The PVT properties measuring apparatus of the constant volume method controls the temperature condition at a pressure of 100 MPa to about +70 °C ～ +500 °C to fill the high-pressure vessel with hydrogen gas and then moves it to the low-pressure vessel under a controlled temperature condition at about +60 °C ~ +90 °C. By measuring the pressure of the diluted gas inside the vessel and analyzing the charged mass, the PVT characteristics of the hydrogen can be measured accurately by remote control in the high-temperature and high-pressure range.
●This device consists of PVT property measuring part, constant temperature setting part, data acquisition part and control part.
●Measurable gases are hydrogen, helium and nitrogen, and the supply port is equipped with two-systems of low-pressure (1 MPa or less) and high-pressure (100 MPa).
●The pressure of high-pressure vessel and low-pressure vessel can be measured with an accurate pressure gauge.
●It can be operated remotely and is compatible with increased safety specifications.
