Full oil bath ultra-high pressure (69MP) gas adsorption instrument

Full oil bath ultra-high pressure (69MP) gas adsorption instrument

BSD-PHUO full oil bath ultra-high pressure gas adsorption instrument

Product Overview:

Ultra high pressure+full oil bath configuration, 0-50MPa, 0-69MPa optional, 1/2 analysis position optional.

The "full oil bath" refers to the immersion of all gas circuit systems such as valves, pipelines, pressure sensors, and sample tanks into an oil bath at a constant temperature, which improves the temperature accuracy by an order of magnitude compared to air bath constant temperature. It is particularly suitable for evaluating the adsorption characteristics of shale coal with "high pressure, high temperature, low adsorption capacity" above 50MPa.
