Parameters of domestic constant temperature and humidity test chamber

Operation and maintenance of high-quality constant temperature and humidity test chamber

Operation steps:

　　Place the sample：

Place the sample to be tested on the sample rack inside the constant temperature and humidity test chamber.

The placement of samples should be evenly distributed to avoid accumulation and obstruction, ensuring that the samples can be fully exposed to a constant temperature and humidity environment.

　　Set parameters：

According to the experimental requirements, set the temperature and humidity parameters of the constant temperature and humidity test chamber.

The temperature range can usually be adjusted between -70 ℃ and 150 ℃, and the humidity range is between 10% RH and 98% RH.

Ensure that the parameter values are accurate, reasonable, and meet the experimental requirements.

　　Start the experiment：

After setting the parameters, start the constant temperature and humidity test chamber and begin the experiment.

During the experiment, closely observe the operation of the equipment and changes in the status of the sample.

If there is any abnormal situation, the machine should be stopped in a timely manner and the fault should be eliminated.

　　The experiment is over.：

After the experiment is completed, first turn off the heating and humidification functions of the constant temperature and humidity test chamber, and let the equipment cool and dry naturally.

Open the door of the constant temperature and humidity test chamber and take out the experimental sample.

Check if the ventilation holes and heat sinks inside the equipment are blocked, and clean them promptly if there are any blockages.

Maintenance precautions:

　　Humidification work：

Humidification work must be done with water, especially distilled water or ultrapure water, to maintain humidity control and prevent secondary contamination of the sample.

After the humidification work is completed, the studio of the constant temperature and humidity test chamber should be wiped dry to ensure the correctness of the humidity requirements for the next operation.

　　Power supply and grounding：

The constant temperature and humidity test chamber should use an independent power socket and ensure that the socket is well grounded.

The equipment casing must be grounded and neutral or neutral wires cannot be used as grounding wires.

　　routine inspection：

Regularly inspect circuit breakers and over temperature protectors to ensure the safety of test products and operators.

The installation position of wet bulb gauze must be accurate to measure the correct relative humidity.

　　Cleaning and Maintenance：

Maintain the cleanliness of the constant temperature and humidity test chamber. Do not wipe the door glass with reactive chemical solutions, but use a soft cotton cloth.

After each experiment, the inside and outside of the machine should be cleaned properly.

　　special maintenance：

When operating at low temperature in a constant temperature and humidity test chamber, it is recommended to dry at 60 ℃ for about 30 minutes before opening the chamber door to avoid affecting the later test or causing the evaporator to freeze.

If the rubber plug of the vent valve has difficulty rotating, apply an appropriate amount of lubricating grease inside.

Following the above operation steps and maintenance guidelines can ensure the normal operation and prolong the service life of the constant temperature and humidity test chamber, while ensuring the accuracy and reliability of the experimental results.

The constant temperature and humidity test chamber is a testing equipment widely used in multiple industries, such as electronics, automotive, aerospace, and medical fields, to evaluate the performance and reliability of materials and products under various environmental conditions. The following is a technical analysis of a high-quality constant temperature and humidity test chamber:

Basic working principle

The basic working principle of a constant temperature and humidity test chamber is to use temperature and humidity sensors to monitor the environmental conditions inside the chamber, and adjust the temperature and humidity of the test chamber through a control system to achieve the desired testing environment.

Core components

　　boxHigh quality test chambers are typically made of high-strength, corrosion-resistant materials to ensure structural stability and durability.

　　Temperature control moduleMainly composed of a heater, a refrigerator, and a fan. The heater is used for heating, the refrigerator is used for cooling, and the fan ensures a uniform distribution of temperature inside the test chamber.

　　Humidity control moduleMainly composed of a humidifier and a dehumidifier. Humidifiers are used to increase humidity, while dehumidifiers are used to decrease humidity.
