着量測定装置。[Scope of Claim for Utility Model Registration] A sample cell containing a sample to be measured is filled with a vapor-phase adsorbate, and a predetermined portion of the sample cell is cooled by immersing it in a refrigerant in a Dewar bottle. The device for measuring the amount of physical adsorption of the adsorbate by the sample to be measured includes a sensor for detecting the level of the refrigerant in the dewar bottle, an elevator device for driving the dewar bottle up and down, and a detection result of the sensor. and a control device for controlling the drive of the elevator device so as to maintain a constant level of the refrigerant relative to the sample cell.

。 The sample cell containing the sample to be measured is filled with vapor-phase adsorbate, and the sample cell is cooled by immersing up to a predetermined part of the sample cell in a refrigerant in a dewar bottle, and the adsorbate is absorbed by the sample to be measured. The device for measuring the amount of physical adsorption includes a sensor that detects the refrigerant liquid level in the dewar bottle, an elevator device that drives the deuwar bottle up and down, and a refrigerant liquid level relative to the sample cell based on the detection result of the sensor. a control device for controlling the drive of the elevator device so as to maintain a constant position; and an alarm device for detecting that the dewar bottle has reached a preset upper limit position by driving the elevator device and issuing an alarm. An adsorption amount measuring device characterized by:
