We are pleased to introduce ourselves as a manufacturer of air pollution monitoring equipment. We take this opportunity to introduce Yash High Volume Air Sampler and Respirable Dust Sampler for the ambient air monitoring and Yash Stack Kit for the flue gas monitoring. Yash H.V.S. can be used for the monitoring of Suspended Particulate Matters (SPM), Sulfur dioxide (SO2), Nitrogen oxides (NOx) and other gaseous pollutants in the ambient air. Yash H.V.S was designed with a view of its usefulness in the field application. Yash H.V.S. is small, light weight sturdy and provided with 24 hour programmable timer to facilitate pthree pre-set time settings. Because of its above feature transportation/shifting of the H.V.S. during the field monitoring is very easy.
