Southwire’s 31011F infrared thermometer has a 10:1 distance-to-spot ratio, which means that when users aim the thermometer at a surface that is 10 in. away, the thermometer gathers temperature information from a measurement area of 1 in. in diameter. It operates in temperatures between –4ºF and 752ºF. 

Amprobe’s IR-730 infrared thermometer is designed to check AC units, ventilation, bearings, motors and transformers for overheating, bad fuses and electrical connections. It measures temperatures from –26°F to 2,282°F. It features a laser pointer, backlit, dual LCD display and a 30:1 distance-to-spot ratio.

Klein Tools’ infrared thermometer measures between –4°F and 752°F. Users can select between Fahrenheit and Celsius measurements. It features drop protection up to 2 m and has an easy-to-read backlight. The optical resolution is 10:1. Auto power-off conserves battery life, and it also features a targeting laser and an automatic hold.

Fluke’s high-temperature infrared thermometer features a dual laser sighting for targeting. It operates at temperatures between –22°F and 1,652°F. It features a three-button on screen menu and multilingual interface. Users can adjust emissivity, start data logging or turn alarms on and off.

Klein Tools’ dual-laser infrared thermometer measures temperatures from -40 to 1,200°F. It measures bulk temperatures of air, gas or liquids when using a standard K-Type probe. It has a backlit display, an over-mold housing, IP-54-rated ingress protection for water- and dust-resistance, and a 3 m drop protection. It includes a custom carrying pouch, K-type temperature probe and battery.

Southwire Tools’ 1,500°F infrared thermometer features 20:1 distance-to-spot ratio, high and low temperature alarms (set by the user), a lock-on feature for continuous measurements and dual lasers to pinpoint the target.

Klein Tools’ IR5 dual-laser, IR thermometer uses a 12-to-1 distance-to-spot ratio to measure temperatures between –22°F and 752°F. It has an overmolded housing, can withstand drops of more than 6 ft. onto concrete or steel and has several calculation modes.
