ASI - Model ESP-050 Series - Direct Extractive Sample Probe Brochure

The ASI Model ESP-050 Series Direct Extractive Sample Probe ("ESP") is designed to function as a low-flow sample filtering and metering instrument. It is a variant of our originally designed Straight Extractive Sample Tip (aka "SEST"). The ESP Probe prepares the sample from the stack (duct or process) so that it can be measured accurately and precisely by the analyzer (typically a "source-level" analyzer). The ESP-050 probe, connected to an external suction pump (integral to your analyzer or other mechanical or air driven educator pump), extracts a continuous sample from the source gas stream. The gas sample is then passed consecutively through coarse and fine particulate filters (mesh screen, quartz wool, and sintered frit), a preselected glass or metal critical orifice, and is then transported to the analyzer.
