Product Description

MS400 Four-in-One CombustibleGas Detector




In some specific places there are often gas emissions, such as petrochemical, coal, metallurgy, chemical, municipal gas, environmental monitoring and many other places. And some of these gases may be dangerous, such as flammable, explosive or contaminated, then you need to use the gas detector to detect them.
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.
It's 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.



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.
