Fast & Precision Non-Contact Temperature Measurement
Are you an industrial technician inspecting overheating engines? Or perhaps a home chef perfecting a backyard pizza oven? Either way, having a reliable ut300s infrared thermometer is absolutely essential. In fact, this CE-certified pyrometer provides a completely safe way to measure extreme surface temperatures remotely.

Adjustable Emissivity & Safety
Different physical materials reflect infrared energy differently constantly. Fortunately, you can adjust the unit’s emissivity from 0.10 to 1.00 easily. Consequently, this laser pyrometer accurately reads shiny metals or dark matte plastics. What does a 12:1 distance-to-spot ratio actually mean? Basically, you can accurately measure a 1-inch target area from exactly 12 inches away. Thanks to this, the laser ensures your physical safety around high-voltage panels.


Extreme Range & Smart Alarms
First, it boasts a wide testing spectrum from -32℃ to 400℃ (-25.6℉ to 752℉). Furthermore, the device pulls accurate thermal readings incredibly fast with a ≤ 0.5-second response time. Therefore, you detect thermal anomalies instantly. You can easily set custom high and low-temperature alarms. Moreover, it features highly useful MAX/MIN/AVG data hold functions. Also, it includes a bright high-contrast color LCD backlight for dark mechanical rooms.

The diagnostic versatility of the ut300s infrared thermometer is truly unmatched. For instance, commercial chefs rely on it to verify pizza oven stones. Meanwhile, industrial technicians use it to identify bad electrical contacts safely. Add this powerful temp gun to your toolkit today. Explore our Digital Temperature Meters for more diagnostics.

UT300S User Manual (PDF)FAQs
Q1: What does adjustable emissivity mean, and why do I need it?
A: Basically, emissivity measures how efficiently a surface emits thermal energy. Most basic thermometers have a fixed setting of 0.95. Unfortunately, this causes incorrect readings on shiny surfaces like stainless steel. However, the UT300S infrared thermometer allows adjustments from 0.10 to 1.00. Therefore, you get pinpoint accuracy on matte plastics, BBQ grills, or shiny engine parts.
Q2: What is a 12:1 Distance to Spot (D:S) ratio?
A: Essentially, a 12:1 D:S ratio is quite simple to understand. At a distance of 12 inches away, the thermometer measures a 1-inch target spot. Consequently, you can accurately measure specific, small components inside machinery. Most importantly, you avoid getting dangerously close to extreme heat or moving parts.
Q3: Can I use this laser temp gun to measure human body temperature?
A: No, you cannot. Indeed, this is an industrial-grade laser pyrometer. It is specifically calibrated for high temperatures ranging from -32℃ to 400℃. Therefore, it is strictly designed for cooking, HVAC testing, and machinery diagnostics. Consequently, it is not accurate enough for medical human body temperature monitoring.
Q4: How long does the battery last, and does it turn off automatically?
A: First, the device runs on a standard 9V battery (6F22). Furthermore, it features a smart auto power-off function to extend battery life. Specifically, it shuts down completely after 8 seconds of inactivity. Additionally, it has a low battery indicator on the screen. Thus, you always know exactly when a replacement is needed.
