A PVT property measurement apparatus based on the Burnett method has been developed for high pressure hydrogen up to 100 MPa in the range from room temperature to 523K with safety and efficiency in mind, the apparatus was designed for remote operation and computerized data acquisition. PVT property measurements for nitrogen have been performed up to 100 MPa at 353K and they were in good agreement with an existing equation of state(EOS) within ±0.22%. We have finally succeeded in measuring the PVT property of hydrogen up to 100 MPa at 353 K. For these pressure and temperature ranges, the existing EOS for hydrogen is applicable with reasonable accuracy.
