“This spirometer, recently introduced to this country, is a direct measurement dry spirometer of 6 litres capacity which functions on a metal sliding cylinder/rubber rolling seal principle.
“The instrument uses an A-4 size recording paper with space provided on the paper for entering essential test and test subject information.
“The Vicatest-2 has an integral microcomputer which provides instantaneous digital display of essential respiratory parameters – FVC, FEV1, FEV1%, MVV, PEF, FEF, FMF and FMFT, thereby eliminating manual calculations. It can be supplied with an integral printer module and a print-out unit, as optional accessories, which at the tough of a button give a print-out of all parameter which can be attached to the recorded expiratory curve, thus giving a complete and permanent record of the test.”

A rolling seal volume displacement spirometer. Found on an European Ebay listing.
Found at Zeepreventorium.org. Described as a Mijnhardt spirometer from the late 1960’s. Given the gauges and columns at a guess this system probably performed helium dilution FRC tests as well as spirometry.
Found at Zeepreventorium.org. Described as a Mijnhardt spirometer from the 1960’s. Appears to be a water-seal spirometer. Kymograph paper appears to be stretched across two rollers.
Found in a listing on www.quoka.de. Probably a volume-displacement rolling seal spirometer from the 1990’s.
