Abstract

The invention relates to an infrared (“IR”) thermometer that includes a pistol-grip handle which is operable to receive a high-voltage removable and rechargeable battery pack. In one embodiment, the thermometer includes a main body, a handle portion, a trigger, a display, a control section, an LED flashlight, a plurality of sensors, and a high-voltage removable and rechargeable battery pack. The handle forms an oblique angle with respect to the main body and includes a first recess for receiving the battery pack. The trigger is operable to initiate a temperature measurement, and the display is operable to display, among other things, a measured temperature. The plurality of sensors include, for example, an IR temperature sensor, a thermocouple, a humidity sensor, and an ambient temperature sensor.

Claims

1. An infrared thermometer configured to receive a removable and rechargeable battery pack, the thermometer comprising:

a main body having a first axis;

a handle having a second axis and including a first recess configured to receive the battery pack, the first recess including at least first and second electrical terminals which are exposed when the battery pack is not inserted into the first recess,

wherein the second axis forms an oblique angle with the first axis, and

wherein the battery pack is inserted into the first recess along the second axis;

an infrared temperature sensor operable to sense a first temperature of a first area in a non-contact manner;

a contact temperature sensor operable to sense a second temperature of a second area in a contact manner; and

a display configured to display an indication of the first temperature and the second temperature.

2. The thermometer of claim 1, wherein the contact temperature sensor and the infrared temperature sensor are independent of one another.

3. The thermometer of claim 1, further comprising an LED flashlight.

4. The thermometer of claim 1, wherein the battery pack is a lithium-ion battery pack.

5. The thermometer of claim 1, further comprising a humidity sensor and an ambient temperature sensor.

6. The thermometer of claim 1, further comprising a trigger operable to initiate an infrared temperature measurement.

7. The thermometer of claim 6, further comprising an electronic trigger lock.

8. The thermometer of claim 1, wherein the first area is located on a first object and the second area is located on a second object.

9. A method of operating an infrared thermometer that includes a handle portion, an infrared temperature sensor, a contact temperature sensor, and a humidity sensor, the method comprising:

powering the infrared thermometer with a removable battery pack inserted into a recess of the handle portion;

sensing, using the infrared temperature sensor, a first temperature of a first area;

sensing, using the contact temperature sensor, a second temperature of a second area;

sensing, using the humidity sensor, a first humidity;

compensating, using an ambient temperature sensor, the first temperature, the second temperature, and the first humidity to generate a compensated first temperature, a compensated second temperature, and a compensated first humidity; and

displaying, on a display, an indication of the compensated first temperature and the compensated second temperature.

10. The method of claim 9, wherein the contact temperature sensor and the infrared temperature sensor are independent of one another.

11. The method of claim 9, further comprising illuminating at least one of the first area and the second area using an LED flashlight.

12. The method of claim 9, wherein the battery pack is a lithium-ion battery pack.

13. The method of claim 9, wherein the first temperature is sensed when a trigger is engaged.

14. The method of claim 13, further comprising locking the trigger electronically.

15. An infrared thermometer configured to receive a removable and rechargeable battery pack, the thermometer comprising:

a main body having a first axis;

a handle having a second axis and including first recess configured to receive the battery pack, the first recess including at least first and second electrical terminals which are exposed when the battery pack is not inserted into the first recess,

wherein the second axis forms an oblique angle with the first axis, and

wherein the battery pack is inserted into the first recess along the second axis;

an infrared temperature sensor operable to sense a first temperature of a first area in a non-contact manner;

a contact temperature sensor operable to sense a second temperature of a second area in a contact manner;

a trigger operable to initiate an infrared temperature measurement;

a flashlight which receives power from the battery pack; and

a display configured to display an indication of the first temperature and the second temperature.

16. The thermometer of claim 15, wherein the contact temperature sensor and the infrared temperature sensor are independent of one another.

17. The thermometer of claim 15, wherein the battery pack is a lithium-ion battery pack.

18. The thermometer of claim 15, further comprising an electronic trigger lock.

19. The thermometer of claim 15, wherein the flashlight is an LED flashlight.

20. The thermometer of claim 15, wherein the first area is located on a first object and the second area is located on a second object.
