  ZG9 series  
General Introduction
ZG9 series is designed to simultaneously measure multiple gas concentrations in the ambient environment. With long-term data storage, the user can assess the environmental friendliness. When ZG9 series measures the gas concentration reaching the alarm setting or higher, the data display and alarm functions are activated. ZG9 series is equipped with an RS485 interface for connecting to a computer for remote monitoring so as to reduce the risk of exposure to high concentrations of harmful gases and avoid harm to human health. ZG9 series can be used in a wide range of industries, which include paint-related industries, wineries, related industries of CO2, food industry, laboratory, construction industry, etc.
Dual Beam NDIR technology is used to measure CO2 concentration
