Constant temperature and humidity test chamber overall structure: the cooling system in the lower part of the box, the control system in the upper part of the constant temperature and humidity test chamber. The test room at one end of the air flue interlayer, the distribution of heaters, refrigeration evaporator, fan and other devices. On the left of Constant temperature and humidity test chamber has Ф50 cable hole, the door is a single door stainless steel embedded door handle. Adopt double-resistant high-temperature anti-aging silicone rubber seal, can effectively guarantee the loss of temperature in the chamber.
Constant temperature and humidity test chamber door with observation window, anti-frost device ,can switch control of lights. The observation window adopts multi-layer hollow tempered glass, and the inside bonding film conductive film heats defrost. Lighting is imported Philips lamp, you can effectively observe all aspects of the work room of the test sample changes.
The volume of the constant temperature and humidity test chamber: when put the test product into the test chamber for testing, in order to ensure that the atmosphere around the product to be tested to meet the test requirements of the environmental conditions, climate chamber work space size and the size of the tested product size Should follow the following provisions:
1.The volume (W × D × H) of the tested product shall not exceed (20-35) (20 is recommended) for the effective working space of the test chamber. It is recommended to use no more than 30 for products that are heating in the test.
2. The ratio of the wind-breaking area of the tested product to the total working area of the test chamber on the section is not more than 35-50. (35 is recommended).
3. The surface of the tested product should be kept at least 100-150mm away from the wall of the chamber(150mm is recommended).
Constant temperature and humidity test chamber in the electronics industry, defense technology, chemical industry, machinery manufacturing, aerospace and other fields have been widely used, Dongguan Right Testing Machine Co.,Ltd production of constant temperature and humidity test chamber using a unique triple seal system to ensure accurate and uniform and stable temperature and humidity values. Highly flexible water source. Meet a variety of standards. Easy to operate, safe and reliable. Access to the vast number of users of praise.
Then how to maintenance and cleaning RIGHT constant temperature and humidity test chamber in the daily work?
1.Constant temperature and humidity test chamber (Simulate environmental test chamber) inside and outside the cleaning and maintenance 1) Before the operation should clean and remove impurities in constant temperature and humidity chamber internal room . 2) The distribution room a year cleaning more than one time at least, when cleaning ,can use a vacuum cleaner clean indoor dust is enough . 3) The outside of the box must be cleaned more than one time per year, when cleaning with soap and water can be wiped.
2.Constant temperature and humidity testing chamber humidifier inspection and maintenance. Water in the humidifier should be replaced once a month to ensure clean water, humidified water dish should be cleaned once a month to ensure smooth water flow.
3.Constant temperature and humidity box condenser dust removal. Clean the condenser should be regularly monthly maintenance, using the vacuum cleaners remove dust attached on condenser heating net or use high-pressure air spray dust.
4.Constant temperature and humidity test machine wet bulb test cloth replacement, When the test cloth surface is not clean or hardened, or done after the temperature control, continue to do temperature and humidity control must be replaced cloth before the test. Replace the test cloth about 3 months ,when replacement,should use cleaning cloth clean thermometer (sensor), replace the new test cloth should be cleaned.
5.Check the constant temperature and humidity test equipment wet bulb water level and adjust the water cup level can not be too high, so that the water overflow tube or too low the wet bulb test cloth absorbent is not normal, affect the accuracy of the wet ball, water level is about 60% of cup is enough. The water cup level adjustment, can adjust the water cup height.
