Room temperature plus 20℃ ~ 350℃ (index parameter).
(The upper limit of the set parameter can be effective up to 399 ° C, which allows users to use it but does not guarantee
technical indicators) 。
Temperature control accuracy: not more than ± 0.1 ℃.
Temperature of the remaining heating zone：
Room temperature plus 20℃ ~ 350℃ (index parameter).(The upper limit of the set parameter can be effective up to 399 ° C, which
allows users to use it but does not guarantee technical indicators) .
Temperature control accuracy: not more than±0.2℃.
