A container for soda lime crystals is fitted which can be used to absorb carbon dioxide.
The spirometer is designed to minimum resistance to airflow.
This means greater comfort for the subject and more realistic results.
The Spirometer can be used for investigating tidal volumes, respiratory rate, pulmonary ventilation, reserve volumes and vital capacity.
Oxygen consumption can also be measured which is useful in metabolic studies.
A simple lever control enables the subject to be connected either to atmosphere or to the float for recording.
The pen arm corresponds to approximately 0.5 litres.
The two corrugated breathing hoses 0.8m long are provided with two mouthpieces and a nose clip.
The tank is one-piece stainless steel pressing housed in a durable painted outer case.
The float is constructed from lightweight plastic. The float is calibrated 0 to 7 x 0.5 litres and has a metal counterpoise.
Soda lime crystals are not supplied.
