Lange Caliper Repairs & Calibration

NutriActiva LLC DBA Beta Technology is the manufacturer of the Lange Skinfold caliper, and we provided 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.
