AtmoExplorer Temperature and Humidity Chamber | This is a newly developed product by the sister company ChiuVention.

Q: How to choose the size of a temperature humidity chamber?

A: Generally the size of temperature humidity chamber is decided according to the size of the test product, and the size of the test studio should be greater than or equal to 3 times the size of the test product to ensure that the air around the samples in the testing process can circulate sufficiently to achieve a uniform temperature and humidity environment.

 

Q: What is the application range of Temp and Humidity Chamber?

A: Laboratory use

Generally used in for plant culture, breeding test; bacteria, microbial culture, used as breeding, fermentation, microbial culture, a variety of constant temperature test, environmental testing, material denaturation test and culture medium, serum, drugs and other items such as storage.

It can be widely used in drug, textile, food processing and other aseptic test, widely used in medical and health care, biopharmaceutical, agricultural research, environmental protection and other research applications.

Suitable for electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metal, food, chemical, building materials, medical, aerospace and other products for quality testing.

4 High and low temperature alternating humidity test chamber

Combining high and low temperature and humidity changes, simulating extreme environmental conditions, suitable for material weathering test.

Applicable to aerospace products, information and electronic instruments and meters, materials, electricians, electronic products, various electronic components.

 

Q: During the humidity and heat testing process, we observed a significant discrepancy between the actual humidity and the target humidity, with the actual value being much lower. What steps can we take to address this issue?

A: Firstly, check the water supply of the humidification system, whether there is a certain amount of water in the water supply system.

Secondly, check whether the humidification boiler water level control is normal. If all of the above are normal.

At last, we have to check the electrical control system, which should be overhauled by professional maintenance personnel.

 

Q: How to fix when low temperatures fail to meet targets and cool down very slowly?

A: If the temperature drops very slowly, you need to check the following points.

Check whether the temp humidity chamber has been dried before doing the low temperature test, the chamber needs to be dried before the test, and then put the test sample test;

Check whether the test samples in the working chamber are placed too much, resulting in the air in the working chamber can not be fully circulated;

Check whether the refrigeration system is faulty.If the temperature reaches a certain value after a tendency to go back up

First check whether the use of constant temperature and humidity test chamber environment, equipment placed in the ambient temperature and placed in the location (after the box and the distance from the wall) to meet the requirements.

 

Q: In the high temperature test, the temperature change cannot reach the value of the test temperature, how to solve it?

A: If the temperature rises slowly, you need to check the wind circulation system, whether the wind circulation of the regulating flap is normally open.

If the temperature rises very quickly, check whether the motor of the wind cycle is running normally. If the temperature overshoots great then you need to adjust the PID setup parameters. If the temperature rises directly, over-temperature protection, then the controller failure, must replace the control instrument.

 

Q: How can we address the issue of temperature control when there is abnormal pressure?

A: First of all, you need to check the placement of the temperature and humidity controlled cabinets, whether it is more than 30cm away from the wall position, because poor heat dissipation will cause the high pressure side of the compressor is too high, so if it is caused by improper placement, you need to correctly adjust the position in a timely manner;

Secondly, check whether the temperature and humidity chamber is surrounded by sealed space, if surrounded by closed space, it will cause the environment to produce temperature rise, will also cause the high pressure side of the compressor is too high, so please keep the ventilation around;

If it is not the above faults, you need to ask a professional for overhaul.

 

Q: How to deal with the high-pressure alarm of the temperature and humidity test chamber?

A: 1 Check whether the site ambient temperature is too high. If the site temperature is above 30 ℃, open doors and windows or exhaust system ventilation, open air conditioning to reduce the ambient temperature;

2 Ensure that the distance between the environmental box and other objects (or walls) is greater than 60 cm for better heat dissipation. (If the air is exhausted upwards, it is necessary to install an exhaust pipe to direct the hot air outdoors.)

3 Check whether the compressor is at normal pressure value. (If the pressure is too high, discharge part of the refrigerant to make it reach the normal pressure value.)

4 Check whether the condenser is dirty and blocked. If the condenser is dirty and blocked, it will easily absorb dust and impurities, which will affect the ventilation and heat dissipation, and the condenser should be cleaned up.

5 Check whether the condensing fan is running normally. If the condensing fan is damaged and affects the wind circulation, the condensing fan should be replaced.
