Operating Instructions
CM-1000
Product Overview
Thank you for selecting the CM-1000 multi gas sampling data logger. The CM-1000 is designed to
simultaneously measure multiple gas concentrations through sampling methods. With long-term data storage,
the user can assess the previous records. When the CM-1000 measures the gas concentration reaching the
alarm setting or higher, the data display and alarm functions are activated. The CM-1000 is equipped with
an RS485 interface for connecting to a computer for remote monitoring. The Multi Gas Sampling Data
Logger can be used in a wide-range of industries and applications.
Features:
V □ Options for CO measurement range: 1%, 5%, 10%, 20% 30%, and 100%

V □ Large LCD for easy reading of gas concentration and temperature and humidity.
V □ Audible alarm
V □ Data logging with SD card
V □ T hrough the RS485 interface connection, multiple CM-1000 units can be connected to the back-end
computer system as a security monitoring application.
V □ Built-in LCD back light for easy reading in the dark.
V □ This device is supplied with Li- ion 18650 3.7V rechargeable batteries, can be used for a long time.
