Frequently Asked Questions

What is the gas displacement technique used by the Pycnomatic ATC?

The gas displacement technique measures sample volume by determining the volume of inert gas displaced by the solid material, enabling accurate density calculations regardless of sample shape or porosity.

What are the advantages of the Peltier cooling system?

The Peltier cooling system provides superior system stability and precise temperature control without mechanical refrigeration, reducing vibration and ensuring consistent measurement conditions.

Can the sample chamber size be customized?

Yes, standard chambers are available in 20, 40, and 60 cm³ sizes, with optional configurations available from 4-100 cm³ to accommodate various sample sizes.

How often should calibration be performed?

Calibration using certified stainless steel spheres should be performed according to your laboratory's quality assurance protocols, typically annually or per ISO 1183 standards.

What software is included with the instrument?

Windows-based software is provided for data recording, analysis, and archiving, enabling comprehensive documentation of density measurement results.
