This is in the industrial device and production process to use more detector. Yi Yang gas detector can be installed in a specific detection point on the specific gas leakage detection. Yi Yang fixed detector is generally two-body type, there are sensors and transmitters composed of the detection head for the integration of the installation in the detection site, there are circuits, power supply and display alarm device composed of the secondary instrumentation for the integration of the installation in the ** place, easy to monitor. Its detection principle as described in the previous section, only in the process and technology is more suitable for fixed detection requirements of continuous, long-term stability and other characteristics. They should also be selected according to the type and concentration of gas at the scene, but also pay attention to install them in a particular gas * may leak parts, such as the specific gravity of the gas to choose the sensor installed * effective height and so on.

Yi Yang portable instruments are easy to operate, compact size, can be carried to different parts of the production, electrochemical detector using alkaline battery power supply, can be used continuously for 1,000 hours; new LEL detector, PID and composite instruments using rechargeable batteries (some have been used without the memory of the sickle-hydrogen or carp-ion batteries), so that they can generally work continuously for nearly 12 hours, so as this type of instrument in the Therefore, as this type of instrument in various types of factories and the health sector is becoming more and more widely used.

If it is in the open occasions, such as open workshop use this kind of instrument as ** alarm, you can use the diffusion gas detector to wear, because it can be continuous, real-time, accurate display of the site of the concentration of toxic and harmful gases. Some of these newer instruments are also equipped with vibration alarm accessories to avoid inaudible audible alarms in noisy environments, and computer chips to record peaks, STELs (15-minute short-term exposure levels) and TWAs (8-hour statistically weighted averages) to provide specific guidance for worker health and **.
