How to choose the right environmental control chamber for your needs?
1. Determine the test requirements
Before choosing the test chamber, we must define their testing needs. You can determine the required environmental control chamber’s performance and specs. This depends on the test items, conditions, time, and other factors.
2. Temperature range and stability
Temperature range and stability are important indicators for selecting an environmental control chamber. Select the environmental control chamber’s temperature range. Do this per the test requirements. At the same time, we must monitor the test chamber’s temperature range. For some high-precision tests, the temperature stability must be high.
3. Humidity control capability
Some tests need to control both temperature and humidity. So, consider the humidity control when choosing an environmental control chamber. The test requires checking the humidity range. Then, select the right humidity control for the environmental control chamber.
4. Size and capacity
Determine the required size and capacity of the test chamber based on the size and number of items to be tested. Check that the test chamber can fit and test the items.
5. Control system and interface
Also, consider the control system and interface of the test chamber. Modern environmental control chamber have intelligent control systems and friendly interfaces. They help users operate and monitor the tests. So, when buying an environmental control chamber, check its control system. Also, test the interface for ease of use.
6. Safety and reliability
When choosing an environmental control chamber, safety and reliability are also important. The test chamber must meet safety standards. It should have overload, overheating, short-circuit, and other protections. We must also consider the test chamber’s stability and reliability. It must run for a long time without failing during tests.
7. After-sales service and maintenance
Also, consider the supplier’s support after the sale when picking an environmental control chamber. Choose an environmental control chamber that allows for timely maintenance and support. This will protect the equipment’s normal operation and use.
Temperature and humidity controlled cabinets how to choose the working environment?
(1) The workshop should be kept clean and dry. The room temperature should be within the range of 10℃～30℃ and the relative humidity should be <80﹪RH.
(2) The instrument should be placed on a horizontal, smooth, flame-retardant ground with certain friction.
(3) The working area should be set in a place with less vibration interference.
(4) The instrument should be kept away from objects and equipments which are magnetic or can generate magnetic field.
(5) The instrument shall not be used in areas with explosive hazards.
(6) The instrument shall not be used for a long time in a high humidity or dusty environment.
Are you doing the daily maintenance of the temperature and humidity controlled cabinets correctly?
Maintenance of the temperature and humidity controlled cabinets is very basic. Check whether the screws, parts, connecting lines, and boards are loose, corroded, missing, not solid, dented, or cracked. Also, check if gaskets, plugs, and seals are aging. Deal with any issues in a timely manner.
The compressor plays a very important role in the instrument, and expensive. Therefore, it is also important to do a good job of routine maintenance of the compressor. The compressor requires a stable voltage; otherwise, it is easy to cause damage. So, install a voltage stabilizer on the test box; do not switch the compressor on and off frequently. Each switch interval should be more than 15 minutes.
If the equipment motor or turntable reducer is not running well or making a murmuring sound, you should remove any debris and lubricate it with oil.
Regularly check whether there is leakage or stain deposition in the pump, pipeline and drainage box in the circulatory system, and carry out maintenance and cleaning.
If you don’t use the temperature and humidity controlled cabinets for a long time, turn off the power. Clean and dry the box. Put it in a dry, ventilated place with no direct sunlight. Don’t cover the equipment with plastic to prevent dust. Dust can cause parts to corrode. Even if you’re not using it, it’s best to turn it on once a month for about an hour to protect the compressor.
To prevent parts from rusting, regularly wipe them with oil. Also, add equipment on time and avoid using tap water with impurities. Instead, use pure water, distilled water, and the like.
