Handheld Multi Gas Detector Operating Instructions
Model: CM-501, CM-503,CM-504, CM-505, CM-506, CM-507, CM-510
Product Overview
Disclaimer! Please note, dependent on purchased model, some functionalities
differentiate based on sensor configuration.
Thank you for selecting the CM-500 handheld multi gas detector. With long-term data storage, the
CM-500 is designed to simultaneously measure multiple gas concentrations in the ambient environment.
When the CM-500 measures gas concentrations reaching the alarm setting or higher, the data display
and alarm functions will be activated activated. The Handheld Multi Gas Detector can also be used
throughout a wide range of applications, which include, restaurant, beverage, breweries, agriculture,
laboratory, construction, safety and more.
Top Features:
 NDIR (CO2), EC (CO, NH3), and Fluorescence quenching by Oxygen (O2) is used to
measure gas concentrations.
Measurement items: Basic: CO2, CO, PM2.5, PM10, RH, DP, AMB, Barometer
Optional: O2, NH3
