details
1．High precision, with a maximum accuracy of± 0.06 ° C (± 0.11 ° F), using 4-wire resistance true value measurement technology
2．Excellent stability:0.01˚C
3．Better temperature consistency, the unique dual zone heating well ensures excellent temperature field consistency
4．Intelligent reference probe,The JOFRA reference probe is equipped with an intelligent connector and a built-in chip that stores calibration data (temperature correction parameters) and other information. This is a true plug and play calibration system
5．USB communication, all PTC type dry body furnaces can connect and communicate with computers through USB interfaces
6．Efficiency improvement, fast heating capability/Refrigeration effectively improves work efficiency. Rising to 350 ℃ only takes 7 minutes
7．Calibration work order function, using the work order function can achieve fully automatic calibration
