Fluke - FLUKE-561 561 HVAC Pro Infrared Thermometer, -40 to +1022 Degree F Range

Velcro KTC is a bad brand. Overall, the unit is quite nice. The readings from the infrared camera are quick and precise. If that's your main use, this device will suffice. br>br>However, the included K Type Thermocouple (KTC) is, in a word, terrible. Because it is capable of giving VERY inaccurate readings, you must wrap it very tightly. It wanted to tell me that the hot water coming out of my boiler was 125 degrees, for example, when I was reading the temperatures on it. when the temperature in the boiler reached 180 degrees Fahrenheit I can tell you it's a lot more than 125 by touching the pipe. Slowly repositioning and tightening the Velcro resulted in readings in the 170s, which I think I can believe. If you're thinking about buying this unit and you really need the KTC, I'd think twice. Read the reviews of the Fluke Velcro KTC accessory on Amazon if you're not convinced what I'm saying is correct. br>br>I gave up and spent the extra $160 on the KTC pipe clamp, which is compatible with this unit and has excellent reviews. br>br>It's a real shame Fluke included such a terrible KTC.

The Fluke 561 single laser beam IR thermometer with a Type K thermocouple input is one of my favorites. It has adjustable emissivity and is based on the same core structure as Fluke's higher-priced 56X series IR thermometers. Its IR precision specification is /-. 1%, in relation to 2% for the majority of other single-beam IR thermometers. The IR lens and housing are one of the most important parts of any IR thermometer. The lens housing on Fluke's 56X series is solid metal, unlike most similar units, which are made of plastic. Overall, the 561 is a solid piece of equipment that I enjoy using. br>br>Of course, the fact that it is a main-frame computer is another important feature. Fluke unit should be connected to a Fluke-compatible computer. Housing that is yellow! I have to admit that I believe in and respect Fluke's reputation for high quality. I'll generalize and say that Luke's products cost 2/3 more than most similar units, but they are 50% better in terms of performance and longevity than most similar units. I used to shop solely on the basis of price; for example, I started out with a very good Craftsman multimeter that I knew was actually a re-manufactured item. Fluke 15B, which was originally designed for non-commercial use, is now housed. Market in the United States of America Later, I spent more money on a Fluke 177, which is a mid-range instrument like the 561. The level unit is built on a high-quality core structure. My first infrared thermometer, a great unit from Thermoworks, was a re-use. The Dwyer IR3 thermometer is housed in a unit made by whoever makes the Dwyer IR3 thermometer. By the way, I have yet to find another company that produces a product that compares to Thermoworks' excellent Thermapens. br>br>Like Fluke's 177 multimeter, I believe my 561 IR thermometer is of excellent quality, and I have no reservations about using it.

This product delivers on its promises and is simple to use. Thank you for some of the other reviews, as well as the centigrade - an added bonus by Fluke. The location of the Fahrenheit switch was made simple to locate. I've used it on mobile air conditioning and heating systems and am very pleased with its performance; I intend to use it on other systems as well.

When compared to other temperature sources, this is a simple to use thermometer that appears to be very accurate. It's what I use to check the ceiling heating elements for consistent heat radiating from an unseen source.

Instead of spending $30 on a cheap Chinese thermometer, I decided to invest in a good IR thermometer. It works flawlessly and comes with a nice carrying case and thermocouple.

br>I tried cheaper brands, but they seemed to read lower than I expected, so I did some research for at least three months before settling on a Fluke 561. br>I will not use any other unit; this one works flawlessly, with good solid readings and no fluctuation, unlike the others, which would change by at least twenty degrees if you held it in one place. br>On my five-cylinder radial engine, this unit provides consistent, accurate readings, allowing me to adjust my air baffles to keep all cylinders at a similar temperature. br>I've also come up with so many other uses for it that I could write a book about it. br>With this one, you can't go wrong.

This set is excellent for checking the temperature coming from vents. It's also convenient to have a probe to use on the lines to calculate superheat and supercool, but the probe is designed for larger diameter pipes, making it difficult to use on 1/2 or 1/4 pipe. A clamp-on probe would have been extremely useful.

The Fluke equipment is serviced on a continuous basis. br> The "sensing gun" (visual line-of-sight) for remote infrared temperature reading. br>The Infrared sensing element has a better stated temperature accuracy than the Asian versions and a tighter(lower) angle of infrared vision. It also has a K thermocouple plug in for checking the temperature at a given point or where you can't get line of sight infrared and want to check the change in that temperature over time. br>There is no operational data from a relative on how things are going in the field.
