ACCURACY STATEMENT
Every In-Check DIAL is individually calibrated to ensure a high degree of accuracy. Inspiratory flows in the range of 15 l/min to 120 l/min can be measured. In-Check DIAL is accurate to +/- 10% or 10 l/min (whichever is the greater), and has repeatability of +/- 5 l/min.
In the In-Check DIAL has been tested by AEA Technology www.aeat.co.uk for accuracy, and has been verified as providing similar resistances to inhaler devices.
The In-Check DIAL has been calibrated using an ATS pulmonary waveform generator. In-Check DIAL complies with the AUS/NZ standard for back pressure in flow meters.
