Sper 800111 IR Thermometer Infrared Gun 20:1 with Dew Point Alert

Shows areas where mold and mildew will grow

• Surface temperature  • Surface dewpoint  • Ambient temperature  • Ambient RH

Residential and commercial users can quickly find areas where mildew will grow with a simple scan. Point the gauge at questionable areas and read surface temperature on the large multi-line backlit LCD display. Be careful to point the dual lasers exactly where you want to measure and not at the wrong spot. The meter measures ambient air temperature, relative humidity and dew point. It then compares the surface temperature to the air conditions to predict condensation on that surface. The green LED will turn yellow then red as the temperature approaches dew point indicating areas where mold and mildew will grow. An audible alarm also sounds as moisture levels increase during the scan. The 20:1 IR thermometer has dual-point lasers and a hold function. For best results, calibrate the thermometer periodically by following calibration procedures such as testing against a known reference like an ice bath to verify and adjust accuracy. Testing calibration helps ensure the device gives an accurate reading. Comes with carrying case, 9V battery and instruction manual.

Dim: 6 ½” x 3 ¼” x 2 ¼” (168 x 82 x 58 mm). Weight: 5.7oz (163g)

This infrared thermometer will work on skin but not recommended for forehead temperature since the beam should not be pointed at the eyes.

Introduction

Infrared thermometers are innovative tools to measure surface temperatures quickly and safely from a distance. Unlike traditional, these devices use infrared radiation to detect the heat emitted by an object, so you can get an accurate temperature reading without physical contact. This non-contact method is especially useful when safety, hygiene or convenience is a concern. Laser thermometers, a type of infrared thermometer, use a visible laser to help you aim exactly at the target area. With their high accuracy, precision and ability to measure temperatures in hard to reach or hazardous locations, infrared thermometers have become essential in industrial, culinary and scientific applications. Their advanced features and reliability make them a top choice for professionals and home users.

Features

When choosing an infrared thermometer, consider the following key features that affect performance and usability. High distance-to-spot ratio allows for precise temperature measurement from farther away, easy to measure hard to reach surfaces. Adjustable emissivity is crucial for accurate reading on different materials, surfaces like metal, glass or painted finish emit infrared radiation differently. Wide temperature range ensures the thermometer can handle from freezing to extremely hot environments. Fast response time is important for real-time monitoring especially in dynamic environment. Dual laser targeting helps you pinpoint the exact measurement area, reduces errors. Backlit display for low light and rugged design for industrial use makes the device more practical and reliable.

Specifications

Infrared thermometers are defined by several specifications that determine their performance in different applications. Temperature range, usually from -50°C to 1000°C, indicates the extremes the device can measure. Accuracy, ±1% or ±2°C, is important for trustworthy results. Response time, 0.1 seconds, is for real-time monitoring. Distance-to-spot ratio, 20:1, is how large an area the measures relative from the target—higher ratio means more precise targeting from farther away. Emissivity settings, adjustable to match the surface being measured, is important for accurate reading on different materials. Type of sensor, thermopile or pyroelectric, affects the device’s sensitivity and performance. All these specifications help you choose the right infrared thermometer for your needs.

How it Works

An infrared thermometer works by detecting the radiation emitted by all objects. When you point the thermometer at a surface, a built-in laser pointer helps you aim at the exact spot you want to measure. The sensor, usually a thermopile or pyroelectric detector, captures the radiation and converts it into an electrical signal. This signal is then processed and displayed as a temperature reading on the screen. The gauge takes into account factors—the efficiency of a surface to emit infrared radiation—and ambient temperature to ensure the reading is as accurate as possible. This technology allows for quick non-contact temperature measurement, perfect for situations where safety, hygiene or convenience is a concern.

Comparison to Others

Infrared thermometers are different from contact thermometers and probe thermometers as they provide non-contact temperature reading. This is useful when measuring hot, moving or hard to reach surfaces or when hygiene is a concern. Infrared thermometers give fast and accurate temperature reading without touching the object, reduces the risk of contamination or injury. However, they are best for surface temperature measurement and not ideal for internal temperature measurement like inside cooked food. When internal temperature is critical, probe thermometers or thermocouples are more suitable. Most infrared thermometers can measure temperature on various surfaces but their accuracy can be affected by surface reflectivity which should be considered when choosing the right device for your needs.

Uses

Infrared thermometers are used in many applications across different industries. In the kitchen, they are indispensable for measuring surface temperature of cooking surfaces like cast iron skillets, griddles and pizza ovens to ensure food is cooked at the right temperature. In industrial settings, they monitor equipment and machinery, detect overheating or identify maintenance needs before problems arise. Scientific researchers use infrared thermometers for precise temperature measurement in materials science, biology and chemistry experiments. Other uses include HVAC system diagnostics, automotive troubleshooting and medical applications where non-contact temperature measurement is essential for safety and efficiency. The versatility and accuracy of infrared thermometers make them a trusted tool for professionals and hobbyists.
