Method 4 Sampling Kit
Method 4 Sampling Kit
EPA Method 4 is used to determine the moisture content of stack gases. A gas sample is extracted at a constant rate from the source. Moisture is then removed from the sample stream and the condensate is measured either by volume or by mass.

Description

The new Method 4 Sampling Kit from Apex Instruments features the SB-6 impinger case. Designed specifically for a flexible Method 4 train arrangement, the SB-6 is crafted with lightweight stainless steel for durability and ease. The raised sides ensure that glassware is protected even in treacherous circumstances. Built with integrated strain reliefs and a leak-proof plastic liner, the SB-6 is the latest innovation in bringing efficiency to stack testing.

Simultaneous Method 2/4 Sampling
Method 4 testing is frequently conducted simultaneously with Method 2, which is used to determine flow rate. The train used for testing flow rate and moisture differs from the standard Method 4 kit. We recommend using the more robust XD-502B console to assist with accurately collecting and recording data. A Method 5 probe with a pitot tip is required to measure flow rate.
