I live by mine and it has never let me down.

PerformAIRE weather stations are the only patented system that has a Density Altitude calculation specific for determining horse power in an internal combustion engine. It is critical to measure the amount of oxygen and the amount of water in a sample of air in order to determine correctly how it will effect the change in horsepower.

Systems that are designed for hiking, aviation, sailing, etc that are not licensed by Altronics can only calculate "text book" Density that will not always correctly relate to horsepower changes. Although it may seem ok under minimal or similar changes in atmosphere it will prove inaccurate as conditions change.

Would you recommend the KESTREL 4250?

Not for drag racing.

How do you measure Oxygen do you have a sensor? I have used a Oxygen Meter since 1985. % of oxygen has a big affect on performance! a change from 19.8% to 19.5 is big!

Worse, Like asking a Ford if he should by a Hyundai!!!!!


Yes, Oxygen is the name of the game. Fuel + O2 makes horsepower. The Oxygen sensor is an option on almost all of our weather stations. Without it we assume a constant percentage of O2 in the atmosphere and by measuring the density we know the assumed O2 content. With an O2 sensor and by measuring the density we do not have to ASSUME, but can calculate the ACTUAL amount of Oxygen.

With that said, if you race at the same location all the time the O2 level tends to be stable because the environment does not change, (vegetation, pollution, etc..). So the oxygen sensor tends to benefit the racer that travels to many different tracks that are located in different environments.
