The use of constant temperature and humidity box:
The constant temperature and humidity chamber can accurately simulate complex natural environment such as low temperature, high temperature, high temperature and high humidity, low temperature and low humidity. The laboratory is generally used for plant culture and breeding experiments; bacteria, microbial culture, fermentation, various constant temperature tests, environmental tests. , water body analysis, BOD measurement, microbial culture material denaturation test and storage of media, serum, drugs and the like.
The constant temperature and humidity chamber is widely used in research and application fields such as medical and health, electronics, semiconductor, medicine, chemical, cosmetics, coatings, bio-pharmaceutical, agricultural research, and environmental protection.
How to maintain the constant temperature and humidity box:
1. The heat dissipation (condenser) of the refrigeration unit should be regularly maintained and kept clean. The dusty paste condenser will cause the compressor high voltage switch to trip and cause false alarm. The condenser should be regularly maintained monthly. Use the vacuum cleaner to remove the dust attached to the condenser heat sink net or use the hard brush after booting. Or use a high pressure nozzle to blow clean dust.
2. When opening or closing the test object from the furnace, the glue edge of the item door shall not be touched to prevent the rubber edge from being damaged and shortening the life.
3. The temperature around the fuselage of the constant temperature and humidity chamber should be kept clean at all times to avoid accidents and reduce performance caused by a large amount of dust inhaling into the unit.
4. The freezing system is the core of the machine. Please check all the copper pipes for leaks in one year. The speaker joints and welding joints, if there is any oil spill, please inform the company or directly deal with it.
5. The large current contact of the switchboard, the power distribution room should be cleaned and repaired at least once a year. The looseness of the contact will make the whole equipment in dangerous working condition, and the components will be burned out, but the fire, alarm and personal injury are very dangerous. When cleaning Please use a vacuum cleaner to remove indoor dust.
6. The humidifier and the water rust are often cleaned to avoid scale and affect the evaporation of the steam. Generally, the test is cleaned once, and the scale is removed in time to facilitate the life of the humidifying tube. To ensure smooth water flow, use a copper brush to wash the water. clean.
7. Wet cloth of dry and wet balls is often inspected. When the surface of the test cloth is not clean or hardened, or after the temperature is controlled above 85 °C, continue to control before temperature and humidity. If it is checked, please change it if it is not water-absorbent. It is related to the accuracy of moisture measurement. The test cloth is usually replaced once in March. When replacing, use the cleaning cloth to wipe the temperature measuring body. When replacing the new test cloth, wash the hand and then clean the sink. .
8. Check and adjust the wet bulb water level: The water level of the water trap should not be too high. If the water overflows the water trap or the water is too low, the wet bulb test cloth will not absorb water properly, which will affect the accuracy of the wet bulb. The water level is approximately six minutes full. Adjust the water level of the water tank to adjust the height of the water tank [adjust the screws on both sides]
