The constant temperature and humidity test box, also called environmental test box, is also known as destructive data for testing product data. It is used to test the product's heat, cold, dry, and moisture resistance. For electronics, components, electrical appliances, mobile phones, communications, instrumentation, vehicles, plastic products, metals, food, automobiles, chemicals, building materials, medical, aerospace and other products used for testing quality.
  When the humidity and humidity test chamber is used in a constant temperature and humidity test chamber, if the humidity does not meet the specified requirements, which problem arises?
Check the reason why the gauze on the wet ball sensor dries. If it is necessary to check the water tank of the wet ball sensor for lack of water. Whether the water level in the water tank is normal and whether the water level controller is working properly. If you do not understand the instructions, it may be that the wet bulb gauze is used for a long time, or the water supply quality is not pure. This will make the gauze unable to detect the humidity and make the gauze unable to absorb it. Moisture, as long as the replacement or cleaning of gauze can eliminate the above phenomenon.
The difference between the actual humidity and the target humidity is too large, the value is much lower, the humidification of the constant temperature and humidity test box does not work, the water supply system for detecting the humidification, whether there is water in the water supply system, and whether the water level control of the humidification boiler is normal, if all of the above is normal, then It is necessary to check the electrical control system, which requires professional maintenance personnel to perform maintenance. If all of the above is normal, then check the electrical control system, which requires professional maintenance personnel to perform the repair. The structure of the constant temperature and humidity test box is roughly the outer box cold-rolled steel plate paint or stainless steel SUS 304# processing; the inner box is SUS 304# 8K mirror stainless steel plate, the middle insulation layer is polyurethane foam (make sure the humidity drop To the lowest), light and durable, anti-corrosion, box door is closed with magnetic strips, with beautiful appearance, high temperature control precision series.
The constant temperature and humidity box is equipped with a closed refrigeration unit, which is stable in operation and low in noise. The stainless steel fin type heating pipe heats the air and is heated to form rust-proof and anti-corrosion. It also has a French (TaiKong) fully-enclosed compressor set, +20~150°C (A) type non-freezing system and Germany (Boozer) semi-hermetic compressor.
Control instrument Kw-890 adopts Chinese-English LCD (LED backlight) 7-inch color VGA (800*480) touch screen human-computer interface computer control, standard USB and RS-232 communication interface, USB data can be imported and exported verification data, Download curves directly for data storage. Support LAN (network port) GPRS (mobile phone) and other methods of communication, convenient remote monitoring, data acquisition (optional).
