The GM Instruments Peak Nasal Inspiratory Flow Meter is a lightweight, compact and simple way to inspect the patency of a patients nose.

Our PNIF Meter has a number of benefits:

  • Helps Diagnosis of nasal obstruction and the assessment of response to nasal provocation
  • Measures nasal inspiratory flow for assessing nasal airway patency
  • +/-10% of reading or 10 L/min flow (whichever is the greater), with repeatability of +/-5%
  • In normal use it is expected that the PNIF unit will remain operational for 2 years
  • Very easy product to use and to clean
Our own brand Peak Nasal Inspiratory Flow Meter can be used to quickly assess the patency of a patients nose. It is used along with either a disposable or reusable mask, both of which are available in either in a range of sizes (See Options Tab). A medium disposable mask is included with the unit when delivered.

It uses a variable diameter tube calibrated directly in litres per minute (Lpm), along with a low inertia indicator ring, whose position after an inspiratory manoeuvre clearly indicates the maximum flow achieved.

These product consumables are also available:

  • Disposable PNIF small masks
  • Disposable PNIF medium masks
  • Re-usable PNIF small masks
  • Re-usable PNIF medium masks

Units can be ordered on a one off basis or in larger quantities, when discounted prices will apply.

Plus/Minus 10% of reading or 10 L/min flow (whichever is the greater), with repeatability of plus/minus 5%.
