Dongguan Bell explains the difference between constant temperature and humidity box and high and low temperature box 1. Only do high temperature and low temperature without humidity, directly called high and low temperature test chamber. Also called "high and low temperature alternating test chamber"; 2. To do high temperature and low temperature, at the same time to be able to do humidity, cycle, we call high and low temperature wet heat alternating test chamber, constant temperature and humidity box; The general constant temperature and humidity chamber can do the "wet heat alternating test" but depending on the alternating test conditions you have made, if you want to buy equipment, you should inform the supplier of your requirements before you buy the equipment. So that the equipment can be designed and debugged according to your requirements. Of course, depending on the conditions you mention, the price of the manufacturer is different. Single literal interpretation Constant temperature and humidity box: Generally speaking, the temperature is 15 degrees to 85 degrees, and the humidity can be 20% to 98% RH. Of course, lower humidity can be made according to requirements. We call it low temperature and low humidity test chamber. High and low temperature wet heat alternating test chamber: the general temperature will be -20 degrees or lower, and the humidity can be done (only 15 to 85 degrees). The wet-heat alternation test is mainly: during a certain period of time, the temperature remains constant and the humidity is tested according to the rate of change you set, or vice versa. There are also tests that require temperature and humidity to vary simultaneously at a set rate. The general constant temperature and humidity test is to control the humidity after the temperature arrives first (in a word: alternating means controlling temperature and humidity at the same time). Insect net greenhouse also known as plant and vegetables greenhouse net. Used for prevent the insect fly into the greenhouse during the plant growing, and cover the plants. Key off the approaches that the pests (adult insect) breeding. Effective control of the spread of all kinds of harmful pests spread, such as Cabbage caterpillar, diamondback moth, aphids, flea beetles, Sweet agnates, American leaf miner, literal etc and prevent the harmful of virus spread. Significantly reduced the use of chemical pesticides, so that the planting vegetables good-quality and health.
