Overview
YIHENG BPHJS-250A High and low temperature (alternating) Damping heat testing chamber is a new generation of products, integrating the company's many years of successful experience in box design, in line with the humanized design concept, starting from the actual needs of customers, meeting customer requirements in details, and providing high-quality products.
Features
1. Humanized design: Fluorine-free design supports healthy life; using wet and dry bulb or electric kiln type multi-functional multi-stage programmable temperature and Humidity controller, fuzzy PID controller, temperature and humidity control accurate fluctuation is small; Imported temperature and Humidity controller has long life, High Accuracy CFL20 word × 6 line LCD display, keyboard input, 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 and a half corners are excessive, shelf bracket can be freely loaded and unloaded, 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.
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 Operating interface, intuitive observation, easy to operate; Chinese and English Operating interface can be arbitrarily selected, the screen shows real-time temperature Humidity Run Linear dispersion; 100 groups can be preset 1000 steps 999 cycles, each time set up to 99 hours 59 minutes; with screen lock function to avoid human touch to change data or stop; with P.I.D automatic calculation function, correct temperature Humidity change conditions, make the control more accurate and stable; with RS-232 or RS-485 Communication interface, can design programs on the computer, monitor the test process and execute the switch machine; install professional control software to monitor and control 9 devices at the same time; real-time on the computer Analyze and store data to form Excel or Word documents for easy printing.
Principle
The test chamber adopts dry and wet bulb or electric kiln multi-function multi-stage programmable temperature and Humidity controller, combined with fuzzy PID controller, to achieve precise temperature control and humidity control. Through brand Compressor and circulating fan, with environmentally friendly refrigerant and unique air duct circulation system, ensure the even distribution of working room temperature Humidity. The safety system includes independent temperature limit alarm and multiple protection mechanisms to ensure the safe operation of the experiment.
Applications
High and low temperature (alternating) Damping heat testing chamber is widely used in electronics, automotive, aerospace, material testing, scientific research and other fields.
Steps
1. Use the keyboard or Touchscreen to enter parameters and operate through the LCD display.
2. Preset program groups and steps, and set time parameters.
3. Connect external devices such as printers or computers for data monitoring and storage.
4. Start the test, and the system automatically controls the change of Temperature and Humidity.
5. During the experiment, measurement and operation can be carried out through the test hole.
Notice
• Avoid human touch screen lock function to prevent data change or downtime.
• Pay attention to Compressor overheating, overcurrent, overload protection, and fan overheating and water shortage protection.
• Use environmentally friendly refrigerants to ensure safe operation.
• Regularly clean liner and shelf supports to keep the box hygienic.
