This detector is ideal for freezers or hard to access areas, as the aspirated detector can draw a gas sample from up to 20m away while the sensor element is placed in an easy-to-access environment.

The perfect carbon dioxide detector for freezers or harsh industrial refrigeration plants

The TOCSIN 750S aspirated gas detector from IGD is an addressable aspirated gas detector which allows you to provide gas detection in areas otherwise difficult to access, or harsh to normal diffusion sensors. Featuring our unique piezo pump technology, our aspirated gas detectors have virtually no moving parts and are virtually silent in operation. Thus, reducing maintenance requirement and providing near continuous gas detection up to 20m away.
