■it is fit for the test which has the Larger product or more product testing amount
■the stainless steel plate and salinized are the main materials in the standard modular design.
■it can be designed according to the required size of clients and match the migration due to plant expansion.
■ there are safety latch of Indoor openable door and electric leakage circuit breaker protection device (person)
■ there is the synchronized safety control of the test power of and safety protection device of tested products (object)
■ automatic water supply device for RO reverse osmosis water filter for humidity water
■ Inner box of SUS # 304 and outside box of colored steel plate
■ the heat load automatic servo adjusts refrigerant flow, and the heat load more than 3 times of that of the constant temperature and humidity chamber can be withstood. The low-humidity of 20% RH is effectively controlled.
■ The special design and production can be made according to user requirements of the temperature, humidity, load, heat, wind speed and other requirements.
■ It can be operated with the computer by the RS-232 and RS-486 interface

Product advantages：
1. The controller operation uses the fuzzy algorithm, the latest technology control and proper adjustment of refrigeration to make the best results; 7 "TFT true color LCD touch screen is larger than the other screens.
2.The controller interface of humanization design has more convenient operation and more reliable operation.
3. The refrigeration control system adopts cooling demand algorithm to reasonably and effectively use cooling capacity and effectively reduce the mutual consumption of heat and cold so as to achieve control stability and energy saving
4.The coupling PID adopted by the temperature and humidity control can effectively prevent the sudden runaway of the controlled humidity value, which not only makes constant temperature and humidity but also achieves well the function of alternating temperature and humidity .
5.The refrigeration system adopts imported compressor which has the lower noise and better performance.
6. The sampling calculation for a second can ensure the real-time curve sampling and historical data storage for 110 days. The sampling rate can be arbitrarily set from 3 seconds to an hour.
7. Extra long constant time of 99999 hours
8. The program segment setting time of 540 hours and 59 minutes
9. There is the USB interface to connect computer and corporate LAN.
