<p>Not for Humans: Industrial infrared thermometers are designed to measure the temperature of objects and liquid surfaces, and cannot measure the detection of human body temperature. Non-contact measurement, suitable for industrial, cooking food surface temperature detection. Wavelength 630nm~670nm, output power &lt;1mW.Laser Positioning &amp; High and Low Temperature Alarm: One-click to turn on the laser light to locate and measure objects, and quickly read and measure surface temperature. When the measured temperature exceeds or falls below the set alarm value, the instrument will issue a beep alarm (alarm point can be adjusted).High-precision Measurement: The industrial thermometer measures from -58F to 1832F (-50C to 1000C), with an error of 1F (0.5C). To provide accurate and reliable temperature measurements, infrared thermometers incorporate advanced sensing technology and sophisticated measurement algorithms. For bakery, liquid or hard-to-reach objects, use this product for safe non-contact measurement.HD VA Color LCD Display: High-definition color VA display and backlit display, suitable for working in low or no light conditions. MAX/MIN/DIF/AVG/HOLD measurement mode display, one key to switch between 5 modes, and the temperature measurement gun automatically calculates the results. Power display, sound indication. 3 emissivity displays (high/medium/low). Comes with 2*AAA batteries.Powerful Industrial Thermometer: The high-end industrial thermometer has a fast response time of 0.25 seconds, automatic shutdown without operation in 18 seconds, adjustable emissivity (0.95/0.85/0.75), adjustable high and low temperature alarm points and built-in beeper Sounder alarm function.</p>
