What areas can the handheld portable gas detector detect?
When we need to detect entering some confined spaces, such as reaction tanks, storage tanks or containers, sewers or other underground pipes, underground facilities, agricultural closed granaries, railway tank cars, shipping cargo holds, tunnels and other workplaces, but before people enter, It must be tested, and it must be tested outside the confined space. You must choose a hand-held portable gas detector with a built-in sampling pump
In addition, after entering a closed space, the gas composition should be continuously detected to avoid changes in the concentration of volatile organic compounds or other toxic and harmful gases due to personnel entry, sudden leakage, and temperature changes.
If it is used for emergency accidents, leakage detection and inspection, pump suction type, short response time, high sensitivity and high resolution instruments should be used to facilitate the judgment of the direction of the leakage point.
When conducting industrial sanitation testing and health investigation, the instrument with data recording and statistical calculation and connection with computer functions is very convenient to use. The compound gas detector with pump can meet this requirement.
With the development of the industry, portable multi-gas (composite) detectors are also our new choice. Because the detector can be equipped with multiple gases (inorganic) on the host
The detection sensor has the characteristics of small size, light weight, fast response and multiple gas concentration displays. More importantly, the price of the pump composite gas detector is cheaper than multiple single diffusion gas detectors, and it is more convenient to use.
Selection Notes
A professional gas detector can play its true role only when used in a suitable place, so we should pay attention to the following issues when selecting models:
● Whether the temperature, humidity, and air pressure of the detected site are within the acceptable range of the gas detector, if it exceeds the range, a pretreatment system needs to be installed at the front end;
● Whether the gas concentration in the detected environment is below the normal detection range of the instrument;
● Whether the detection range of the built-in gas sensor of the gas detector meets your detection requirements.
