GasLab Pro Multi Gas Sampling Data Logger
Operating Instructions
CM-1000
Product Overview
Thank you for selecting the CM-1000 multi gas sampling data logger. The CM-1000is designed to
simultaneously measure multiple gas concentrations through sampling methods.With long-termdata storage,
the user can assess the previous records.When the CM-1000measures the gas concentration reaching the
alarm setting or higher, the data display and alarm functions areactivated. The CM-1000is 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 CO2measurement range: 1%, 5%, 10%, 20% 30%, and 100%
V□Measure CO2,CO, O2, CH4, RH, AMB, DP, ALTI
V□Large LCD for easy reading of gas concentration and temperature and humidity.
V□Audible alarm
V□Data logging with SD card
V□Through 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 along time.
