Peak Flow Meter
Peak Flow Meter (Product Code: SLE/BL/047) is a portable meter used to measure peak expiratory flow — how fast a person can blow air out of the lungs in one sharp breath — in school, college and health-science teaching laboratories. Each unit is individually calibrated, reads on a 60–800 scale and has an integral one-way valve to reduce the risk of cross-infection when a class shares it. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Peak Flow Meter Used For?
For a class reading, the student stands up straight, returns the pointer to the bottom of the scale, takes the fullest breath possible, seals the lips around the mouthpiece and blows out as hard and fast as they can. Repeating this three times and recording the highest value gives a fair result. Students can then compare readings across the group, look for a link with height, or measure again after a short burst of activity.
Teachers often use the readings to open a discussion on why airways narrow in conditions such as asthma and how people monitor their own breathing, which makes the meter a practical addition to biology lab equipment for respiratory-system topics. Remind the class that school readings are for learning only and are not a medical check. Use a fresh mouthpiece for every student and store the meter safely between lessons so the scale and pointer stay undamaged.
What to Specify When Ordering
- Number of meters, for example one per practical group
- Packs of disposable mouthpieces, which are sold separately
- Whether you need the product datasheet with the scale units for worksheets
- Any calibration paperwork your institution requires, raised before quotation

Frequently Asked Questions
Are mouthpieces included with the Peak Flow Meter?
Mouthpieces are not listed as part of the Peak Flow Meter. Disposable mouthpieces made for it are available separately as Plastic Disposable Mouthpieces for Peak Flow Meter, so each student can blow through a clean one during class readings.
What range does the Peak Flow Meter scale cover?
The Peak Flow Meter scale runs from 60 to 800. Our current listing does not state the scale units, so ask us for the product datasheet if you need them for a worksheet or practical record book.
What does the one-way valve on the Peak Flow Meter do?
The integral one-way valve on the Peak Flow Meter lets air flow out through the meter while stopping the user from drawing air back through it, which reduces the risk of cross-infection when a group shares one meter.
Can the Peak Flow Meter be used to diagnose a breathing problem?
No. In a school or college, the Peak Flow Meter is a teaching instrument for demonstrating lung function, and class readings are for learning only. Anyone with a breathing concern should see a doctor rather than rely on a classroom reading.
Is each Peak Flow Meter calibrated?
Yes. Every Peak Flow Meter is individually calibrated for high inter- and intra-device accuracy. If your institution needs a formal calibration certificate, raise it with us before ordering so ScienceLab can advise what documentation is possible.
Who supplies the Peak Flow Meter?
The Peak Flow Meter is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges, health-science departments and distributors in India and international markets, together with its separately sold disposable mouthpieces.
Can ScienceLab supply Peak Flow Meters for a whole class?
Yes. For a class set of Peak Flow Meters, send the number of meters, the mouthpiece packs you need and the delivery location, and ScienceLab will quote for supply within India or for export.
