Barograph (mechanical) - Fischer

€1,701.00
Tax included

Aneroid barographs are used to continuously record the atmospheric pressure. The measuring element of the barograph is a 7-fold diaphragm can set, made of a copper-beryllium alloy, which has proven its worth for pressure measurement due to its excellent elasticity. Aging, hysteresis and elastic after-effects practically do not occur.

The temperature influence on the socket set and the transmission system is compensated by a bimetal in the entire measuring range and in a temperature range from -30 to +40 ° C. All axes of the precision mechanical measuring mechanism are stored in stone, which means that the instruments have only minimal static friction.

The barographs are optionally equipped with mechanical or quartz-controlled clockwork, which can be switched from weekly to daily or monthly circulation in a few simple steps. The recording devices are supplied complete with fiber-tip pens and graph paper for an annual requirement.

For use at sea, the Fischer barographs are available with a vibration-damped measuring mechanism.
