The In-Check Nasal is a portable inspiratory flow meter that monitors both the disease and the response to treatment, through objective assessment of congestion within the nasal passages. Recordings of PNIF (peak nasal inspiratory flow) over several weeks provide detailed information about changes in the airways, and correlate well with both symptom scores and more complicated investigations. 

Accessories / Masks

The standard In-Check Nasal is supplied with a Medium size mask.

Replacement Masks are available in three sizes (Small, Medium Large)

• Small Mask size 3 (single unit) 

• Medium Mask size 5 (single unit) 

• Large Mask size 6 (pack of 20) 

All the above masks are low-odour anaesthetic masks.
