The mod. DBS-H2 sensor constantly monitors by display bargraph the hydrogen concentration in the GC oven. In case of leakage at the threshold level and acoustic alarm will starts.
When the upper limit value of hydrogen concentration is reached due a permanent leak the system will stop the DBS gas generator and through a valve (optional) can activate inert gas purge into GC oven.
When lower limit of hydrogen are back to normal the system can allow to restart operations.
