JBS-420 Gas Detector

 

The JBS-420 gas detector is the ideal solution for monitoring concentrations and detecting gas leaks.

Due to its small size, it can be installed in hard-to-reach places. The JBS-420 is a versatile device that is popular for its performance and flexibility.

The device allows customization of sensors according to customer needs. JBS-420 is equipped with a wide range of communication interfaces. Our gas detector provides wireless communication via mobile devices as standard.

The solid design of the case provides IP66 protection so that the device can be installed in the most difficult environments. Internal temperature compensation based on the built-in temperature sensor allows to significantly reduce the error of gas concentration reading.

The JBS-420 can operate as separate device but also as part of a larger detection system.

 

Device features:

  • Flexible choice of sensors
  • Possibility to mount 1 or 2 sensors
  • RS485, BLE interfaces, 2 relay outputs and physical buttons
  • Simple and intuitive application for monitoring and managing the detector
  • Bright, multi-color status indication
  • Internal electronic ambient temperature compensation
  • Built-in buzzer
  • Solid and durable design
  • Compact size and low weight of the device
  • IP66 protection
