1, cabinets are made of stainless steel welding, outer box made of high quality steel, beautiful appearance, novel. 2, the use of bias over temperature protection with a digital display microcomputer PID controller. Unique level constant temperature control, can be high-precision, high stability temperature control. 3, hot air circulation system consists of continuous operation in high temperature fan and duct reasonable composition, improve the indoor temperature uniformity. 4, the synthesis of silicon using the new seal, long-term high temperature operation, long service life. Standard: a very wide range of temperature control can meet GB/T2423 "testing procedures for electric and electronic products." Meet ISO0188, ASTM-D3012, ASTM-D5423 standard. Technical Data: Temperature Fluctuation: ± 0.5 ℃; temperature uniformity: ≤ ± 2 ℃; temperature deviation: ≤ ± 2 ℃; by the Japanese original Fuji digital temperature control.
