Overview
A new generation of high and low temperature (alternating) test Chamber, the company has many years of successful experience in box design, in line with the humanized design concept, starting from the actual needs of customers, in every detail to meet customer requirements, to provide customers with high-quality products.
Features
1. Humanized design: The new fluorine-free design makes you always walk in front of healthy life; Imported temperature Humidity controller has long life, High Accuracy CFL20 word × 6 line LCD display, keyboard input, easy operation; There is a 25mm diameter or 50mm test hole on the left side of the box, which is convenient for experimental operation and Measuring temperature.
2. Quality assurance: imported brand Compressor and circulating fan, so that the temperature distribution is uniform; high efficiency of environmentally friendly refrigerant, low energy consumption, promote energy saving; unique air duct circulation system to ensure uniform working room temperature Humidity; imported 304 mirror stainless steel liner, four corners and a half arc over, shelf bracket can be freely loaded and unloaded, easy to clean the box; multi-stage programmable control, can simplify the complex test process, truly realize automatic control and operation.
3. Safety function: independent temperature limit alarm system, if the temperature exceeds the limit, the operation will be automatically interrupted, and the sound and light alarm will prompt the operator to ensure the safe operation of the experiment without accident; high temperature, low temperature and over-temperature alarm; Compressor overheating, overcurrent, overload protection, fan overheating protection, etc.
4. Convenient data processing (optional): can be connected to a printer or 485 Communication interface, with USB data transfer interface (SD disk), display with a computer, and print Humidity and Time Linear dispersion, providing a strong guarantee for data storage and playback during the test process.
5. Programmable Touchscreen Controller (BPHJ series standard): Adopt color LCD touch control screen, menu-type Operating interface, intuitive observation and easy operation; Operating interface in Chinese and English can be selected arbitrarily, and the screen can display immediate Temperature Humidity Run Linear dispersion; can be set up 120 groups of 99 segments each, 999 cycles, each segment can be set for 999 hours 59 minutes, 59 seconds; with screen lock function to avoid human touch and change the test data or stop; with P.I.D automatic calculation function, can immediately correct the temperature Humidity change conditions, making the temperature Humidity control more accurate and stable; with RS-232 or RS-485 Communication interface, can design programs on the computer, monitor the test process and perform functions such as switching machine; Installing professional control software on the computer allows for the simultaneous monitoring and control of 30 devices. Analyze and store data in real time on the computer to form Excel documents or Word documents for easy printing.
Principle
Through imported brand Compressors and environmentally friendly refrigerants to achieve refrigeration, combined with a unique air duct circulation system, the temperature distribution is uniform; programmable Touchscreen controller is used for multi-stage programmable control to achieve automatic control and operation; through independent temperature limit alarm system and a variety of protection mechanisms to ensure safety.
Steps
1. Use keyboard input or Touchscreen to operate the controller and set the Temperature Humidity parameter.
2. Set up multi-stage test procedures through programmable functions, including the number of groups, stages, cycles, and times.
3. Interface (such as RS-232 or RS-485) for computer monitoring and Data storage.
4. Start the equipment, the system automatically runs and monitors temperature and Humidity changes.
5. After the experiment is completed, export the data through the Interface or print Linear dispersion.
Notice
• Avoid data changes or downtime caused by human touch of the screen, and use the screen lock function.
• Pay attention to the over-temperature alarm and deal with abnormal situations in time.
• Power supply voltage AC380V 50Hz to avoid overload.
• Regularly clean the box and use removable shelves for easy cleaning.
• Use environmentally friendly refrigerants and pay attention to fluorine-free design.
