Metrology

Some nice little apps helping people working in metrology labs.

HgBarometer for iPhone and iPad

With old style mercury barometers one has to determine the heights of the top and at the glass contact of the meniscus, respectively. Moreover the instrument temperature as well as the gravitational acceleration at the site is needed to estimate the actual barometric pressure. In the past cumbersome tables or laborious calculations were needed to correct the various influence quantities. This app saves you from this trouble.
Because of its toxicity the use of mercury is banned or restricted in many regions of the world. The use of this app is completely safe!
