The Stone Digital Detection Imaging (StoneDDI) device verifies the status of new and in-use diffuser stones. The StoneDDI can calibrate both metal and ceramic cylindrical and spherical diffusers ensuring the stone is within bounds for related testing.
With tightly controlled conditions of airflow, the StoneDDI calculates and determines the pore diameter and permeability.

The StoneDDI operates in a two-test position design to determine the characteristics of the diffuser stone. With a built-in vision system, even the smallest of bubbles are captured for reliable determination of the stone parameters.

This device is fully compliant with ASTM D892, D6082, and E128-99 making it the ideal unit for R&D, QC, and many more applications.

Applications of the StoneDDI Include:
Ceramic spherical diffuser calibration
Metal cylindrical diffuser verification

Key Measuring Parameters:
Pore Diameter: Size in μm
Permeability: Flow in mL/min

The StoneDDI is backed by a comprehensive 1-year warranty, with an option to extend coverage for an additional year upon compliance with the manufacturer’s terms.

The Foam Digital Detection Imaging (FoamDDI) device is a patented and fully automated foamability and foam stability testing apparatus fully compliant with relevant standards, while simultaneously bypassing the operator bias regularly observed in manual analysis. The FoamDDI standardizes the unreliable nature of results from manual vision determinations across tightly controlled conditions of time, flow, and temperature. With an augmented VISION algorithm and high edge contrast, the FoamDDI accurately and reliably determines foam characteristics.

With a patented heating and cooling system, the FoamDDI does not just produce reliable results but also maximizes time and efficiency. The FoamDDI records calculates, and stores data in an easy-to-navigate logic box interface. A single logic box, can also asynchronously control up to four FoamDDI modules, expediting testing in your lab..

This device is fully compliant with ASTM D892, D6082, and D1881 making it the ideal unit for R&D, QC, and many more applications.

Applications of the FoamDDI Include:
Foaming tendency in lubricant systems
Amine foamability in sour gas systems
Glycol foaming parameters

Key Measuring Parameters:
Foamability/Foam Tendency: Height of foam in mL
Foam Stability: Foam collapses in seconds

The FoamDDI is backed by a comprehensive 1-year warranty, with an option to extend coverage for an additional year upon compliance with the manufacturer’s terms.
