We present a manometer designed to measure pressures of 1--20 kbar in temperatures between 4--300 K in cylinder-piston type chambers, with an accuracy of {similar to}100 bar. The manometer is based on pressure-dependent zero-field {sup 63}Cu nuclear quadrupole resonance frequency corresponding to {vert bar}{plus minus}3/2{r angle}{leftrightarrow}{vert bar}{plus minus}1/2{r angle} transition in Cu{sub 2}O. The nuclear quadrupole resonance frequency {nu}{sub {ital Q}} varies linearly with pressure and its temperature dependence is adequately explained by a model of lattice vibrational modes in O---Cu---O bonds. This manometer is particularly convenient for zero or high-field magnetic resonance experiments.
