Product Description

MS400 Four-in-One
Toxic and Harmful Gas Detector



MS400 Series Gas Detector is up to 4 potential atmospheric hazards including oxygen, combustible and toxic gases, the types of gases for detection are more than 500 types, MS400 is unparalleled in its versatility, capability, and overall value.
Its adopted water-resistant line of portable gas detectors has transformed the market with its matchless array of features.
Continuously monitoring and displaying concentrations of up to 4 gases, the compact and lightweight MS400 was designed and engineered with an extensive host of applications in mind.











1. Specially Designed for Use With Its Internal Pump, Optimized for Your Requirements

The MS400 is equipped with a very powerful internal pump.
It can be connected with hoses of up to 45 meters in length.
This means the pump is only operated when you actually need it. That saves energy, reduces wear and tear, and thereby extends the lifespan of the pump.


2. Compact Design, Easy to Use

Handy and durable, the MS400 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 localhost to view, 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 MS400 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 by the instrument from the standard gas concentration can be corrected by calibrating the concentration or changing the display coefficients.








Gases to be detected

Display mode 2.31-inch high-definition color screen
Communication interface USB (charging and communication), optional: RS485 communication interface
Data storage Standard configuration is the data storage capacity for 100, 000 entries
Protection level IP65
Explosion-proof type Intrinsically safe type
Explosion-proof mark Exia II CT6
Exterior dimensions 160×70×28mm
Weight 300 g
Standard accessories Manual, qualification certificate, warranty card, USB charger (including the data cable), high-grade aluminum instrument case, belt clip, humidity dust filter
Optional items Temperature and humidity measurement function, 1.2 m retractable sampling handle (1-10 meter hose and the standard length is 1 meter), 0.4-meter stainless steel sampling handle (with a dust filter, not retractable), high-temperature sampling and cooling filter handle, high-temperature humidity pretreatment system, multiple humidity dust filter, hanging rope, CD-ROM (upper-level computer communication software)



All the cases require the portable rapid detection of gas concentrations such as petroleum, chemical, pharmaceutical, environmental protection, combustion gas distribution, warehousing, smoke gas analysis, air governance, and so on.
