HiYi MS400 Portable Gas Detector
4 in 1 | Internal Pump | Large Data Storage
Clearance measurement was never this easy and convenient!
The MS400 measures up to 4 gases, including toxic, flammable gases and vapors, and oxygen all at once—either in pump or diffusion mode.
Innovative signaling design and handy wizard functions ensure complete safety throughout the process.
- ★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.
- ★Built-in pump-suction type measurement, built-in water vapor, dust filter, so as to prevent the damage of sensors and instruments due to the water vapor and dust.
- ★Rich human-machine interface
2.31-inch high-definition color screen, display the information such as real-time concentration, alarm, time, temperature, humidity, storage, and so on.
- ★Function of large-capacity data storage (capacity can be customized), multiple storage modes are supported, and RS485 communication is an optional configuration.
- ★High temperature gas detection (optional)
The optional high-temperature sampling and cooling filter handle or high-temperature high-humidity pretreatment system will be possible to detect the smoke gas at the temperature of 400 ℃. The detection for the gases at higher temperatures can be customized.
- ★It is possible to switch among three display modes .
- ★Graphical display, and use the form of curve to reflect the trend of gas concentration changes in a certain period of time.
