This board allows connection of the included PT100 temperature sensor for better temperature accuracy and extended temperature range. The PT100 amplifier board amplifies the signal from your PT100 temperature sensor to a voltage level that your 3D printer controller can read accurately. Calibration values are already built into Marlin firmware (type 20) for our amplifier boad and PT100 sensor.

The custom made thermistor is encapsulated into an easy to use cartridge package.

Using PT100 Class B thermistors, which are then potted into a  cylindrical stainless steel cartridge with a high conductivity ceramic based adhesive. The legs are insulated with fibreglass sleeving, and terminated with a Molex Microfit 3.0 connector.
