The In-Check DIAL is supplied with a sterilizable plastic mouthpiece and an adapter which enables you to use a pediatric mouthpiece if necessary

The transparent body permits a visual inspection before use, and if required, one-way disposable mouthpiece or a bacterial/viral filter can be used to minimize the risk of cross infection

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)
