It integrates the company's many years of successful experience in box design and adopts humanized design concepts. Starting from the actual needs of customers, it meets customer requirements in details and provides high-quality products.
Features
1. Humanized design: Fluorine-free design supports healthy life; Dry and wet ball or electric kiln type multi-functional multi-stage programmable temperature and Humidity controller, fuzzy PID controller, accurate fluctuation of temperature and humidity control; Imported temperature and Humidity controller has long life, High Accuracy CFL20 words × 6 lines LCD display, keyboard input is easy to operate; There is a 25mm or 50mm diameter test hole on the left side of the box, which is convenient for experimental operation and Measuring temperature; The built-in sink can be pulled out and added with water, which is convenient to use.
2. Quality assurance: brand Compressor and circulating fan make the temperature distribution uniform; environmentally friendly refrigerant (R134a) has high efficiency, low energy consumption, and promotes energy saving; unique air duct circulation system ensures uniform working room temperature Humidity; imported 304 mirror stainless steel liner, four corners and a half arc excessive, shelf bracket free loading and unloading, easy to clean in the box; multi-stage programmable control simplifies the complex test process and realizes automatic control and operation.
3. Safety functions: independent temperature limit alarm system, automatic interruption of operation and sound and light alarm if the temperature exceeds the limit; high temperature, low temperature and over-temperature alarm; Compressor overheating, overcurrent, overload protection, fan overheating protection, water shortage protection, etc.
4. Convenient data processing (optional): can be connected to a printer or 485 Communication interface, with USB data transfer interface (SD disk), with a computer to display and print Humidity and Time Linear dispersion, for inspection process data storage and playback to provide assurance.
5. Programmable Touchscreen Controller (BPHJS series standard): Color LCD touch control screen, menu-type Operating interface intuitive and easy to operate; Chinese and English Operating interface optional, screen display real-time temperature Humidity Run Linear dispersion; 100 sets of 1000 steps 999 cycles can be preset, and the maximum time setting is 99 hours and 59 minutes; screen lock function avoids human touch to change data or stop; P.I.D automatic calculation function corrects temperature Humidity changes, making the control more accurate and stable; RS-232 or RS-485 Communication interface, can design programs, monitor the test process and execute the switch machine on the computer; professional control software can monitor and control 9 devices at the same time; computer real-time analysis and storage of data, forming Excel or Word documents for easy printing.
Principle
The test chamber adopts dry and wet bulb type or electric kiln type multi-functional multi-stage programmable temperature and Humidity controller, combined with fuzzy PID controller, to achieve precise temperature control and humidity control with small fluctuation. Through brand Compressor and circulating fan, with environmentally friendly refrigerant (R134a) and unique air duct circulation system, ensure uniform distribution of working room temperature Humidity. Built-in Safety protection system such as independent temperature limit alarm and a variety of overheating and overload protection ensures the safe operation of the experiment.
Applications
Damping heat testing chamber is widely used in electronics, automotive, aerospace, materials, chemical, pharmaceutical and other industries. Reliability testing, environmental adaptability assessment, quality control and other experimental fields.
Standards
The product meets the relevant environmental testing equipment standards, the specific standards are not mentioned in the information.
Steps
1. Power supply voltage AC380V 50Hz.
2. Set the Temperature and Humidity parameters through the color programmable Touchscreen controller, and the Chinese and English interfaces can be selected.
3. Default program groups and steps, with a maximum setting of 99 hours and 59 minutes per period.
4. Start the test, the controller automatically runs and displays the real-time Humidity Linear dispersion.
5. Using test holes for experimental operation and Measuring temperature.
6. After the test is completed, the data is exported through a computer or USB interface for analysis and storage.
Notice
- Power supply voltage meets AC380V 50Hz requirement before use.
- Avoid manual touch screen lock function during operation to prevent changing data or unexpected downtime.
- Regularly check the built-in sink and add water in time to ensure proper Humidity control.
- Pay attention to the overheating and overcurrent protection of Compressors, fans and other components to avoid overload operation.
- Humidity alarm is monitored during the test, and any abnormalities are dealt with immediately.
- When cleaning the box, use imported 304 mirror stainless steel liner, pay attention to the safety of loading and unloading of shelf brackets.
