Overview
YIHENG High and Low Temperature (Alternating) Damping heat testing chamber is a new generation of environmental testing equipment, 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, in detail to meet customer requirements, to provide high-quality products.
Features
1. Humanized design: new fluorine-free design is adopted; there is a test hole on the left side of the box for easy operation; the built-in sink can be pulled out to add water, which is convenient for use.
2. Quality assurance: using brand Compressor and circulating fan, uniform temperature distribution; using environmentally friendly refrigerant (R134a), high efficiency and low energy consumption; unique air duct circulation system to ensure uniform temperature and humidity; using imported 304 mirror stainless steel liner, easy to clean; multi-stage programmable control to achieve automatic operation.
3. Safety function: with independent temperature limit alarm system, over-temperature automatic interruption and sound and light alarm; with 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), use a computer to display and print temperature, humidity and time Linear dispersion.
5. Programmable touch screen controller (BPHJS series standard): using color LCD touch control screen, menu operation interface; Chinese and English operation interface optional, screen display real-time running Linear dispersion; can preset 100 groups of programs; with screen lock function; with P.I.D automatic calculation function to make the control more accurate; with RS-232 or RS-485 communication interface, can be programmed and monitored on the computer; professional control software can realize simultaneous monitoring and control of 9 devices, data can be formed Excel or Word documents.
Principle
The test chamber is precisely controlled by a multi-functional multi-stage programmable temperature and humidity controller (fuzzy PID controller) of dry and wet ball type or electric kiln type. Brand Compressor and circulating fan are used, and a unique air duct circulation system is used to distribute the temperature and humidity evenly in the working room. Through preset programs, automated high and low temperature and heat and humidity alternating test processes are realized.
Applications
Not mentioned
Steps
1. Perform parameter setting and program programming through keyboard or touch screen.
2. Place the sample on the shelf in the studio.
3. Connect the test instrument (if necessary) through the test hole on the left side of the box.
4. Pull out the built-in sink to add water.
5. Start the device and run the preset test program.
6. Monitor the test process and data through the controller screen or connected computer.
7. After the test is completed, remove the sample.
Notice
Pay attention to the safety alarm function of the equipment. In case of over-temperature alarm, it is necessary to deal with it in time.
* Pay attention to the overheating protection of Compressor, fan and other components during operation.
Make sure the water supply is normal during the test to avoid triggering water shortage protection.
When using the touchscreen controller, the screen lock function can be enabled to prevent incorrect operation.
When transferring data or connecting to a computer, ensure that the interface and operation are correct.
* When cleaning the box, the shelf bracket can be removed for easy cleaning.
