The TruZone Peak Flow Meter's ("PFM") unique logarithmic scale simplifies the reading and recording of the Peak Expiratory Flow ("PEF"). ColorZone Tapes help to easily identify target zones by effectively customizing the device to measure against the patient's best PEF. This feature makes asthma management easy. * The transparent ColorZone Tapes are simple to apply and use. One tape applied to the TruZone PFM logarithmic scale automatically calculates the zones for proper PEF trending. The three "color zones", (with dual yellow), help guide the patient on what action to take to control their asthma.

Truzone Peak Flow Meter
Very satisfied with the product. Works as supposed to. Compact and easy to use. Although when it arrived via USPS, the box inside the package was smashed and I thought the meter would be broken. It was fine. I would suggest better crush proof packaging for mailing to the customer. Otherwise, completely satisfied.

peak flow meter
although I can get a free one from my doctor's office this one is a lot nicer. It works every time once you get the hang of using it correctly.I would recommend this product.

Impossible for me to shake down to zero
I think this product is probably accurate; however, I cannot shake it down to the beginning of 0. My husband has to shake it down for me each time I use it. If you consider that you may not have the strength to shake it down fast and hard, don't consider buying this.
