Measurements of lung functions can vary dramatically from person to person. You can easily demonstrate and measure these differences in your classroom with this accurate, easy-to-use, handheld, dry gas meter. It measures vital capacity, tidal volume, and expiratory reserve volume. Students can then calculate inspiratory reserve volume and inspiratory capacity from these values. No calibration needed. The gauge is calibrated to 7 L in 100-cc increments. Just reset the needle after each reading by rotating the dial. Includes 50 reusable mouthpieces, 7/16" ID.
