DRT Series Electric Heater (Heating Cover) preserves heat with a half-ball heat preserver made of light heat preserving cotton s

Feature:

1.It adjusts pressure with big power thyristor,controls lines with relay,achieves constant temperature effect combined with contact thermomemter.It can accurately control temperature .Light and flexible,it is an ideal product to substitute heavy coil pressure regulator controllig electric cover.

2.The display adopts concentrated circuit controlling and electric thermo-couple temperature sensing,digital display dial thermometer.It is possible to preset required tmperature.The electric cover will maintain constant temperature to heat as soon asthe preset temperature is reached.Different from other electric covers,it can alternatively display temperature within controlling electric cover and temperature of liquid at the bottle bottom.It has the characteristics that temperature controlling is accurate,temperature display is visual,operation is easy,time and efforts are saving.

3.DRT-ZN series,with the chip of computer as main control unit,use multiple digitalfilter circuits and fuzzy PID control method,have the advantages of high measurementaccuracy,slight impact temperature,single key slight-touch operation,two-screen display,internal and external electric thermo-couple temperature measurement,siliconcontrolled output,and have circuit-breaking protection function,it is the most ideal instrument for making accurate control-temperature heating experiment.
