本儀器采用復(fù)疊式制冷循環(huán)方式,由兩個單壓縮機(jī)循環(huán)疊加制冷。通過加熱管實(shí)現(xiàn)溫度控制,由智能控溫儀表電路實(shí)現(xiàn)定點(diǎn)控溫。智能數(shù)顯溫控儀具有PID自整定功能,使控溫點(diǎn)達(dá)到更高精度。
一、控溫范圍:0℃~-75℃
PBD0090 freezing point tester
The instrument adopts a cascade refrigeration cycle, which is superimposed and cooled by two single compressor cycles. The temperature control is realized by the heating tube, and the fixed temperature control is realized by the intelligent temperature control instrument circuit. The intelligent digital display temperature controller has a PID self-tuning function to achieve a higher precision of the temperature control point.
The instrument has the following features:
First, the structure is compact, the shape is beautiful, and the operation is convenient.
Second, non-contact electromagnetic stirring has a long life.
Technical Parameters
