The assessment of a new bellows spirometer against a water spirograph showed slight alinearity, minimal overestimation of FVC (2.9%) as well as of the ratio FEV1.0 FVC (4.8%). The main advantages of the instrument were: lightness, easy operation, ruggedness and low cost; its greatest use may be in large scale field surveys.
