When you're diagnosing
auto A/C,
it's really important to know the Relative
Humidity! |
How do you determine
the relative humidity? You use a 'psychrometer'! |

A
Psychrometer is a rather simple instrument to
make and use if you have
all the right information! This A/CE™ manual gives you
everything you need to know! It includes
detailed step by step instructions and
full color photos! Just because we've made it
simple and easy to make and understand, don't confuse it with being a
toy! The details included in this eBook manual show you how to make an
accurate and reliable psychrometer that will
provide years of service for just a few dollars!
Did
you know that there was a time when vehicle manufacturer's shop manuals listed
a psychrometer as a 'required' A/C service technician
tool? That's because knowing what the relative humidity is and
understanding how it effects the cooling of your auto A/C system is
important to proper diagnosis! |
|
|
|
When
you get this information, it will include a Humidity Based
Pressure/Temperature
WIZ Chart™! That's your complete reference
when diagnosing any auto A/C system! The chart gives you all the
detailed refrigerant pressure gauge readings
(both high and low side readings) that you should be getting, plus
the expected duct outlet temperature, all depending
on both the ambient temperature and the relative
humidity! (The chart details all of this for both R-12 and R-134a
systems!)
Why
is the Humidity based Pressure/Temperature chart important? Well, did you
know that depending on the ambient air temperature and the humidity of the
day, a properly operating A/C system may only
produce 50 °F air at the duct outlets?
If that's the case, you could be chasing expensive parts wasting time and
money recharging the A/C system for no reason!
Also
included is the WIZ Chart™ Psychrometer Graph! Why is that
important? That's the graph you use to quickly 'chart' and determine
the relative humidity. Don't worry, we not only provide you the
detailed step-by-step instructions on how to
make a psychrometer, we show you
exactly how to use it and chart your readings!
Within minutes you will be able to accurately
calculate the relative humidity right in your own
shop!
So
now ask yourself one more time. If the A/C system you're working on is only
producing 50 °F air at the duct outlets,
is it working properly? You won't know until
you can determine the relative humidity right on your
shop floor and then check the Humidity Based Pressure/Temperature
WIZ Chart™. Quit guessing! Make all of
your auto A/C diagnosis accurate by using your
own psychrometer to determine the relative humidity and compare your pressure
gauge readings to the Humidity Based Pressure/Temperature WIZ Chart™!

Now here's a peek
at what's included! |
Step-by-step details
showing you exactly how to
make your psychrometer! |
 |
Not
only do we include a complete list of everything you
need (keep in mind that everything you need will only cost a few dollars!)
but we show you what to watch for; how to
assemble it; and then we even detail
how to use it for maximum
accuracy and reliability! |
|
|
|
How do you really
determine the relative humidity? |
 |
We
show you exactly how to do this. You'll quickly
be able to use the WIZ Chart™ Psychrometer Graph to chart your readings
and accurately determine the
relative humidity in just a
few minutes! That's right! Know exactly what the humidity is right
inside your own shop... all in a couple of
minutes... all for just a few dollars!

More examples
so that you're really comfortable! |
 |
To
be sure that you're comfortable with using your psychrometer, we've included
extra real examples of readings we took. In
fact, we completed these readings in just a few
minutes. What was surprising was that we found there was a
difference in humidity inside when compared
to the readings outside! Did you know that there could be changes? That means
the relative humidity that you hear in weather reports
don't really matter to your A/C diagnosis!
The humidity in your shop could be
different! |

|
A look at the
two WIZ Charts™ included with this A/CE™ Manual !
|
 |
Using
the included Humidity Based Pressure/Temperature WIZ Chart™ assures
you accurate A/C diagnosis! That's because it
includes expected (maximum allowable) high and low side pressure gauge
readings for both R-12 and R-134a systems! All
of the readings are based on the ambient (outside) air temperature
and the relative humidity! |
|
|
|
Accurately determine
the relative humidity right in your shop...
all within a couple of minutes! |
 |
We've
also included this Psychrometer Graph WIZ Chart™ that lets you
accurately determine the relative humidity
in a couple of minutes! It's
easy to use and we provide you
detailed step-by-step instructions on just how
to use it! Get accurate A/C diagnosis when you really
know what the relative humidity is! |
