2. Quality assurance: imported brand Compressors and circulating fans make uniform temperature distribution, high efficiency of environmentally friendly refrigerants and low energy consumption to promote energy saving, unique air duct circulation system to ensure uniform working room temperature Humidity, imported 304 mirror stainless steel liner Four corners and a half arc over, shelf bracket can be freely loaded and unloaded for easy cleaning, multi-stage programmable control simplifies complex test process to achieve automatic control and operation.
3. Safety function: independent temperature limit alarm system overrun automatic interruption and sound and light alarm, high temperature and low temperature and over-temperature alarm, Compressor overheating overcurrent overload protection, fan overheating protection.
4. Convenient data processing (optional): can be connected to a printer or 485 Communication interface, with USB data transfer interface (SD disk), with a computer to display and print Humidity and Time Linear dispersion, for the test process data storage and playback to provide assurance.
5. Programmable Touchscreen controller (standard): Color LCD touch screen Menu Operating interface Observation intuitive and easy to operate, Chinese and English Operating interface Optional screen display Instant temperature Humidity Run Linear dispersion, can be set up 120 groups Each group of 99 segments 999 cycles Each segment can be set for 999 hours 59 minutes 59 seconds, with screen lock function to avoid human touch to change data or stop, with P.I.D automatic calculation function to correct temperature Humidity changes for accurate and stable control, with RS-232 or RS-485 Communication interface can monitor the test process and execute the switch machine in the computer design program, install professional control software to monitor and control 30 devices at the same time, computer real-time analysis and storage of data to form Excel or Word documents for easy printing.
Principle
The test Chamber achieves high-efficiency refrigeration through imported brand Compressors and environmentally friendly refrigerants, combined with a unique air duct circulation system and circulating fan to ensure uniform temperature distribution in the studio; adopts imported temperature Humidity controller and programmable Touchscreen control to achieve accurate temperature Humidity regulation and automatic operation; safety system includes independent temperature limit alarm and multiple protection mechanisms to ensure experimental safety.
Applications
High and low temperature testing, alternating environmental testing, Reliability verification, material performance evaluation, electronic component testing, automotive parts testing, aerospace parts testing, scientific research experiments
Steps
1. Connect the power supply (AC380V 50Hz).
2. Enter the Humidity parameter through the keyboard or Touchscreen, and set the number of programmable segments (up to 120 groups of 99 segments per group).
3. Start the equipment and run the test.
4. Use the test hole for experimental operation and temperature measurement.
5. Monitor the running process and analyze the data in real time through computer software.
6. At the end of the test, turn off the equipment and clean the liner.
Notice
● Power supply voltage AC380V 50Hz to avoid voltage mismatch.
● Check whether the test hole is smooth before operation to prevent blockage from affecting the measurement.
● Temperature range (-40~ 130 ℃) is not exceeded when setting temperature parameters to prevent over-limit alarm.
● Regularly clean liners and shelves to maintain equipment hygiene.
● Use the screen lock function to avoid unauthorized data changes.
● Pay attention to Compressor overheating, overcurrent and overload protection, and deal with abnormal situations in time.
When connecting a computer or printer, ensure that the interface is compatible to avoid data loss.
