Dew point calibration system is a fully self-contained, calibration station capable of producing a flow of air (or nitrogen if you prefer) at a pre-specified range of dew-point temperatures from a minimum of -100 °C to a maximum of +20 °C. It comprises many components including air compressor, air dryer, generator, reference hygrometer, calibration manifold, and housing.

Dew Point Tester is used to characterize the dew point of gas from a newly drilled well or from an offshore production platform. Dew point tester is available in a variety of dew point temperature and pressure ranges. It incorporates a pressure-tight chamber to contain the gas or vapor test sample and valves for controlling gas flow.

Dewatering bag is useful for pumping silt and sediment laden water from a construction site. It is an outlet protection device used to filter sediment from a pump discharge when dewatering a trench or similar excavation in the course of construction. It is designed to control sediment discharge in dewatering operations. It can be easily installed onto the discharge hose. It is portable & easy to remove.
