Title says it all, these work great with arduino. Quality seems solid 10/10 would buy again and probably will.

I think it’s a good product

Not the fault of AITRIP, but the MAX6675 isn't what I expected. It doesn't measure temperatures below 0C. It does have a nice measurement range, albeit for high temperatures.The boards and probes were all of reasonable quality and priced decently. I just couldn't use them for my application because of the low end measurement range.

Cheap and effective. The physical cold junction is replaced by a silicon based one in the 6675 chip. These are generally accurate to +/- 2C. So long as the screw terminals on the module module are at the same temp as the chip the issue of junctions at the screw terminals should not be an issue at all.

This product is pretty much how it is depicted and advertised. I was able to connect this to an Arduino and write some code for basic temperature measurements within a few minutes of receiving it. It was also very convenient that I could get it next day.Note that the ad copy is a bit deceiving if you don't know what you're getting. The product description does say that it has "cold junction compensation circuit" which may be technically accurate (the integrated circuit chip on the printed circuit board may have this capability) but this product does not use cold junction compensation. I had assumed this from looking at the pictures and from the low price, and this will work OK in my application, so it's no problem for me.However, you should be aware of this fact: the connections from the wire to the crimp-on connectors to the screw terminal form multiple thermocouples, and these affect the reading. You can at least partially compensate for this with a simple calibration in software (especially if you can hold the connector block at a constant temperature), but be aware that a change to the temperature of the screw terminal will change the thermocouple reading, and this change is not so easy to compensate for without a proper cold junction terminal block.In the case of my low-cost controller, the changing junction block temperature might cause a change in reading of 10 - 15 F degrees, and that's not a problem for measuring the approximately 300 degree F temperatures in this particular application. But if it matters in your application, you may want to spend some more money and get modules with cold junction compensation properly implemented.
