Banggood

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

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.

All good. Banggood !

Arrivato funzionante :)

quality product

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

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,

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

Reliable and well insulated temperature sensor. with its relatively small diameter fit even 2 sensors in a normal dip tube. So you can evaluate and process the same measurement at two different locations.

Well produced PT100 temperature sensors. A ADC is needed to get readings on the computer but there are many solutions to be found. A small Arduino board or a DS2450 ADC for a 1-wire set up will do the trick.
