What is Chlorine?

Chlorine is a greenish-yellow gas, with a sharp bleach-like odor. Chlorine does not occur as a free element in nature, but is abundant in the form of chloride salts. Chlorine is commonly used as a household cleaner and disinfectant. It is also used in water purification and manufacturing of paper and cloth. Chlorine gas was used in WWI, the Iraq War, and the War in Syria for chemical warfare. Chlorine is an oxidizer which may cause or intensify fire. Chlorine can explode if confined and heated under pressure. Chlorine is also very toxic to aquatic life. Chlorine can be cooled or pressurized to its liquid form.

Chlorine Exposure and Health Risks

Chlorine is a potent irritant to the eyes, respiratory tract, and lungs, resulting in burns and redness. Coughing and vomiting are common symptoms of chlorine exposure. Exposure to chlorine can also cause bronchitis or chronic lung conditions. Long term chlorine exposure can cause pulmonary edema resulting in death. Chlorine is toxic and can be fatal if inhaled.

Measuring Chlorine

Chlorine can be measured in the air or in water (dissolved) by units of parts per million (ppm). We have dissolved monitors that measure free, residual, and/or total chlorine. Many of our products have digital communication capabilities for easy monitoring and control. We carry portable, fixed, and dissolved chlorine monitors and kits, and all of our chlorine products can be viewed HERE.
