effective height of the sensor installed according to the specific gravity of the gas.
- 2.Portable:
Because of the portable instrument is easy to operate and small in size, it can be carried to different production sites. The I probe can measure temperature, humidity, CO, CO2, calculate the outdoor air percentage, dew point, wet bulb temperature and other information. On-screen prompts and step-by-step indexes guide the user through operation, setup, and field calibration.

- Confined venue:
For example, working places such as reaction tanks, storage tanks or containers, sewers or other underground pipelines, underground facilities, agricultural closed grain silos, railway tankers, shipping cargo holds, tunnels, etc. must be tested before personnel enter, and in confined spaces. Testing. At this time, you must choose a multi-gas detector with a built-in sampling pump. Because the gas distribution and gas types in different parts of the confined space (upper, middle, and lower) are very different. Therefore, a complete confined space gas detector should have a built-in pumping function so that non-contact, sub-site detection can be performed.Multi-gas detection function to detect different gas distribution in different spaces, including inorganic gas and organic gas. It is a portable instrument that prevents oxygen deficiency or hydration and is small in size and does not affect the work of workers. Only in this way can the absolute safety of staff entering confined spaces be guaranteed.
- 2.Open venue:
For example, in the open workshop, this type of instrument is used as a safety alarm, and a diffusion gas detector worn on the body can be used because it can continuously, real-timely and accurately display the concentration of toxic gases on the scene. Some of these new instruments are also equipped with a vibration alarm accessory to avoid audible alarms in noisy environments, and are equipped with computer chips to record peaks, STEL (15-minute short-term exposure level), and TWA (average 8-hour statistical weight ) Provide specific guidance for worker health and safety.
