Application of portable gas detector in various fields
The application of portable gas detectors in various fields, as we all know, portable gas detectors are small in size, easy to operate, and can be carried to different production departments. The electrochemical detector is powered by alkaline batteries and can be used continuously for 1000 hours. The new LEL detectors, PID and composite instruments use rechargeable batteries (some have adopted memoryless nickel-metal hydride or lithium-ion batteries), so that they can generally work continuously for nearly 12 hours, so as such instruments in various factories and Applications in the health sector are growing.
If this type of instrument is used as a safety alarm in an open place, such as an open workshop, you can use a diffusion gas detector that you wear, because it can continuously, real-time and accurately display the concentration of toxic and harmful gases on site. Some of these newer instruments also come with a vibrating alarm accessory - to avoid audible alarms in noisy environments, and install a computer chip to record peaks, S (15-minute short-term exposure level) and TWA (8-hour statistical weighted average) - provides specific guidance on worker health and safety.
In addition, after entering the confined space, it is necessary to continuously detect the gas components in it to avoid changes in the concentration of volatile organic compounds or other toxic and harmful gases caused by personnel entry, sudden leakage, and temperature changes. If it is used for emergency accidents, leak detection and inspections, it should use pump suction, short response time, high sensitivity and resolution instruments, so that the location of the leak point can be easily determined. In the case of industrial hygiene inspections and health surveys, it is very convenient to apply instruments with functions such as data recording and statistical calculation, and can be connected to a computer.
At present, with the development of manufacturing technology, portable all-in-one gas detector is also a new choice for us. Since this detector can be equipped with multiple required gas (inorganic/organic) detection sensors on one host, it has the characteristics of small size, light weight, fast response, and simultaneous multi-gas concentration display. More importantly, the price of the pump-suction composite gas detector is cheaper than that of multiple single diffusion gas detectors, and it is more convenient to use. It should be noted that when choosing this type of detector, choose an instrument with the function of switching each sensor individually to prevent the damage of one sensor from affecting the use of other sensors. At the same time, in order to avoid the blockage of the suction pump due to water intake, it is also safer to choose an instrument designed with a smart pump with a pump stop alarm.
