Manufactured for Sherwood Medical (and later bought out by Cheeseborough-Ponds, or vice-versa?). Used a disposable cardboard tube with a mesh that acted as a pneumotach. Photo from an International Biomedical Engineering listing.

Integrating Motor Pneumotachograph, 1958
From New Scientist, November 29, 1956, page 21.
“…it will be necessary to measure their bodily energy exchanges; and this can be done with a modern apparatus called the IMP (integrating motor pneumotachograph). This consists of a light air pump and flowmeter housed in a plastic box, which connects on one side with a mask fitted over the face and on the other with a sample-collecting unit packed in a bag worn on the back. The IMP measures, over a given time, the total volume of air breathed out by its wearer, and from this expired air it automatically takes representative (or integrated) samples. The whole apparatus is so light, well-fitted and comfortable that it can be worn easily during violent exercise or peaceful sleep.
“The IMP was designed by Mr. H.S. Wolff, of the Human Physiology Division of the National Institute for Medical Research, to enable physiologists to study human energy exchanges under conditions ranging from swimming the Channel to bathing a baby. It has attachments allowing the wearer to drink through a tube or blow a whistle; though as yet the IMP cannot measure man’s energry exchanges while he is chatting, smoking, shaving or eating. It is manufactured by J. Langham Thompson.”
Spirometer, Monaghan M403, 1974, Advertisement
The Monaghan M403 used a hot-wire sensor. The readout was digital, the rest its electronic circuitry was likely analog. From: The British Journal of Anesthesia, 1974, Vol 46, No.2, Page 1.
Plethysmograph, 1960’s
Found at Zeepreventorium.org. No description given. Probably from the 1960’s. It may be a volume-displacement plethysmograph and was identified as being manufactured by Fenyves & Gut by Emanuele Isnardi.
Spirometry, Mijnhardt Spirometer, Late 1960’s
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.
Spirometry, Mijnhardt Spirometer, 1960’s
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.
Spirometer, Mijnhardt Vicatest 1a, 1990’s
Found in a listing on www.quoka.de. Probably a volume-displacement rolling seal spirometer from the 1990’s.
Spirometer, Burdick Presto Flash, 1990’s
Found in a DotMed listing. Probably from the 1990’s. The panel size and keyboard layout is almost identical to the Tamarac Presto so they may be the same product from different sources.
Spirometer, Jaeger Flowscreen Pro, 1990’s
Found at MTE Medizintechnik Einhorn
