The infrared thermometer provides a fast and easy way of measuring the temperature without touching the object, widely applicable in oil and chemical industry, railway, electricity, textile processing, etc. Features: Safely measure surface temperature of hot, hazardous or hard-to-reach objects without contact. Only takes 0.5s to deliver temperatures on colored LCD screen, accurate and efficient. Emissivity adjustable from 0.10 to 1.00 for various types of objects. Broad temperature range of -50℃～850℃(-58℉～1562℉), which is ideal for professional applications. Automatically record data after each measurement, data storage capacity is 100. Equipped with a UV light, which can be used for fluorescent leakage detection. Comes with Type K thermocouple for contact measurements. More features: auto shut off after 30s without operation; high and low temperature alarm prompt; Celsius(℃) and Fahrenheit(℉) switchable; laser positioning; locating a hot spot.
