Overview

Hospitality Enviro Tech formaldehyde gas leakage detector alarm system gas leakage detector to measure formaldehyde CH2O with pump built in. It adopts 2.31 inch high-definition color screen for real-time display and adopts gas sensors of well-known brands in the industry. It is used to quickly detect the concentration of various gases and the measurement of ambient temperature and humidity, and alarm if the measurement exceeds the limit. It is suitable for detecting gas concentration in pipelines or confined spaces and atmospheric environments gas leakage or high concentration single gas purity where various background gases are nitrogen or oxygen. There are more than 500 kinds of detected gases.
