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.

Rechargeable Batteries
Battery message:
‘Battery OK’:
Measurements are possible ‘Battery Low’: The battery needs to be recharged,
measurements are still possible
‘Battery Exhausted’:
Measurements are not
possible
Battery installation:
This device is supplied with Li-ion 18650 3.7V rechargeable battery *3 pcs.
Please confirm whether batteries + polarity are Li ion18650 positive bump specification and install batteries in
the correct polarity. If the battery polarity is reversed, the capacity will be insufficient and the battery life will be
shortened.
Battery charging:
During battery charging, the temperature of the device will rise by 5°C~10°C. At this time, the measurements
of temperature and humidity will be affected by temperature rise. Cause an impact on the accuracy of
temperature when charging, please use a fan to blow towardthe Temperature& Humidity Sensor (○
B) directly
in order to get a compensated balance of temperature and humidity between temperature sensor and
surrounding area. (5V/1A USB adapter charger)
Safety Instructions
Warning: Your safety is very important to us. To ensure use of the device correctly and safely, we would like to

Improper power supply can cause serious damage to the device, or result in injury or death to the user.
Product Care
To ensure you receive the maximum benefit from using this device, please observe the follow guidelines.
1.The maximum capacity of the SD card is 16G.
2.During battery charging, the temperature of the device rises. The temperature and humidity sensors are
affected. At this time, measurements are only for reference. After batteries are fully charged and the device
cools down, measurements are reliable.
3. Repair – Do not attempt to repair the device or modify the circuitry by yourself. Please contact with the local
dealer or a qualified repairman if the device needs servicing.
4. Caution –The CO sensor must be replaced every 3 years.
5.Cleaning – Disconnect the power before clean. Use a damp cloth, do not use the liquid cleaning agent, such
as benzene, thinner or aerosols.
6.Maintenance – Recommend that the user conducts a comprehensive test and calibration every year to
ensure the normal operation of the device.
