The S400-H is an intelligent multi-functional gas detection instrument. The instrument is manufactured by combining high-performance detection components and computer micro-control technology with advanced fully automatic surface mounting process. The product has functions such as on-site buzzer indication sound and on-site flashing indicator light, and displays the gas concentration at the monitoring site in real time.

The S400-H split-type gas detector is used in special environments where the instrument and the probe need to be separated. The separation distance between the probe and the display instrument can be up to 10m. Its basic functions: signal transmission, LED light and relay alarm functions can also be achieved.
