Nicknamed the ‘Navigator’s Choice’ the 225 and 225Q barograph are housed in an aluminium and steel case finished in a coat of white powder paint. The measuring element in this range of Fischer barographs is a set of 7 aneroid capsules, manufactured of a copper-beryllium alloy that essentially eliminate age-hardening, hysteresis, and elastic after effects that could otherwise degrade the accuracy of the instrument. 

Available as either the 225 Barograph with mechanical (wind-up) clock or 225Q with quartz clockwork. The latter of which can be changed in an instant between a daily, weekly or monthly revolution.

The 225Q is compatible with the Fischer 210 chart paper available from our online shop.
