With so much of industrialization the level of pollution is turning uncontrollable. Whilst products manufactured in industries and factories are simplifying our life, it is impossible to escape the truth that workers are suffering health issue while creating materials to ease our life. Certainly, this is because somewhere the level of gases has become controllable by the manufacturing industries. Be it any work field, manufacturing factory, assembling factory, oil extracting field or all types of mines, harmful gases is taking toll of workers’ health. There has been significant number of death tolls recorded in last decades.

At work place different types of gases are used during the manufacturing of product. Also some toxic gases releases at the time of work. In both cases at times even wearing mask doesn’t work. This is because when the level of such gases crosses its limit, mask fails to protect the workers, but not anymore. A revolution has been fired globally to stop the ill effects of harmful gases on workers.

Calibration gas devices has been developed to identify the level of gases at work places, wherever the possibility of toxic gases are there and then they are controlled by employing different technical measures. Different models of calibration devices are available which specializes in identifying two or more gases at a time, depending on the capacity of the device. Moreover, they are hand held device which makes them easier to use and carry them away if needed. Using calibration gas devices are necessary not only to control health issue of workers, but also to save the earth from constantly increasing temperature.
