Lange Caliper Repairs & Calibration

NutriActiva LLC DBA Beta Technology is the manufacturer of the Lange Skinfold caliper, and we provide repair and calibration services.  

How Often Should the Lange Skinfold Caliper be Calibrated? 


  • To ensure the Lange caliper has calibrated pressure, the springs should be replaced every 5 years or after 10,000 uses, whichever comes first. 
  • The Lange caliper factory calibration for the dial reading is +/- 1.0mm. Calibration service is not required if it falls within that standard. It can be tested with the 5-step calibration block.

If you have a 5-step calibration block you can email us the following:

  • Pictures showing the reading at each of the 5 increments
  • Picture of the serial number on the bottom side of thumb handle 
  • A copy of your original purchase invoice, if available.  We can only certify the pressure with a proof of purchase date.
