Handheld Multi Gas Detector Operating Instructions
Model: CM501, CM503,CM504, CM505, CM506, CM507, CM510
Product Overview
Thank you for selecting CM-500 Handheld multi gas detector. The CM-500 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 CM-500 measures the gas
concentration reaching the alarm setting or higher, the data display and alarm functions are activated. CM-
500 is equipped with an RS485 interface for connecting to a computer for remote monitoring to reduce the
risk of exposure to high concentrations of harmful gases and avoid harm to human health. The Handheld
Gas Detector can be used in a wide range of industries, which include paint-related industries, wineries,
related industries of CO
, food industry, laboratory, construction industry, etc.
