Constant temperature and constant humidity box

The 1. air duct structure adopts the concept of annular air flow design, forced convection to simulate the principle of air circulation. The specially designed high power air circulation wind blade can produce higher air velocity. It ensures the high uniform stability of the temperature and humidity of the inner air.
2. electronic humidity sensor is used for absolute precision humidity measurement, electronic control humidification and dehumidification system. The ROTRONIC electronic humidity sensor can ensure reliable humidity detection even if the sample is changed frequently, without the need to maintain the sensor.
3. the innovative refrigeration system adopts international brand refrigeration compressor and German EBM condenser fan, environment-friendly fluorine free 134a refrigerant, environmental protection, energy saving, precision and efficiency.
4. the test holes of the 45mm diameter produced by the special mold are set around the body of the test hole, which is convenient for the user to monitor. The internal silica gel soft plug is configured to ensure that the temperature and humidity in the box will not be affected in the experiment.
5. easy to maintain, easy to maintain, clean condenser, improve refrigeration performance and save energy.
The special interface of the 6.RS232 interface PC machine, a special software disc (suitable for simplified Chinese WINDOWS2000 or the simplified Chinese WINDOWS XP operating system), the test program is programmed and monitored and saved through the special software of PC machine. The test data is directly displayed and printed by the special software of the PC machine.
7. the water in the tank is convenient to maintain the inner liner. The structure is easy to discharge in the high school side, and the box is clean and sanitary.
Application scope: it is mainly used for long-term preservation test of drug, food quality test, resin material, automobile parts, environmental test of electrical and electronic products, water body analysis, BOD determination, bacterial strain, microorganism culture, vaccine preservation and other special equipment.
The product box adopts CNC machine tool, laser processing technology, and the outer box adopts high quality cold rolling plate. It has very strong rust resistance, and the inner liner uses SUS304 stainless steel plate.
The bottom casters are imported from Japan, the direction is free and adjustable, and can be locked. The outer box is processed by DuPont powder spray.
The 45mm diameter measuring hole is set up on the left and right sides of the box, which is convenient for users to test.
Enclosure heat insulation material adopts Germany Bayer fluorine free polyurethane integral foaming technology, which greatly improves the thermal insulation performance, thereby greatly reducing energy consumption. Compared with similar products, it can save more than 30%, and the overall strength of the box is good.
Reasonable air duct structure adopts balanced control mode. The imported special motor and fan blade make the temperature and humidity distribution more uniform, which greatly improves the accuracy of the box and the uniformity of temperature and humidity.
The water frosted in the box can be condensed and evaporated through the compressor, and it will not flow into the ground.
Adopt international brand refrigeration compressor and German EBM condensing fan. Environmentally friendly fluorine free 134a refrigerant is in line with the trend of the world.
Program control temperature and humidity control, fuzzy microcomputer PID control. Temperature priority, time priority, users can choose. It has programmable intelligent program mode operation function, the control part adopts high brightness and super large liquid crystal display, and uses fuzzy PID control mode, it is more humanized
The temperature sensor PT100 selects Honeywell products. The humidity sensor is selected from the original Swiss rosenk capacitance sensor.
It has over temperature protection function, leakage protection, door opening alarm, power failure alarm, sensor alarm and so on. It can greatly improve the security of the use. At the same time, it has automatic start, automatic stop, timing operation, clock display, caller self recovery function.
With automatic defrosting and manual defrosting two functions for the user to choose, more suitable for the long-term test, relieving the users in the use of severe frosting and cause temperature and humidity drift.
