Stratum Reservoir - Model DHP-200-M -Digital Helium Porosimeter
Measures both grain volume using internal matrix cup for samples and directly pore volume using ext. core holder. Porosimeter have several reference volumes (VI) that can be combined in order to adjust the ref. volume to achieve optimal calibration results for diff. sample sizes.

- There is also possibility to connect an external tank to increase the ref. volume e.g. for measuring whole core.
- Matrix cups with different internal diameter can be used.
- Pneumatic open/close function for matrix cup for rapid loading and off-loading of samples, gives a high through-put.
- When using external core holder for pore volume measurements, helium is injected from both ends of the sample in order to reduce the time to reach equilibrium.
- The instrument has 2 pcs. in-line temperature sensors with display to monitor the T1 (@V1) and T2 (@V2). It is vital that the temperature at calibration is the same during the measurements, to secure accuracy and repeatability.
