Brief description:
S400 point-type gas detector (different gases can be combined in four-in-one or five-in-one combinations) The instrument is made of high-performance detection components and is manufactured with excellent craftsmanship. The product has functions such as on-site buzzer indication sound, on-site flashing indicator light, and real-time display and monitoring of on-site gas concentration.
S400 multi-function point-type gas detector can convert gas concentration signals in the air into electrical signals for display and remote transmission, using two-wire or four-wire RS485 output mode
