The tubes for a large number of chemicals have been bought which include: acetaldehyde, acetic acid ,acetone acid mist, acrylonitrile, alcohol, amines , ammonia, benzene, carbon dioxide, carbon monoxide, carbon tetrachloride, chlorine, chloroform, cyclohexane, ethyl acetate, ethylene, ethylene glycol,. formaldehyde, formic acid, hydrocarbons, hydrochloric acid, hydrogen sulphide, mercaptans, mercury vapors, natural gas, nitrous fumes, oil mist, ozone, petroleum hydrocarbons, phenol, phosgene, styrene, sulfur dioxide, sulfuric acid, toluene, trichloroethylene, vinyl chloride.

  • Pulmonary Function Testing Equipment

    This device is extensively used to assess the lung function of workers specially those who have been exposed to dusts and different forms of aerosols and particulates and are at risk to develop occupational lung diseases. It is portable and can be used for on-site monitoring of workers’ pulmonary health. The data is stored in computer, which can be later analysed.

  • Water Testing Equipment

    A number of water testing equipment were procured, which provide an assessment of pollution criteria including pH, conductivity, biological oxygen demand, chemical oxygen demand, ions, trace metals and other parameters.

  • Stack Gas Analyzer

    This instrument was purchased to assess the air pollutant emissions from stacks in the industrial enterprises. Important air pollution parameters like NOx, SOx, CO, CO2, SO2. It also computes combustion efficiency and related parameters.
