Gas Analyzer



Choline is a caus­tic poi­sonous gas of a green col­or, which is only en­coun­tered in na­ture in a gaseous state in com­pounds with oth­er gas­es. It has a sweet smell and weighs more than air. It does not burn in a nor­mal state, but at in­creased tem­per­a­ture, chlo­rine re­acts with hy­dro­gen, which may cause an ex­plo­sion and the re­lease of phos­gene gas. Chlo­rine is very poi­sonous, and even a low con­cen­tra­tion of it in the air can be fa­tal.

Caution: Chlorine has a high electronegativity and a high electron affinity, the latter being even slightly higher than that of fluorine. The affinity of chlorine for hydrogen is so great that the reaction proceeds with explosive violence in light.

Aditional Information

Cl2 Poisoning

Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It becomes a liquid at −34 °C (−29 °F). It has a choking smell, and inhalation causes suffocation, constriction of the chest, tightness in the throat, and—after severe exposure -edema- (filling with fluid) of the lungs. As little as one part per thousand in air causes death within a few minutes, but less than one part per million may be tolerated.

Note: Due Sensors are factory calibrated and cetification is 24 months valid once the calibration process is performed, we don't have a stock, we can sell you any sensor only as required.
