Helect Digital Infrared Thermometer -50°C to 550°C with LCD Display

Works great, hood quality and accurate. Its easy to use, put the battery in and go. The littlies and hubby had lots of fun taking the temperature of everything, cats, dogs, radiators you name it.

Not sure if it reads completely accurate but for the price it seems to do the job, I use it for curing screen printing ink, pretty good overall!

The device is easy to use: simply hold trigger to get continuous readings (scan) with 1/2second lag - so scan slowly. Release the button and it will hold the last reading - useful when taking a reading and are unable to see the display. The display has a on/off backlight to assist if needed. I have tested this on various known temperatures (fridge, freezer, icy water, boiling water) and readings are reasonably accurate. Beware: on my device the laser-spot is way off the alignment of the gun (a good 12cm out at 3meter distance), so be cautious if taking measurements at a distance. Also be aware that the 'cone' of the IR detector has field of view of 12:1, so at 3 meters distance it will show the temperature for a 250cm diameter area. So to get an accurate reading for a small area you need to be close to it. Finally:, different materials/surfaces have different IR Emissivity Values in that a matt-black surface will display a higher IR reading than a white or reflective one. The instruction leaflet provides an Emissivity Value table for various materials, but it fails to explain how to use them. I am of the understanding that you DIVIDE the displayed reading by the Emissivity value (always less than 1), so that the actual/calculated temperature will be higher than that displayed. I'd happy give 5 stars if the guidance laser was more accurately aligned to the physical hand-gun, although the separate IR detector could also be misaligned. And slightly better instructions.

Used it to pick up draughts around doors and windows, very good product

Fairly accurate temp readings very good for price.I work in asphalt industry and have misplaced my works temp gun which was expensive this seems to be on par and a good price.

Might not have really accurate temp.

Since we are in a heat spell I thought I check on how our air conditioning is doing. Since my intake is so high we decided for the convenience we would purchase the Helect Non-Contact Digital Laser Infrared Thermometer. And boy are we pleased. Read on for our observations when using the Helect Thermometer. -- ACCURATE: I read the difference between the AC intake and output should be a minimum of 14 deg F. At first I drug the ladder in the house, reached as high as I could to tape a analog thermometer on the intake and then the same thing on the output vent. We later compared those readings to the Helect Thermometer and saw the same temperature readings. We measured at other locations where a thermoter was already present such as the house thermostat, outside thermometer and great, we got the same readings everywhere! -- LONG REACH: What a convenience to stand on the floor, point the thermoter whereever you need and get an accurate reading. In our case we made measurements up to 25ft away and found them to be accurate. -- LOVE THE LASER: The laser is bright and easy to find, especially inside and really essential to be able to pinpoint the spot on which you need to measure. -- COULDN'T BE EASIER TO USE: Just point, pull the trigger, position the laser dot on the area to measure and within 1 second you have a reading. When the trigger is held down the reading will continue to reflect the spot where the laser is, even when moving it side to side to make comparisons. CONCLUSION: Could be simpler to use and amazingly accurate. What a great value for such an incredible convenience!

Ich war auf der suche nach einem günstigen Infrarot-Thermometer, da ich ein solches für ein kleines Projekt benötigte. Demzufolge war ich nicht bereit viel Geld hierfür auszugeben und meine Wahl fiel schnell auf dieses Produkt. Es ist einfach zu bedienen, der Laserpointer lässt sich an- und ausschalten, genauso wie die Hintergrundbeleuchtung des Displays.Hinzukommt, dass die maximal und minimal gemessene Temperatur angezeigt werden kann. Allerdings sollte man sich beim Kauf bewusst sein, dass dies kein Präzisionsmessgerät ist, wer also die Temperatur auf einen Zehntel Grad genau wissen will, sollte eventuell auf ein professionelleres Gerät zurückgreifen. (Das Gerät zeigt die Temperatur zwar in Zehntel-Grad Schritten an, die tatsächliche Abweichung liegt allerdings höher, ich glaube es war bei etwa einem °C, was man einem Gerät dieser Preisklasse aber nicht ankreiden sollte) Auch misst das Gerät nicht exakt am Laserpunkt, sondern etwas weiter darunter, wenn man dies allerdings weiß, stellt das keine Probleme mehr dar. Was mich in dieser Preisklasse ebenfalls überraschte war, dass ich eine Lebenslange Garantie des Herstellers auf dieses Gerät erhielt, was etwaige Bedenken über die Lebensdauer des Gerätes betraf, beseitigte. Ich kann dieses Gerät somit jedem wärmsten empfehlen, der ein Infrarot-Thermometer mit gutem Funktionsumfang und guter Verarbeitungsqualität für kleines Geld sucht. Als Abschluss möchte ich noch erwähnen, dass ich noch nie ein Profi-Infrarot-Thermometer benutzt habe und ich das hier gekaufte somit nicht mit einem solchen vergleichen kann.

Per ora sembra funzionare molto bene.
