Spec Sheet for HJ-113 and HJ-112

Each manual has a specification sheet that lists all the specs for each unit so let’s study them.



The differences between the two units are:

  • the differences in buttons previous mentioned.
  • the Omron HJ-113 calculates the amount of fat burned and the Omron HJ-112 does not.
  • the Omron HJ-113 has an operating humidity specification and a “Storage Temperature/Humidity/Air Pressure” and the Omron HJ-112 does not.
  • the dimensions of the two units are different.  The Omron HJ-112 is more oval shaped than the Omron HJ-113.  Both units are the same thickness.
  • the Omron HJ-113 is 0.11 ounces lighter than the Omron HJ-112 with battery included.

This table sums up the differences.  Bottom line – you can buy the Omron HJ-113 for less than the Omron HJ-112 on Amazon.
