Vertex provides 8–72 points of continuous gas monitoring and occupies 33 x 19 in. footprint. Sampling points can be placed up to 400 ft from device. Monitoring semiconductor process gases down to ppb levels, Chemcassette colorimetric technology utilizes chemically impregnated paper tape specific to target gas, which reacts to gas with proof of evidence detection that shows change in color. It includes OPC interface that integrates into factory automation system or HMI.
