I have received 3 sensors, and set them up to compare to my Lab reference PT100. Found differences in resistance about 2.4 Ohms. And this translates to about 8 deg. of C - shift to the lower temperature. If using this sensor "as is" measured temperature of 21 deg. of C will be seen as 13 deg of C. (This problem also was reported by: tioted in 2015-07-29) To correct the problem, I have connected 2.4 Ohm 1% Metal Film resistor in series with the sensor. This corrected the problem but introduced some 2% of non linearity - which in most circuits is acceptable. If you are using MCU with PT100 Table in the memory, you can introduce the correction table, and solve the problem without any additional resistors - the elegant solution. This sensor price is 1/10 of the "perfect PT100" for the above reason of - it needs a little correction. Thanks Banggood.

I tested on my soldering iron and on room temperature. On soldering iron it is about 5°C off, but I am not sure whether soldering iron is accurate too. On room temperature, it is off by 2°C or less. Thanks.

For higher temperatures I will definitely use higher quality probe, but it will use a purpose for now I guess.

I will use the water temperature sensors in the aquarium. I would also like 1000 ohms for solar panels.

Sonde con rapporto qualita' prezzo molto buono , precisione non eccellente, costruzione e ingombro buona...con tutti i limite delle pt100 a due fili.

After I calibrate & linearize the critical band of temperatures, I use this sensors and runs fine. After 12 days of running the results were good for variation & accuracy,

if you want a PT-100 sensor that Works wery precice you will not be disapointet this sensor is good walue for mony
