Abstract
High pressures are often measured using the resistance of Manganin wir es. However, the pressure coefficient of resistance is known to depend on temperature. We have measured this temperature dependence by compa ring the output from a Manganin gauge with that of a well calibrated Z eranin gauge and determined a correction factor which enables us to me asure the pressure at any temperature between 150 and 300 K with a tem perature dependent error well below 0.58.
