Dry Block Temperature Calibrator

Description:

PD****0 dry asanas temperature calibrator, through the design of its small portable size sophisticated; simple operation; facilitate field work site and place no AC power supply *4V DC power supply can be used in the design, particularly applicable to all kinds of temperature sensors, direct-reading thermometer gauge in place, and all kinds of temperature switch maintenance, inspection and field verification and comparison of short branched temperature probe calibration.
Use PD****0 dry asanas temperature calibrator can simulate an actual temperature in situ source, used to discover or suspect that you provide a true and accurate temperature measurement system verification program. For require periodic calibration, inspection measurement system may be exempted from the component disassembly trouble and retrieve laboratory validation errors may occur.

Features:
1 Low-voltage DC power for heating and air temperature screensavers
As a result of low-voltage DC *4V power heating, will eliminate the interference due to the exchange and electrostatic induction caused by high-voltage discharge. Suitable for static and AC induction there is a requirement.

2 Small / portable volume
Only **8 × **5 × **6mm 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 **0VAC / *0HZ and *4VDC DC power supply, and the machine has a battery charging circuit can *4V / 7Ah (or two *2V / 7Ah) Lead Acid batteries. Also has a variety of man-made wrong connection protection.

4 Rapid heating and cooling
From ambient temperature *5 ° C to **0 ° C takes about *8 minutes; from **0 ° C down to *0 ° C takes about *5 minutes; This performance is particularly suitable for temperature switch inspection and verification.

5 Optional four-hole composite bushings and large-diameter liquid-filled tube
*-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, tapered design, high temperatures are not easy to jam.

6  precision PID temperature controller
PD****0 dry asanas temperature calibrator is equipped with precise digital PID temperature controller can control the tank temperature fluctuation at ± 0.*2 ° C.

7 Excellent uniformity of temperature field
At **0 ºC, between the two levels of temperature field uniformity is about ± 0.*0 ºC.

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.
