THW series programmable (high and low temperature) humidity and heat testing machine
Constant temperature and humidity testing machine / THW series programmable (high and low temperature) damp heat testing machine
Usage description:
This series of products are widely used in aviation, aerospace, information, electronics, instruments, meters and other industries, used for accelerated damp heat test, alternating damp heat test and constant damp heat test of electrical and electronic products, materials, parts, equipment, etc., to inspect them Various performance indicators to evaluate the behavior and performance of the sample under given environmental conditions.
Features:
- The box body is processed and formed by CNC machine tools, and the appearance is beautiful and generous.
- The large observation window is equipped with illuminators to keep the inside of the box bright, and uses the built-in tempered glass in the heating body to clearly observe the situation in the box at any time.
- Double-layer high-temperature-resistant high-tensile sealing strips are used between the door and the box to ensure the sealing of the test area.
- The left side of the box is equipped with a test hole with a diameter of 50mm, which can be used for external test power lines or signal lines. (The aperture or the number of holes must be increased when ordering).
- Ingenious air duct structure, low noise and good temperature uniformity.
- The humidification water source can be recycled, and there is automatic protection for water shortage.
- The official road of the humidification system is separated from the control circuit board, which can avoid failure due to water leakage in the humidification official road and improve safety.
- The piping circuit system of the waterway system adopts door opening, which is convenient for maintenance and overhaul.
- Imported refrigeration units and key accessories are imported international famous brands to improve operation reliability.
- THW series adopt imported temperature and humidity controller, temperature and humidity are directly displayed.
- THw series adopts LCD LCD button type program control, simple screen operation, highly user-friendly operation, easy program editing, and key input options. Chinese interface, with multiple sets of multi-segment programs, the maximum value of each period of time is 99 hours and 59 minutes. The connection procedure is not restricted. The system is fully automated and easy to operate, effectively solving the problem of operator learning and training.
- With the function of automatic calculation, the temperature and humidity changing conditions can be controlled randomly, making the temperature and humidity control more accurate and stable.
- Adopting multi-wing blower to provide powerful air circulation to avoid any dead angles and make the temperature and humidity distribution in the test area even.
- The wind path is designed to circulate the wind and return the wind, and the wind pressure and speed are in line with the test standards, and the temperature and humidity at the moment of opening the door can stabilize quickly.
- Completely independent heating, cooling, and humidifying systems can improve efficiency, reduce test costs, increase lifespan, and reduce failure rates.
- Thw series all Chinese display studio over temperature, compressor overload, over pressure, water shortage, fan overload, error and other fault points, which is convenient for maintenance. There is compressor delay protection function.
- Optional remote monitoring computer and software, the upper computer implements a redundant design, can be connected to a PC computer, and realizes paperless recording. .The host machine does not affect the system control.
