1.Product introduction
1.1product description
Potentially toxic or explosive gases may be used in the production process of many industries.
RS-MG41-1 is an intrinsically safe composite detector developed by our company for
environments containing explosive or toxic gases. The instrument uses a natural diffusion method
to detect the gas and an electrochemical combustion gas sensor. It has excellent sensitivity and
excellent repeatability. The product can detect four gases: oxygen, flammable gas, carbon
monoxide, and hydrogen sulfide. The product can store up to 130,000 pieces of test data, and the
historical data can be viewed at any time with the software.
The product is easy to use and maintain, and meets the requirements of industrial site safety
monitoring for high reliability of the equipment. The housing is made of high-strength engineering
plastics and composite non-slip rubber, which has high strength and good feel, and is waterproof,

6.4 Clear device data
Click "Device" in the toolbar, and click "Delete device storage data" in the drop-down menu to
clear the device data. After clearing, the software prompts "Delete cleared successfully".
7.Gas calibration
Due to the normal loss and aging of the sensor during use, the instrument needs to be
calibrated after a long period of use.
To calibrate the equipment, a special calibration hood is required for calibration, as shown in

RS-MG41-1 Composite Multi-Gas Detector User Manual V1.0
Shandong Renke Control Technology Co., Ltd. www.renkeer.com
17
the figure below.：
* Please contact the manufacturer for specific calibration methods
8.Charging function description
When the power is less than 10%, the device issues an alarm (acoustic and visual vibration)
every two minutes until the device is turned off.
When the device is off, connect the charger to the portable detector and the other end to the
AC220V AC power supply. When the detector is fully charged, the battery capacity will be full
and it can be used normally.
9.Precautions
1. Prevent the machine from falling from high places or receiving severe vibration
2. In high-concentration gas environment, the machine may not work properly
3. Please use the detector strictly in accordance with the instructions, otherwise it may cause
inaccurate test results or damage the product
4. This product cannot be used or stored in the environment containing corrosive gas
5. If the device has not been used for a long time, please warm up and aging for 10 minutes before
using it again.
6. To ensure the accuracy of the test, the machine should be calibrated regularly, and the test
period should not exceed one year.
7. In an explosive gas environment, do not remove or replace the battery pack, and do not charge
the battery pack.
