A CLOSER LOOK
A gray surface thermometer rated to a 420°C target
The gray LEC-420 is an option for non-contact surface readings within its stated −50 to 420°C range, also expressed as −58 to 788°F. Choose it when that target range covers the surfaces you need to measure; TempPro’s TP30 is an alternative with a higher stated upper target of 1022°F.
Adjustable emissivity from 0.1 to 1.0, a 12:1 distance-to-spot ratio, backlight and read hold give you controls for the surface and the display. Celsius/Fahrenheit switching is included. The seller claims ±1.5 percent accuracy and suggests 0.95 for general household use; follow the material-specific instructions rather than treating that setting as correct for every oven floor.
A carrying pouch and English manual are named in the package. Battery details need confirmation: the descriptive contents say two batteries, while another entry names a CR2032 pack. Wipe-clean care is stated. The thermometer is intended for inanimate surfaces, not internal food or body readings; keep the laser away from eyes and skin, and do not expose the instrument itself to oven heat.

Fit & buying checks for this reference
Confirm the power configuration
Check exact battery type and quantity for this selected gray model before buying replacements.
Compare your target with the upper limit
Do not choose this range on the assumption that every pizza-oven surface remains below 420°C.
Care instructions
Source care and laser limitation
Wipe clean is stated. The source says inanimate objects only and cautions against directing the laser at eyes or skin; Oven Safe is not an established exposure procedure.
Questions about this selected product
Does it include a carrying pouch?
Yes. A carrying pouch and English manual are explicitly named.
Which batteries should I buy for it?
Confirm the configuration before buying replacements: the description says two batteries, while another entry names a CR2032 pack.
Is 0.95 the right emissivity setting for my oven floor?
It is a broad household recommendation. Use the instructions for the actual surface rather than assuming one setting suits every material.
