Measures body temps of 89.6 to 108.5 F (32.0 to 42.5 C) with a resolution of 0.18 F (0.1 C) and color changing backlit display to warn you when hot is too hot. Normal operating temperature (ambient air) range is 60.8 to 95 F (16.0 to 35.0 C), and the device should be held between 0.4" and 2" inches from those foreheads. Want to fry an egg on your car dash?

Microscope glassware for examination of blood, pond water, mold, and other minutiae. All of the microscope slides are optically clear glass 26mm x 76mm (about 1" x 3"), between 1mm and 1.2mm thick.
