XC-623 Series Console

Manual Sampling of Gaseous Pollutants

Overview

The Apex Instruments XC-623 Series Console is a versatile and dependable manual gas sampling unit designed for collecting gaseous pollutants from stationary sources such as stacks, flues, vents, and pipes.

This console is commonly used for EPA Methods 6, 26, and VOST (Methods 0030 & 0031) but is also suitable for other methods requiring precise volume measurements and constant sample flow rates between 300 ccm to 4 LPM.
