Review on BTMETER BT-1500 Non-Contact Pyrometer: Industrial Laser Thermometer Gun for High Temperature Measurements by David Reyes

Bad: The listing states +/- 2% accuracy in the textual description at the top of the listing. However, there is an additional box further down the list with more details, clearly marked with an asterisk. This appears to be legitimate fine print as there is no apparent dilution of the original list of fine print. The listings in the fine print give +/- 7.2 F < 32 F and +/- (2% + 3.6 F) for temperatures > 32 F. This means that at room temperature (70F) +/- 5F errors will be displayed. My experience is slightly worse (+/-8F) compared to a +/-0.7F thermal pen that was well accustomed to the surface in question (kitchen counter). It's also not very repetitive. Shoot the tabletop and get 60F (when Thermapen says 68F). Take it outside and shoot both hot and cold (clouds, hot grill), carry it back and shoot the counter again and get 74F. The meter did not change the temperature. What's good: It can shoot burning charcoal in a ceramic grill without exceeding the maximum limit. Hopefully this allows me to focus on pizza without a burnt crust using just the stone on the spider web (instead of the stone and heat reflector). It also has a nice solid feel and dual aiming lasers. Instead of not-so-useful features (very dim white flashlight LEDs), the manufacturer should improve accuracy and repeatability. There are other inexpensive (smaller range) infrared thermometers that are much more accurate and repeatable. I have another such device that matches the thermal pen to the degree (simultaneously in the other hand) for the same exercise described above.
