The In-Check DIAL is a hand held inspiratory flow measurement device with a dial top. The DIAL orifices have been designed to simulate the resistance of inhaler devices from the DPI and MDI categories. It enables clinicians to train patients to use more or less inspiratory force, to achieve their optimal flow rate with a particular MDI or DPI device.
Goal: Better lung deposition with less medication waste.



The DIAL can be adjusted to accurately simulate the resistance of popular inhaler devices which include MDI’s and DPI’s such as Turbuhaler®, Flexhaler®, Twisthaler®, Aerolizer®, Handihaler®, Diskus®, Ellipta® and Pressair® among others. The InCheck DIAL enables clinicians to train patients to the proper inspiratory technique considering force and flow rate to achieve improved understanding and ultimately better deposition of the medication being inhaled into the lungs.
The DIAL G16 now categorizes inhalers by resistance and the newly designed scale gives proper feedback on all efforts.
The one-way valved inspiratory mouthpiece allows for multiple patient use and is adaptable for adult or pediatric use protecting both the instrument and the patient from cross-contamination. For increased protection, the DIAL G16 is also available with a BV filter. 

* Custom resistance adapters are available.
