Maintenance and inspection of constant temperature and humidity incubator

1. Replacement of wet bulb test cloth

When the surface of the test cloth is not clean or hardened, or after the temperature control is completed, the test cloth must be replaced before continuing the temperature and humidity bulb control.

The test cloth should be replaced about once every three months. When replacing, the temperature measuring body (Sen-sor) should be wiped with a clean cloth, and should be cleaned before replacing the new test cloth.

2. Inspection and adjustment of wet bulb water level

The water level of the water tank should not be too high, so that the water overflows the water tank or is too low, so that the wet bulb test cloth absorbs water abnormally, which affects the accuracy of the wet bulb? The water level should be kept about six points full.

The adjustment of the water level of the water tank can adjust the height of the water tank (adjust the screws on both sides).

3. Removal of condenser dust

The condenser should be maintained regularly and monthly. Use a vacuum cleaner to absorb the dust attached to the cooling mesh of the condenser or use high-pressure air to spray the dust.

4. Check the over temperature protector

When the machine is running, add 20℃~30℃ to the set maximum value of over temperature protection. [Industrial Electrical Network-cnelc]r>  When the temperature in the test chamber rises to the set point of the over-temperature protection, the power supply of the heater will stop, the OVERHEAT over-temperature warning light will be on, but the fan will still run. Please be sure to check the over-temperature protector before operation. Is it set properly? (The setting of the wet-bulb over-temperature protector is 120℃).

5. Cleaning and maintenance inside and outside the box

The internal impurities (objects) should be removed before the machine is operated. The power distribution room should be cleaned at least once a year, and a vacuum cleaner can be used to remove the indoor dust during cleaning. The outside of the box should also be cleaned more than once a year. Wipe it with soapy water first.

6. Inspection and maintenance of the humidifier

The water stored in the humidifier should be replaced once a month to ensure the water quality is clean, and the humidifying water pan should be cleaned once a month to ensure smooth water flow.
