High and Low Temperature Testing Machine

Constant temperature and humidity test machine is also called environment testing machine, used to test various types of materials for their tolerances of heat, cold, dry, humidity. Application: Quality inspection for all types of electronic products, electric appliance, and products from communication,

instrument, automobile, plastic, metal, food, chemical, building materials, medical and aerospace industries.

Watt / Power / Current

Maximum watt

7.5KW

Maximum current

9A

Power supply requirement and source

1)AC 380V three phases with four wires +protective grounding; voltage fluctuation range 10%

2)Frequency fluctuation range:50±0.5Hz;

3)Power supply method: TN-S or TT method

4)Grounding resistance of protection ground wire＜4Ω

5)User should equip with relevant capacity air switch or dynamic switch on the installation site, and the switch must control this machine only. When the electrified test sample is put in the test chamber, the power of the test sample should be connected with extra power, don’t use the power of this machine;

Performance Index

Environment requirement

The data got under the condition of environment temperature is +25℃,and R.H. is ≤85%,no test sample in the chamber.

Temperature range

temperature range:+25℃～+150℃

Control accuracy

temperature resolution:0.01℃         temperature deviation: ±1℃                  

temperature uniformity:≤2℃          temperature fluctuation:±0.5℃                  

Heating /cooling

rate

+25℃→+150℃≤45 min

+150℃→+25℃≤10 min

Note: Steel heat capacity ≤35kg/m³ ;when humidity time, no heat resource;

Note: performance index above is under the condition of environment temperature is +25℃,

and R.H. is ≤85%,no test sample in the chamber;
