| The SPK3 temperature pocket tool has convenient two-way temperatures with both a folding in-duct Rod temperature and an infrared 8:1 gun |
| The IR takes quick surface temperature readings, and the rod measures in the duct easily with a hanging hook for hands-free testing |
| The SPK3 temperature tool also features max/min/hold functions, a backlight, and a display that flips depending on what temperature mode is chosen |
| Plus, the SPK3 quickly calculates T1-T2 and it works across both the IR and rod modes |
| Great to quickly assess a system |
| 8:1 IR for register and ambient temps |
| Hands free in-duct measurements |
