JBS-420

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 very popular thanks to its performance and flexibility.

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

The robust housing provides IP66 protection, allowing the device to be installed in the most challenging environments. Internal temperature compensation based on a built-in temperature sensor significantly reduces gas concentration reading errors.

The JBS-420 can operate as a stand-alone device or as part of a larger detection system.
