The new Environmental Sampling Unit (ESU) from Crowcon is used for monitoring high-density, toxic gases such as chlorine and sulphur dioxide where positioning a conventional sensor is not practical. The ESUâ€™s chamber is fitted with an Xgard detector, and an electric fan draws air into the chamber via a sampling pipe. The ESU is ideal for monitoring large enclosed areas.
