Today I added a large Utsuki Keiki barometer and a Safonovsky Gidrometpribor M-67 barometer to the instrument collection section of the website. Both are in good working condition. For the month of December, I'm measuring the accuracy of 16 different aneroid barometers on a daily basis by comparing them with readings from my Henry J Green mercury Fortin barometer. The results will be added to the website in early January.
