Kizen Infrared Temperature Gun - Handheld Surface Infrared Thermometer for Griddle, Grill, Pizza Oven, -58F to 1112F Review (2026)

What this thermometer measures

This is the Kizen LaserPro LP300, a handheld, non-contact infrared thermometer with a stated range of -58F to 1112F according to Kizen's own listings, wide enough to cover both a cold freezer check and a screaming hot pizza stone or steel. Retailer descriptions note it takes a reading in about 500 milliseconds, which matters when checking a stone through an open oven door where every second lets heat escape. Like all infrared guns, it reads surface temperature only, not the internal temperature of dough or the air temperature inside a closed oven, so it is best used to confirm the floor of a pizza oven has reached target heat right before launching a pie rather than to judge doneness of the finished pizza itself.

Build and everyday handling

Kizen's listings describe a built-in laser pointer with a 12:1 distance-to-spot ratio, meaning the measured spot gets larger the farther the gun is held from the surface, and the brand recommends around 14 inches for accurate readings, which is a comfortable working distance from a hot oven mouth. A backlit LCD display is listed as a feature, useful for reading numbers in low evening light during an outdoor pizza session. The gun runs on two AAA batteries per the listed specs, which are easy to find and replace compared with some rival guns that use less common battery sizes, though the listing does not state battery life, so keeping a spare set on hand for a long cooking session is a reasonable precaution.

Accuracy and emissivity

Retailer listings for this model mention adjustable emissivity, a setting that compensates for how different surfaces radiate heat, which matters because a polished steel or stone reads differently than a matte cast iron surface at the same actual temperature. Getting an accurate reading on a pizza steel or stone means setting emissivity appropriately for that material rather than trusting the default setting blindly, and the listing does not spell out the specific emissivity range or default value, so checking the included manual before the first use is worth the few minutes it takes. As with any infrared gun in this price range, expect readings to be a useful guide for hitting a target range rather than a certified, lab-accurate number.

How it compares to other pizza thermometers

Against other infrared guns marketed for pizza ovens, this one sits in the same general range as rival Etekcity models, with a similar maximum temperature ceiling and a comparable price point, rather than standing out with a meaningfully wider range or extra features like a probe thermometer. Kizen is a recognized budget brand in the infrared thermometer space, more focused on affordability than the premium features found on oven-branded accessories like the more expensive infrared guns sold directly by pizza oven makers. For someone who already owns a wood-fired or gas pizza oven and just wants a reliable way to confirm the stone has reached temperature, this sits in a sensible middle ground between a bargain unbranded gun and a name-brand oven accessory.

Who should buy this

This thermometer makes the most sense for home pizza cooks who want a quick, repeatable way to check stone or steel surface temperature before each bake without spending on a premium oven-branded accessory. Anyone who wants precise, calibrated readings for professional or scientific use should look elsewhere, since this is a consumer-grade tool built for kitchen and backyard use rather than lab work. The wide temperature range covers the needs of most home pizza ovens, wood-fired or gas, along with grills and griddles, so it can pull double duty beyond pizza nights if a household also grills or smokes regularly.
