Microtek IT 1520 Non-Contact Infra Red Thermometer is an advanced technology product which can measure the temperature of a human body by receiving the infrared energy emitted from the human body. It can also measure the temperature of a room and any object. It is ultra-fast, accurate and switchable with a fever alarm. The primary function of the Microtek portable infrared thermometer, with many features available, is very similar in almost all models. The first step is to take a measure, determining the target you want. All thermometers controlled by infrared lasers, no matter how designed, will have ways to "identify" the tool on the target. Some versions are made in such a way that targeting is a target. Some have a guide, such as a laser location or a group of laser markers that indicate the target area. The temperature measurement is taken when the "trigger" is activated. It is usually a button under the pyrometer (gun style) or higher (television remote control style). The accuracy of the measure depends on certain factors. Everything liquid, solid, or gas constantly exchanges hot energy in the form of electric radiation and the environment. If there is a temperature difference between the object in question and the environment, there will be a complete heat transfer in the form of heat. This means that the cold object will be heated carelessly around the environment, and then the warm object will be cooled. If the object in question is at the same ambient temperature, the net radiation energy exchange will be zero. In any case, the magnitude of the radiation signals depends on the object and the total ambient temperature relative to zero completely (0 K, -273.16 C, -459.69 F). Microtek Infrared thermometers take advantage of this "radiation dependence" at temperatures to produce the target object and show the results for the operator to read. | Uses: This infrared thermometer accurately measures the body or core temperature of the body or an object without coming in contact with it. | Product Specifications and Features: Non-contact measuring distance: Between 1 to 15 cm Batteries: 2 AA Light weight: 105 gms Measurement time: Accuracy: Up to +0.36 Fever alarm: >100.2 (automatic alarm with red backlight Four components: Scan button, LCD display, battery cover and function buttons Calibration- Quick and easy calibration feature for accurate temperature reading Easy to use- One-key measurement, auto shutdown, ergonomic and energy-saving design Non-contact- Measure the temperature from the forehead of the human body without touching the skin Screen display- Large screen with backlight, which helps to see readings in all lighting conditions Colour range of temperature- Green: T 100.2F 3-in-1 measurement- Body, object and room temperature Temperature alarm and memory- In case of high temperature, gives audio and visual indications, and you can store up to 32 readings | Good to Know: C and F switchable- Easily switch between Fahrenheit and celsius Made in India | Type of Thermometer: Infrared thermometer. | Directions For Use: Start by inserting the batteries Press the trigger (T) button after showing the thermometer to your body and view F readings Press the mode (M) button to view results in C | Safety Information: Read the label carefully before use Store in a cool and dry place, away from sunlight Keep out of reach of children Do not leave your child alone while having their temperature taken
