The Wireless HVAC Guide® System Analyzer will reduce call-backs by giving you a wide variety of tests to diagnose HVACR systems and lower your customer's energy bills. It walks you step-by-step through each test procedure to make your job easier, faster and better.

When coupled with the new ET2W Wireless Transmitter (included with every HG3), the HG3 system turns every Fieldpiece Accessory Head into a wireless device, capable of sending measurements from up to 100 feet away. So you can take up to 13 measurements (12 wirelessly and one directly on the HG3) all at once to give you an live snapshot of the entire system.

Attach any Fieldpiece Accessory Head to the ET2W to view or log measurements on the HG3 in real-time. The HG3 has the capability to wirelessly and simultaneously read up to 12 wireless signals. A 13th accessory head can be attached directly to the HG3 to give you the ability to record 13 parameters at one time.

Test procedures are included for Superheat, Subcooling, Combustion Analysis, Target Evap Exit Temperature (temperature drop across the evaporator coil), CFM (air balancing), CheckMe!® Evaluation. and Service light set up are built into the HVAC Guide to streamline each test.

The HVAC Guide® System Analyzer also has a data logging switch position to record up to 13 measurements at one time. With the Display switch position view one parameter by connecting any Fieldpiece Accessory Heads directly or wirelessly. Do it right the first time, do it faster, easier, more completely, and avoid call-backs in the process

Features and Benefits
The HG3 holds up to 200 tests on its internal memory, so you can easily show your customers what's going on with their system, and what the recommended fixes are. You can even have them review the screen with you in real-time while you're receiving measurement data wirelessly.

In addition, all tests can be downloaded to a personal computer so you can not only print out your tests results for your customers, but you can also store all the data to reference the next time you are called to the job site.

You can also easily and accurately perform CFM tests because the HG3 does your calculations for you, automatically. The HG3 will calculate the average, max, and min air velocity for up to 13 grilles, then calculate the Total Return and Total Supply for the entire system.
