Wir vergleichen verschiedene Faktoren und verleihen jedem Artikel dann die abschließende Testnote. It is perfect for industrial use, HVAC, chemicals, mechanical equipment, refrigerators etc. Die preiswerten IR-Pyrometer sind ideal für den Einsatz in … Yes, the thermometer automatically turns off when it’s inactive for 15 seconds. It is important to note, however, that the readings can only be used to measure inanimate objects. Let’s say your child is lying on the bed and you’re standing in front of him holding the thermometer into your hand telling him to wait unless the data appears on your screen. Most common ratios are 4:1, 8:1,30:1 and 50:1. The top image was taken with a 4x close-up lens, the bottom image with a 15 micron lens. It's Dust Resistant (IP54 certified) 3. Other infrared thermometers, like the one illustrated here, compare the heat radiation from the object whose temperature you're trying to measure with the radiation produced by an internal heat source (whose temperature is precisely known) or the background level of infrared inside the pyrometer's casing. The most common infrared thermometer is the spot infrared pyrometer or infrared pyrometer, which measures the temperature at a spot on a surface (actually a … Häufig sind Infrarot-Thermometern mit einem Laser ausgestattet. it can only be set to a value based on the ambient temperature of a room. As devices continue to get faster in processing speed, yet are required to fit into smaller packages, finding ways to dissipate the heat and identify hot spots is a real problem. The best thing about this thermometer is that it throws dual infrared laser on the object making it easy for the user to understand which part of the object is being measured. from transformers to steam lines, to hard to reach vents – anything is possible with the Fluke. The answer really depends on the application. In the situation where a thermal imaging camera is used to measure the temperature of a certain target we assume that the distance to the target equals the radius of the circle and we also consider the target to be rather flat. Whenever you need to operate the thermometer, simply press the trigger and it will measure the temperature of the object by throwing infrared light on it. Whether it is insulation leak, or a car cooling system – this thermometer can solve the problem before it even exists. A thermal imaging camera can be used to check heat dissipation on printed circuit boards, to do quality checks or inspect thermal impact in the automotive sector, or to do failure analysis in the lab. Best Infrared thermometers can be used in scenarios where the object is still moving, where it is surrounded by an EM field, where it is in a vacuum or controlled atmosphere or in applications where you need an immediate response. And when you’re measuring the temperature of an object/or surface, you need to point the thermometer towards that object/surface and press the trigger. Our high-quality non-contact infrared thermometers and pyrometers provide temperature measurement solutions and control from 0-2600 °C (32-4700 F) of industrial manufacturing processes. Advantages of Contact Thermometers over Non-Contact/Infrared Thermometers. surfaces between the temperature 14 Fahrenheit to 1472 Fahrenheit (between 50 degrees Celsius and 800 degrees Celsius) with an accuracy of +/- 1.5%.The Color screen makes it easy to read and the 12 point aperture automatically locks in at the distance to spot ratio. A modern pyrometer has an optical system and a detector. They may not be perfect for every temperature measuring job, but it is likely that you find plenty of occasions and ways to make an  best Infrared thermometer work for you. You can use it to check your engine, find leaks at home, find out the refrigerator temperature, or even use it to make soaps or candles. It can measure between minus 50 degrees Celsius to 550 degrees Celsius. If the design had included an element that made it easier to hang, it would be a handier tool. A 9V heavy-duty battery is included in the package which is perfectly suitable for home use. That means that the object of which you want to measure the temperature, also referred to as the target, needs to cover the entire spot size. It means you can use it to measure the temperature of a range of households such as food, water pipes, and ventilation. It does not measure ambient temperature accurately. Compare. Let’s take a look at the Etekcity Infrared Thermometer 774 and see how you can use this thermometer in certain conditions. Well, it’s an important feature that enables you to monitor the temperature of multiple surfaces in real-time. An infrared thermometer or pyrometer should be adapted to its intended use. Das ist zum Beispiel bei Wetterstationen der Fall, die uns dabei helfen, die Wetterbedingungen einzuschätzen. It is useful to detect leaks within the house – even those that are really small. The Etekcity lasergrip is made of plastic with a filling of a rubber plastic which is really soft. Right under the infrared sensors, you’d see a section where you can insert two AAA batteries to operate the thermometer. In the real world, there are no perfect thermal black surfaces and most objects have emissivity levels between 0 and 1. We tested this thermometer on an aquarium. The USB port does not have a software option. Simply, flip the cover and install the battery. Due to its ability to measure such vast temperatures as well as its distance to spot ratio of 12:1, the laser beam allows you to aim precisely at the spot you want to measure. So in theory covering one pixel in the thermal image should be sufficient to ensure correct temperature measurements. It is IP54 certified and is dust and water resistant. HFR researched 3 reasons why these devices are inaccurate. What we don’t like about this thermometer is that it cannot be recharged. The thermometer comes with a backlit LED display so you may easily check the temperature even at night. Then we tested the thermometer on different food items in our refrigerator. The auto shut off and low battery indicator allows the user to conserve energy and also takes accurate readings. whether you are trying to locate a heat source or measure the temperature whilst cooking. However, the features of these buttons are a bit different. Consequently, the smaller the target, the closer you need to hold the spot pyrometer in order to accurately measure its temperature. The rest of the buttons can be found on the back of the thermometer right under the LCD display. The MFOV describes the real measurement spot size of a thermal camera, in other words: the smallest measureable area for correct temperature readings. The thermometer is designed in the form of a laser gun to provide an extreme level of comfort to the user. The EC IR thermometer can measure temperatures ranging from -58℉ (-50℃) to 788℉ (420℃) with no contact. Infrared thermometers are most useful when measuring temperature in places where thermocouples or other sensors cannot be used to produce precise data. The emissivity is between 0.10-1.00 and is adjustable hence provides accuracy even if there are different materials. It is especially useful as it provides instant results, making the decision making process immediate. Choosing a pyrometer? The THZY can be used to measure surface, dew or ambient temperature or ambient humidity. And if you start moving the thermometer to another surface while holding the trigger, you’d see the temperature changing on the LED display. Best Infrared thermometers are mounted and used in industrial processes where they themselves are stationary. Etekcity Lasergrip 800 Digital Infrared Thermometer. The Champion is portable, accurate and easy to use without maintaining any contact with surfaces. The EnnoLogic is a professional gun that will give you accurate readings for many years to come. A recessed screw or a click would be indicative of a robust closure button. They measure the temperature of extremely hot objects based on the color of the visible light they emit. Close-up and microscopic lenses provide great image detail and allow you to measure small spots. With the EnnoLogic you can determine where the leaks are, check the A/C outputs, and even the cars brake system. And there are plenty of other benefits that make it one of the best infrared thermometers. The actual measurement need not be related to the spot at all. The sleek curved design looks great when you hold the thermometer in your hand. Not only is it FDA, FCC, CE and ROHS approved – but it is also powered by two AAA batteries that are a part of the set.
