Product Description

MS104K Portable Muiti Combustible Gas Detector




Data recovery function; in case of mis-operation, it is possible to select partial or full recovery. It is possible to set whether to display the maximum value, minimum value, average value or not. Standard USB charging port, with charging protection function, USB hot-plug supported,and the charging status instrument can work properly. 2100mA high capacity rechargeable polymer battery is adopted, so it is possible to work for a long period of time.

Zero-point automatic tracking; long-term use will not be affected by the zero drift. Multi-level calibration for target points, can ensure the linearity and accuracy of the measurements.




1. Multi-gas made simple, easy to wear, slim and compact
It is possible to simultaneously detect 1 ~ 4 types of gases, and the units can be switched freely .
Units that can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/l.

2. Compact design, easy to use
Handy and durable, the MS104 is intuitive to operate single-handedly using three function keys.
The easy-to-read color display clearly lays out all the information for you. Thanks to its compact and robust construction, the device can withstand even the harshest conditions.

3. Large Data Storage Management, release and documentation in no time
Standard configuration is the data storage capacity for 100, 000 entries.
Real-time storage and fixed time storage are supported, or only the data of the alarm concentration will be stored.
It is supported to use the local host to view, and delete data, and upload the data via USB interface to the computer for data analysis or printing.RS485 communication is an optional configuration.

4. Clear signaling design
The signal system of the MS104K is based on a clear color code: sound & light alarm, vibration alarm, display screen visual alarm.These are also documented in the data logger.

5. Economical Calibration Management
The deviation of the concentration which was detected out by the instrument from the standard gas concentration can be corrected by calibrating the concentration or changing the display coefficients.

6. Inductive charging protects against wear and tear
The MS104K features inductive charging.
This makes it easier to operate and increases the lifespan of the device.
Issues like corrosion and contact problems in the charging cradle are a thing of the past. You can charge (outside of explosion-hazard zones) and measure at the same time.
