Accurate, Reliable, Hygienic, Affordable - The disposable spirette acts as a hygienic shield for single patient use. The spirette has no sensor elements; it does not perfom a measurement function and therefore no calibration is required.
The barriette is a hygienic barrier that ensures that cross contamination between patients cannot occur. The validated design of the barriette makes sure that the DLCO and FRC valve units are not contaminated by the patient. Two types of barriettes are available, one for DLCO tests and one for multi-breath washout tests.
