Principle
The equipment is heated by a nickel-chromium alloy electric heating wire heater and humidified by a stainless steel sheathed heater. The refrigeration system adopts a French Taikang fully enclosed or a German BITZER semi-enclosed Compressor, uses environmentally friendly R404A and R23 refrigerants, and achieves rapid cooling through air-cooled single-stage or cascade refrigeration. The centrifugal fan is used in the box with a broadband forced air circulation (up and down) to ensure uniform distribution of temperature and humidity. The control system collects data through a PT100 temperature sensor and an imported wet and dry bulb humidity Sensor, and is precisely adjusted by a multi-stage program temperature control system.
Applications
Reliability test of electronic products, material weathering resistance test, environment simulation of auto parts, Stability inspection of pharmaceutical products, performance evaluation of chemical products
Steps
Connect the power supply (AC220V +/- 10% or AC380V/415V +/- 10%).
2. Set the required temperature, humidity and program through the touchscreen controller.
3. Select the running mode (e.g. fixed-value running or program running).
4. Start the equipment and start the experiment.
5. The experimental process can be monitored in real time through the observation window.
6. After the experiment, the device can be automatically stopped or manually stopped according to the setting.
Notice
• Power supply voltage meets equipment requirements (AC220V +/- 10% or AC380V/415V +/- 10%).
• When the equipment is running, do not open and close the box door frequently, so as not to affect the stability of internal temperature and humidity.
• Regularly check the water supply of the humidification system to prevent dry burning.
• Pay attention to ventilate around the equipment to ensure good heat dissipation.
• Non-professional personnel should not disassemble or repair the equipment.
The equipment is equipped with multiple safety protections, but it is still necessary to observe the alarm information during operation.
• When moving your device, use the built-in pulley to push smoothly.
