After reading the review about the temperature being way off, the first thing I did with this amplifier was perform an experiment using another calibrated temperature measuring device, calculate this amplifiers temperature slope, and compare it to the formula printed on the PCB.The data was surprisingly linear a temperature range of 120-20 degrees Celsius. There is about 2.4 to 2.8 degree Celsius error between the theoretical value (i.e. the calculated value based on the equation on the PCB from the output voltage) and what I measured. I'm not sure why the other reviewer had issues (maybe they were not using a K type thermocouple) but I would say being within a fairly constant 2 to 3 degrees is pretty good "out of the box."

Works perfectly for 3d printer thermocouple.

Works as advertised. The transfer function printed on the back is off like others have described. I had to come up with my own transfer function using a calibrated Fluke meter to compare. I ended up with T(Fº)=(367.12*Vo) - 432.81

It's complicated and might require soldering. I used the Saintsmart thermocouple amplifier instead and it works great.

Ich habe diesen Amplifier gekauft um PT1000 Sensoren auszulesen. Die erhaltene Genauigkeit lag bei +/- 8°c. Demnach total unbrauchbar für meinen Anwendungsbereich. Ich hoffe sie gegen MAX31865 eintauschen zu können.Die Genauigkeit von 8°c habe ich selbst mit einigen Wiederständen hinbekommen ohne dieses Modul.
