Coffee bean roaster accessories: introduction of HB-L2 coffee roasting brand pt100 bean temperature probe
Color classification: K-type PT100
Name: pt100 bean temperature probe imported from Heraeus, Germany
Specification: M600060 wire length 1.5m
Suitable model: suitable for measuring bean temperature and hot air temperature of HB-L2 coffee roaster
Brief introduction:
The sensor we use is Heraeus high-grade platinum resistor, which is one of the core components of the coffee roaster.

The metal part of the front probe rod is food grade 304 stainless steel, which can effectively control the non-polluting food.
The temperature measuring line is a two-wire system of high-temperature silver plating (inside two-core silver-plated wire, silver-plated shielding wire). The tetrafluorine outer skin can withstand high temperature up to 180 degrees. This line is suitable for waterproof, imitating, corrosion and acid resistance, which ensures the maximum accuracy of temperature measurement in extreme environments.
Temperature measuring range
About-70 to 450 degrees Celsius
To test the resistance, you need to use the same 2-5 resistors to test. Put the resistors in the same water for heating. First, prepare an insulation cup and add a mixture of water and ice (2-5 minutes later, the temperature is 0 degrees). The resistance value is 100ohms, and the PT-100 is tested with a multimeter (calculated at 0.385 ohms 1 degree). The resistance value will rise by 0.385 ohms. Similarly, if the resistance error is small, the quality will be good.
