Gas Pycnometer Calibration Kit
The most comprehensive gas pycnometer calibration kit available

- Calibration balls (spheres) measured with accuracy of 0.00005” (0.00127mm) using precision micrometers
- Covers over 5 orders of magnitude of volume calibration or verification – 13 different types of balls included
- Two vacuum–suction tools (non-magnetic) for inserting and removal of the large calibration balls, tweezers for
handling small balls
- Micro Calibration Kit included
- Special cloth for cleaning and handling
- Sturdy and lockable box
- Provided as standard equipment with each HumiPyc, but also available separately at a very economical price.

Typical calibration ball sizes supplied with the calibration kit.
The table clearly demonstrates that the maximum error of volume calculations based on the diameter
measurements with precision micrometers is well below the volume detection limits of gas pycnometers.
