**Constant Temperature and Humidity Test Chamber – Price, Description, and Pre-Operation Checklist**
Before starting the operation of a constant temperature and humidity test chamber, it's essential to perform a thorough inspection to ensure safe and accurate testing. Here is a detailed guide to help you prepare the equipment properly.
1. **Power and Ground Line Check**:
Confirm that the power supply is stable and the grounding line is properly connected. Ensure the power cable is connected according to the manufacturer’s specifications and that the device is grounded correctly to prevent electrical hazards.
2. **Overtemperature Protector Check**:
Verify that the overtemperature protector is functioning properly. This component is usually pre-set at the factory and typically does not require adjustment unless specified by the user or after maintenance.
3. **Replacement of Wet Bulb Wicking Cloth**:
If the surface of the wet bulb wick becomes dirty or hardened, it should be replaced immediately. It is recommended to replace the wick every three months. Before installation, clean the area with a soft cloth and make sure the new wick is thoroughly moistened before placing it in the chamber.
4. **Inspection and Adjustment of Wet Bulb Water Level**:
The water level in the wet bulb reservoir must be carefully maintained. Too much water can cause overflow, while too little may prevent the wick from absorbing water properly, affecting the accuracy of the humidity readings. The water level should be kept at approximately 6 mm, and the reservoir can be adjusted accordingly to maintain optimal performance.
The test chamber is constructed using high-quality SUS stainless steel, machined with CNC technology for precision and durability. The exterior is sleek and elegant, offering a professional look. The inner chamber is made of SUS304 stainless steel, featuring a smooth, mirror-like finish that is easy to clean and resistant to corrosion. A blower duct is installed at the back of the chamber, housing components such as heaters and refrigeration evaporators. Two air circulation systems are integrated to ensure even distribution of hot and cold air throughout the chamber, maintaining consistent temperature and humidity levels as required during testing.
