Abstract

In a device and method for taking temperature readings on an HVAC system, a first probe is connectable in thermal communication with the HVAC system for taking a first temperature reading thereof. A second probe is connectable in thermal communication with the HVAC system for taking a second temperature reading thereof that is independent of the first temperature reading. A digital display is connectable to the first and second probes for displaying the first and second temperature readings.

Claims

4. The apparatus of claim 1, wherein each of the first probe and the second probe comprises an electrical lead comprising a first end configured to be removably coupled to the corresponding first female plug and the second female plug and a distal second end comprising a temperature sensor for taking the temperature readings.

5. The apparatus of claim 1, wherein the display generates color-coded temperatures, and each color corresponds to a respective refrigerant type.

6. The apparatus of claim 1, wherein the temperature reading device calculates super-heated and sub-cooling refrigerant temperatures.

7. The apparatus of claim 1, wherein the temperature reading device is configured to be at least one of:

(i) solar powered with battery backup, and (ii) fully battery powered for low light environments.

8. The apparatus of claim 1, wherein the temperature reading device further comprises a solar array for solar powering the display and/or the first probe and the second probes.

9. The apparatus of claim 1, further comprising a manifold attachable to the HVAC system and comprising at least one analog gauge, wherein the temperature reading device is mounted on the manifold.

10. The apparatus of claim 9, wherein the display is (i) fixedly secured in a central region of the manifold and simultaneously displays the first temperature reading and the second temperature reading or (ii) is removably attachable to a central region of the manifold and simultaneously displays the first temperature reading and the second temperature reading.

11. The apparatus of claim 9, wherein the manifold comprises a first gauge and a second gauge, wherein the display is mounted between the first gauge and the second gauge.
