Principle
The test chamber drives the refrigeration and air circulation system through the brand Compressor and circulating fan, and uses the environmentally friendly refrigerant (R134a) to achieve efficient cooling. The environment in the box is detected by the dry and wet bulb or electric kiln temperature and humidity Sensor, and the heating, humidification, refrigeration and dehumidification modules are precisely adjusted by the fuzzy PID controller. Combined with the unique air duct circulation system, the temperature and humidity of the studio are uniform and stable. Multi-stage programmable control realizes the automatic operation of the complex temperature and humidity alternating test process.
Applications
Reliability test of electronic products, material weathering resistance test, environmental adaptability assessment of automotive parts, aerospace parts test, Stability study of chemical products, storage conditions simulation of pharmaceutical products, R & D institution environment simulation experiment

Steps
1. Place the device in a suitable location and connect it to a power supply (AC220V 50Hz).
2. Add water to the equipment through the built-in pull-out sink.
3. Operate the temperature and humidity controller through the keyboard or touch screen to set the required test temperature, humidity, and program steps.
4. Place the sample on the shelf and into the studio.
5. Start the equipment and the test starts running.
6. During the test, measurement or operation can be carried out through the test hole on the side of the box.
7. After the test, remove the sample and turn off the power of the device.
8. (Optional/standard function) Data can be exported through USB interface, or data analytics and report generation can be carried out through professional software on the computer.
Notice
• Before the equipment runs, ensure that the water supply is normal to avoid triggering water shortage protection.
• Do not operate beyond the device's limited Temperature range (-20~ 130 ℃, 30~ 95% RH).
• Pay attention to the equipment alarm prompt (such as overheating, Compressor overheating, etc.), and deal with it in time.
• When cleaning the box, the shelf bracket can be removed for easy cleaning.
• When using the touchscreen controller, the screen lock function can be enabled to prevent misoperation.
• The equipment is heavy (Net weight 213Kg), so pay attention to safety during handling and installation.
• To maintain Temperature Uniformity ( +/- 2 ° C) and Flexibility (+/- 0.5 ° C), do not overcrowd the sample.
