This two-in-one thermometer by Escali allows you to measure both surface and internal temperatures with one device. Quickly switching between infrared mode and probe mode, you can accurately measure the surface temperature of a grill grate, then move to probe mode to measure the internal temperature of meat. The infrared mode has a 5:1 distance to target ratio for safely measuring extremely hot surfaces. A Scan and Hold function helps you scan an area to identify hot or cold spots, then easily release. The folding probe design is easy to store. The large backlit display offers a clear view and there is also an auto off feature to save battery life. Temperature Range: -22°F to 716°F Infrared -22°F – 572°F Probe Probe Length: 4.5” Battery: 2 x CR2032 (included)
