SenseH2 Hydrogen Sensor Installation Location Tips for Battery Rooms

Do you need help determining the appropriate number of SenseH2 hydrogen sensors to safely cover all areas of your battery rooms from the possibility of H2 leaks?  The standard approaches typically used to decide how many sensors are needed for a room include:

  1. The Four Corners method
  2. Locate them above any potential sources of H2 leaks
  3. Or, a combination of the two, depending on the size of the battery room

Hydrogen gas is lighter than air, so it will tend to rise and accumulate in high places.  The Four Corners method involves placing one sensor in each corner of the ceiling where hydrogen may accumulate

Hydrogen sensors can also be placed directly above the potential source of H2 leakage.  As an added level of protection, a combination of both approaches can be utilized.  Your local safety codes will also assist to guide you to which of these method should be chosen.

A hydrogen detection system, which consists of both a sensor and alarm, is the most critical feature of any battery room.


A single unit of the NTM Sensors Hydrogen Detection System can monitor up to two sensors at a time and our Plus model comes with both sensors included.  The system also includes 25 foot (~7.5 m) cables that connect the sensor to the alarm system.  Longer or shorter cables are available depending on the size of the room.

Is a cooling system present in the battery room as well?  No problem, since NTM Sensors has a version of the SenseH2 sensor that is designed to work in the presence of most standard refrigerants.
