 Features:

1 Using semiconductor heating and cooling
You needed to set 45 ℃ lower than the ambient temperature to a maximum of 110 ℃ operating temperature without using Freon refrigeration. Its temperature accuracy, stability, rapid heating and cooling, energy saving, environmental protection and other portable devices comply with design specifications.

2 Small, portable size
Only 268 × 125 × 256mm size, contains a warm tank temperature control system, cooling and power supply system, convenient for field and field use

3  Variety of power supply 

Use 220VAC / 50HZ and 12VDC DC power supply, and the machine has a battery charging circuit can 12V / 7Ah Lead Acid batteries. Also has a variety of man-made wrong connection protection.

4  Rapid heating and cooling
Rose from 25 ℃ ambient temperature is about 110 ℃ time required eight minutes; dropped from 110 ℃ 0 ℃ about the time required for 18 minutes; This performance is particularly suitable for temperature switch inspection and verification.

 5 Optional four-hole composite bushings and large-diameter liquid-filled tube
4-hole composite casing with good thermal conductivity properties, with 8 ", 1/4" and 3mm, 6mm deep in more than just convenient than checking the thermometer. Large diameter casing can be used for filling non-standard temperature probe, can greatly improve the heat transfer characteristics.

 6 Precise PID temperature controller
PD-1020 dry asanas temperature calibrator is equipped with precise digital PID temperature controller can control the tank temperature fluctuation at ± 0.02 ℃.

 7 Excellent uniformity of temperature field
At 0 ℃, between two levels of temperature field uniformity is about ± 0.03 ℃.

 8 The rate of temperature control can be achieved
When users need to change the cooling rate, PID temperature control can be changed according to your requirement rate of temperature change, which switches for industrial temperature calibration is very useful.

9 Green energy
Without using fluorine refrigerant, in line with world environmental agreements.

10 Environmental conditions
PD-1020 is in accordance with the temperature of the laboratory environment and the general industrial design field conditions. Not waterproof, should be used in the absence of deflagration conditions.
