Select constant temperature and humidity test chamber according to control method

The constant temperature and humidity test chamber has two test methods: constant damp heat test and alternating damp heat test. The ordinary constant temperature and humidity test chamber generally refers to a constant damp heat test chamber, and the control mode thereof is a constant humidity and humidity test chamber having a constant damp heat test and an alternating damp heat test. The ordinary constant temperature and humidity test chamber generally refers to a constant damp heat test chamber, and the control mode is: setting a target temperature and humidity point, and the test box has the ability to automatically adjust the temperature to the target temperature and humidity point. The high and low temperature alternating heat and humidity test chamber has a program for setting one or more stages of high and low temperature changes and circulation, and the test box has the ability to complete the test process according to the preset curve, and can control the temperature rise and fall in the range of the heating and cooling rate capability. The rate, that is, the temperature rise and temperature drop rate can be controlled according to the slope of the set curve. Similarly, the high and low temperature alternating heat and humidity test chamber also has a preset temperature and humidity curve, and the ability to control according to presets. Of course, the alternating test chambers all have the function of a constant test chamber, but the manufacturing cost of the alternating test chamber is higher, because the alternating test chamber needs to be equipped with a curve automatic recording device, a program control device, and the test chamber must be solved in the working chamber. When the temperature is high, the refrigerator is turned on. Therefore, the price of the alternating heat and humidity test chamber is generally 20% higher than the price of the constant damp heat test chamber. Therefore, we should be realistic and take the test method as the starting point, choose a constant test box or an alternating test chamber.

It is a white inorganic pigment with non-toxic, best opacity, best whiteness and brightness, and is considered to be the best white pigment in the world today. Titanium white has strong adhesion, is not easy to change chemically, and is always white. Widely used in coatings, plastics, papermaking, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point, and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc.
