I have had this meter for a few years now. It has been used on many different jobs including setting up domestic heating systems, measuring car engine water temperature and on a Jet aircraft engine!Still functioning perfectly and the thermocouples are easy to obtain or make yourself.

Good product, react as advertised, good precision. Bad reviews here (concerning BIG errors in measuring temperature), are made by guys that do not pay attention connecting sensors (including me, for a while (: ). There is a "+" and a "-" written on the sensor connector and on the device.After correctly connected and testing temperature (by putting all sensors in a plastic bag, near one to another) all had same indication (17.3C), two of them stable and two of them slowly changing indication from 17.2 to 17.3C and back. Changing the connection port of the 2 "unstabled" sensors did not affect the indication, but the position in the plastic bag did. As a result, I concluded the there is a VERY GOOD calibration from factory, the sensors are (at least at delivery time) ABSOLUTELY THE SAME, interchangeable.Be careful not to modify connector temperatures (by hand by example) as this will generate erroneous signals, and be displayed by the device.If needed to be used at another (very different) ambient temperature than 20C (or 21C - I don't remember), it may be possible to re-calibrate the device, as per instructions (for exemple to be used outside at -15C or at +40C). At such distant temperatures, the connectors (the contact between device and sensor wires) will generate enough erroneous TEM voltage to fail your precision of the measurement. Also, as per manufacturer recommendations, let device 30 minutes in the ambient BEFORE measuring, to minimise the gradient of temperatures inside the device.Another observation is that in the first 5-10 seconds after power-up there is a different indication (few 0.1C) more then displayed later, when it became stable. I suppose stable temperature is good, as this is how the calibration was done. (as self-explained, it may be a "mini-heating" of the probe by the measurement itself or by powering-on - this is documented and normal for measuring with thermoresistance - but somehow applied to thermocouples).

La précision des mesures est tout a fait acceptable pour mes applications (environ 1% pour l'appareil que j'ai reçu). La qualité de fabrication est correcte, sans plus, mais tout à fait en rapport avec un appareil à ce prix. Les 4 canaux sont un plus indéniable et les capteurs de type K livrés avec l'appareil permettent une mise en œuvre rapide pour se faire la main (prévoir tout de même des capteurs plus robustes pour une application réelle).

Very useful when you need to measure multiple temperatures in a machine, assembly, or for instance, under the hood of a performance car, in different locations, but all at the same time. Accepts all common K type thermocouples with the yellow plug. Remember that a thermocouple thermometer reads resistance in the sensor. So to have the same calibration in all four thermocouples, you need to use thermocouples with identical length wire. If the lengths are different, you can introduce an off-set in the software, but it is simpler just to use four thermocouples all with the same length. Four thermocouples are provided, but these have low temperature jacketing on the wire, so you cannot use them, for instance, to measure exhaust manifold temperatures on a car. With better quality shielding, these kinds of temperatures are within the standard range of this unit.

Valeur fausse, au moins 4 degrés d' écart en température négative, même en changeant les sondes, complètement déçu de cet appareil

Funktioniert einwandfrei, die Bedienung ist selbst erklärend (sollte sie aber auch sein, da keine Anleitung mitgeliefert wird). Min/Max- sowie Durchschnittfunktion arbeiten jeweils pro Kanal. Sehr gut ablesbares Display. Abweichung der Messwerte untereinander bei 0,1°C. Besser geht es gar nicht. Ich wüsste nicht, warum man ein teureres Gerät kaufen sollte.

I can't understand the negative reviews. I was skeptical but needed to fill this order as inexpensively as I could. I purchased this feeling that I would no doubt have to replace it soon after purchasing. But, at this price I considered it "disposable" and didn't worry to much.Without going into unnecessary details, my unit takes fearsome abuse. It is regularly checked against two analogue standards and is working much better than expected! It has never failed to deliver rock solid performance on all four channels. Given all four probes are identical, each reading from the same location is the same (given the units stated tolerances)It could be that quality control is lacking, that I got a lucky break and the others maybe more unlucky. However, I now have need for a second unit and will be purchasing another. We'll see how I do.Edit:Second unit purchased. In use for six months, perfect just like the first. Keep in mind, the second unit was purchased more than a year after the first. If there were a quality control problem, odds are good I would have seen a problem with one of the two units. This leads to me believe the negative reviews on this item are not be taken seriously.Edit: Years of daily use, both going strong. These units take serious punishment and keep working. Highly recommended!EDIT: Three years later, both working strong. Better yet, compared with a colleagues much more expensive unit, these units have proven to be more accurate. More consistent when measured against analogue standards.

Update 04-07-2017Ive been using this for while and still think its great.I just figured out that you can turn off the auto power down feature.First turn off the unit then hold the HOLD button down and turn it on. You only need to press the power button but keep the HOLD button pressed until it turns on.The auto power off icon is now gone from the display and it will remain on until you turn it off.The auto power off will come back the next time you turn it on.I really like this 4 channel thermocouple temperature meter.It was really easy to figure out how to use it and set it up for reading my film drying cabinet.It feels good in the hand, though i did mount it to the cabinet so i don't have to keep unplugging the thermocouples.It has Min/Max/Avg modes, they work great. The backlight has a hotspot and isn't totally even, not a big issue.It can also switch between C, F and K. Really useful. Turns on and off fast, readings are accurate (within the variance of the probes).Only complaint is the LCD doesn’t have a large viewing angle. Its only readable from a few angles.I have it up a bit above my head, so i look up at it. That’s a perfect viewing angle and the numbers are crisp.Other than that, i would highly recommend it. The price is good and the features, namely 4 channels cant be beat.

I work in the refrigeration industry, and figured I would give this thermocouple a chance purely based on the price point. The ability to connect four probes would cost a small fortune with one of the name brand devices. Purchasing two of their dual-probe units is way out of the budget. So I'll just break this into Pros and Cons.Pros:- Low price point.- Has all of the measurement features you would get from the $200+ units.- After troubleshooting against our more expensive lab equipment (details below), was able to achieve similar results.Cons:- I'm not a physicist, but I learned how thermocouples work when troubleshooting my accuracy test. "Thermocouple thermometers are composed of two conductors, usually alloys of the same metal, which touch at the sensor end of the thermometer. The difference in conductivity between the two metal pieces produces a voltage flow between the sensor end and the open end of each conductor, which can be used to determine the temperature." One challenge with this device is that the probe connection point has no means to shield itself. Therefore when I left the Thermocouple inside the refrigerated display, the conductivity increases in the metals and returned an inaccurate reading (far colder than actual). After letting everything warm back up that should be, when a similar test was done with the thermocouple outside of the refrigerated area, the device was within 0.2 degrees F of our lab testing equipment when measuring in the -10 to +30 degree F range. Relatively simple solution, however more the far more expensive thermocouples I've used don't have this issue. Solution: Purchased 6' probes (cheap, and also much better quality that the probes included).- Like another reviewer, one of the internal screws that mounts the internal board to the case mounting points was bouncing around inside when i opened the box. When I fixed it, it seated perfectly, so I'm not sure how it's possible to come free like that. Easy fix, but you'd think that someone would have noticed before putting the "QC" sticker on the device...
