Anton Paar provides density measuring cells which operate at pressures up to 700/1400 bar (10,000/20,300 psi) and temperatures between -10 °C and + 200 °C (14 to 392 °F). The high pressure cells DMA HP and DMA HPM
can handle both gaseous and highly viscous samples.
They are ideal instruments for investigating samples with high melting points and determining equations of state of liquids and gases under extreme temperature and pressure conditions. A repeatability of up to
0.00001 g/cm3 can be attained.
