Helium Porosimeter

Manufacturer: Vinci Technologies
Model Number: HEP-P

The Helium porosimeter is a gas expansion porosimeter based on the Boyle's and Charles' law expansion of helium gas and is used for direct grain volume and pore volume measurement in auxiliary cell at isothermal conditions. Subsequently, porosity and grain density can be derived from the direct measurements. A data acquisition computer allows for data logging and calculation of parameters and also calibration data. The instrument measures grain volume of plug samples of 1" and 1,5" diameter. An optional full diameter matrix cup can be added for determination of grain volume of whole diameter core samples. On the helium porosimeter each sample matrix cup is interchangeable and is provided with stainless steel calibration check plugs. An auxiliary core holder for plug and whole diameter core samples can also be used to measure pore volume at ambient or overburden pressure.
