Intuitive, ergonomic design

Low resistance expiratory valve

Flexible pMDI adapter

Ensures patients inhale, rather than exhale into the unit

Easily adjustable for each patient's use

Can be seen by patients emerging from the effects of anesthesia

Every In-Check DIAL is individually calibrated to ensure a high degree of accuracy; it's accurate to +/- 10% or 10 L/min (whichever is greater)

Inspiratory flows in the range of 15 L/min to 120 L/ min can be measured

Tested by AEA Technology P.L.C. in the U.K. for accuracy, and has been verified as providing similar resistances to inhaler devices
