Precautions for maintaining constant temperature and humidity chamber

1. The test cloth should be replaced every two to three months. The temperature measurement body should be wiped with a cleaning cloth when replacing. The new test cloth should be cleaned first. When the surface of the test cloth is not clean or hard, the test cloth must be replaced before the temperature and humidity sphericity control.

2. The water level of the accumulator should not be too high, so that the water overflows the accumulator or is too low to make the wet ball test cloth absorb water abnormally, affecting the accuracy of the wet ball. The water level should be kept about six points full. The water level of the water tube can be adjusted to adjust the height of the water box: adjust the screws on both sides.

3. Inspection and maintenance of the humidifier. The water stored in the humidifier should be replaced once a month to ensure clean water quality. The humidified water tray should be cleaned once a month to ensure smooth water flow.

4. Removal of condenser dust: regular monthly maintenance, use a vacuum cleaner to absorb the dust attached to the condenser cooling mesh or use high-pressure air to remove dust.

5. Check the over-temperature protector. When the machine is running, the maximum value of the over-temperature protection is added to 20 ℃ ~ 30 ℃.

When the temperature in the test chamber rises to the set point of over-temperature protection, the power supply of the heater stops, the over-temperature warning light is on but the fan is still running, if it runs for a long time and is unattended, please make sure to check the over-temperature protection Is the device properly set? The setting of the wet bulb over-temperature protector is 120 ° C.

6. Cleaning and maintenance of the inside and outside of the cabinet

The machine should remove internal impurities before operation.

The power distribution room should be cleaned regularly. When cleaning, use a vacuum cleaner to remove the indoor dust.

The outside of the cabinet must also be cleaned more than once a year. When cleaning, wipe with soapy water first.
