The level of moisture in certain process streams can be critical to successful plant operation. Confidence in the accuracy of moisture measurement devices is greatly enhanced by regular calibration, using gas transfer standards. Proton offers such calibration standards at moisture concentration levels as low as 1 PPM.

| Service To Automotive Industries |
Speciality gases are uniquely placed to supply the complete range of gases and gas mixtures required by Indian Automotive Industry. These products are used as standards to determine performance in exhaust emission analysis evaporative loss testing field surveillance, engine performance and efficiency and crank case emission. The range extends from stable traceable mixtures for calibration of sensitive emission analysis equipment to high purity air fuel gas. Nitrogen is used as carrier gas for such equipment.

| Service To Petrochemical and Refineries |
Calibration gases required by Indian refineries and petrochemical industries are complex and varied. We aim to supply a quality product whatever the application. Investment in new plant, equipment and analytical facilities ensures that customized calibration standards are supplied as per specification on time. Utilization of just in time principles of manufacture has established the most efficient manufacturing structure to reduce actual lead times significantly.
| Process steam calibration |
Blends of Hydrocarbon are prepared in the gaseous phase for the accurate and repeatable calibration requirements. Most are supplied as certified standards. Since the potential range of blend is almost infinite most are prepared to customer order.
The poisonous effect can be divided into three main groups
- Asphyxiates - which are effecting the oxygen up take viz CO2, N2 CO and HCN.
- Irritating Gases - Gases which are irritating the organism viz NH3 CL2.
- Central Effective Gas - which are affecting the central nervous system viz different hydrocarbons / aromatics.
Maximum Exposure Level of all the toxic gases is measured as threshold limit value TLV. TLV is the time weighted average concentration of an airborne substance that represents the condition under which generally believed, all workers may be exposed to a normal eight hours five day week without suffering adverse effect. |
