Constant temperature and humidity test chamber how to use and maintain correctly

Date: Apr 19,2023 Views: 150

This article explains how to skillfully use the constant temperature and humidity test chamber. For any electrical appliance or equipment, it is necessary to master its precautions before use. After the equipment is purchased, the first thing to do is not to put it into use immediately. Instead, the first thing to do is to learn by referring to the relevant product introduction and precautions in the manual, understand the safety instructions such as electricity consumption, disassembly and assembly, and then use it. This requires customers to have a certain degree of understanding and familiarity with the equipment before using the test chamber. So what problems should be paid attention to in the use of this equipment?

 

1, the constant temperature and humidity test chamber in the work, please try not to open the door of the test chamber, open at high temperature may cause burns to the operator, open at low temperature may cause frostbite to the staff, and may cause the evaporator icing, affecting the refrigeration effect. If you must open, please do some protective work.

 

2, the equipment before starting to check whether the power supply is stable, wiring must be correct, must be grounded. Non-grounding may cause electric shock, misoperation, abnormal display, or large error in measurement.

 

3. In order to avoid machine failure in the constant temperature and humidity test chamber, please provide power supply within the rated voltage range; Check terminal screws and fixers regularly. Do not use them when they are loose.

 

During the operation of the instrument in the constant temperature and humidity test chamber, the power input terminal cover must be installed on the terminal board to prevent electric shock. Use a dry cloth to wipe the instrument. Do not use alcohol, gasoline or other organic solvents. Do not splash water on the instrument.

 

Constant temperature and humidity chamber is also called "constant temperature and humidity test chamber", belong to the high and low temperature series, is the necessary test equipment in aviation, scientific research and other fields, used to test and determine the parameters and performance of electrical, electronic and other products and materials for high temperature, low temperature, alternating humidity and heat degree or constant test temperature environment changes, what problems should we pay attention to when doing measurement?

 

First, when reading the hygrometer value of the constant temperature and humidity chamber, the time before and after should be as short as possible, it is best to read at the same time at three points, and pay attention to the reader's eye unity. The same thermometer reads the wet bulb temperature first.

 

2. The temperature and humidity curve automatically recorded by the hygrograph configured inside the equipment shall fluctuate in accordance with the data measured by the hygrometer. Otherwise, it is considered that the record is inaccurate. Truthfully, the temperature and humidity of the constant temperature and humidity test chamber meet the standard requirements, and the recorded temperature and relative humidity must be within the allowable limits at all times.

 

3. When reading the value of the hygrometer, objects with different temperatures from the equipment, such as human hands and faces, should be kept away from sensitive mercury spheres as far as possible.

 

The inner liner of the constant temperature and humidity chamber is made of imported SUS304 stainless steel plate. The spray is made of ultrasonic humidification, high-power compressor, double-layer vacuum glass door, temperature and humidity digital display intelligent instrument can be installed with a micro printer. It is an excellent equipment for testing the parameters and performance of the product in the laboratory and quality inspection center.
