TPK 100i – Critical Flow Controller
The Critical Flow Controller TPK 100i is designed to provide (and document) all of the critical parameters employed in the delivered dose uniformity (DDU) testing and aerodynamic particle size distribution (APSD) measurement of Dry Powder Inhalers (DPIs). It can also be used as a Breath Actuation Controller (BAC) for testing Metered Dose Inhalers (MDIs) with Spacers/Valved Holding Chambers (VHCs) and breath-actuated MDIs in accordance with Ph.Eur. 0671 and USP Chapter <1602>.
Simplified workflow with user-guided test set-up
Automatic calculation of test duration from volume and flow rate
Device (inhaler) flow resistance calculator
User warned if sonic flow conditions are not met
Extensive data output options
