Adafruit MAX31865 RTD PT100 or PT1000 Amplifier

PT100 & PT1000 Cruisin'

To get precision and accuracy out of your platinum (PT100 or PT1000) RTD you must use an amplifier that is designed to read the low resistance. Better yet, have an amplifier that can automatically adjust and compensate for the resistance of the connecting wires. If you're looking for a great RTD sensor, today is your lucky day because we have a lovely Adafruit RTD Sensor Amplifier with the MAX31865 breakout for use with any 2, 3 or 4 wire PT100 RTD!

Adafruit MAX31856 Universal Thermocouple Amplifier

Now you can handle any kind of thermocouple!

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we've suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we're happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy! This converter communicates over 4-wire SPI and can interface with any K, J, N, R, S, T, E, or B type thermocouple
