Envirotech Stack Monitoring Kit VSS1 PLS

The most common and widely used method (world over) is extractive sample method or Grab sampling technique. Grab sampling technique is also often treated as the reference standard method. Grab Sampling technique is not restricted to a specific pollutant. The same system with different reagents may be used for a variety of pollutants and over different ranges of concentration. Envirotech Stack Monitoring Kit VSS1 PLS is one such Grab Sampler which can monitor Particulate Matter (PM) and any water-soluble gaseous pollutants l ike SO, NO., HF, Cl, , H, S, NH, etc., in industrial emissions from Stationary source I Chimney and Vent.

Utilizing the experience of last 30 years, CPCB in 2015 revised the specifications of the Stack Sampling System & Envirotech has produced a new model Envirotech Stack Monitoring Kit VSS1 PLS with improved features strictly in compliance with latest CPCB guidelines so as to obtain reliable results. Envirotech Stack Monitoring Kit VSS1 PLS overcomes all the drawbacks of previous models.
The operating principle is simple. The Particulate Matter is collected over a filtration thimble. It entraps
and absorbs various gaseous pollutants in suitable reagents, which are analyzed subsequently by simple Wet Chemistry methods to determine the concentration of specific pollutants.

MAIN FEATURES 

Envirotech Stack Monitoring Kit VSS1 PLS

1. Cumbersome Manometer has been replaced with digital pressure cell
2. Designed to determine the velocity of gases also.
3. Measures total quantity/volume of the emissions very accurately.
4. Size and weight of panel has been reduced considerably.
5. Pitot and probe pipe is being provided with extendable arm of 1m each.
6. Calibrated Pitot, probe pipe, thimble holder, nozzles, tools etc, all accommodated in a carrying case.
7. Temperature and pressure at inlet of the rotameter, in order to normalize volume of the sampled gas.
