Overview
YIHENG BPHJ-250A high and low temperature (alternating) test 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, in every detail to meet customer requirements, to provide customers with high-quality products.
Features
1. Humanized design: New fluorine-free design, long life of imported temperature Humidity controller, High Accuracy CFL20 word × 6 line LCD display, easy keyboard input operation, 25mm or 50mm diameter test hole on the left side of the box for experimental operation and Measuring temperature.
2. Quality assurance: imported brand Compressors and circulating fans make the temperature distribution uniform, environmentally friendly refrigerant efficiency is high and energy consumption is low to promote energy saving, unique air duct circulation system ensures uniform working room temperature Humidity, using imported 304 mirror stainless steel liner four corners and a half arc excessive, shelf bracket can be freely loaded and unloaded for easy cleaning in the box, multi-stage programmable control simplifies the complex test process to achieve automatic control and operation.
3. Safety function: independent temperature limit alarm system exceeds the limit temperature automatically interrupt operation and sound and light alarm prompt, temperature is high, low 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), with a computer to display and print Humidity and Time Linear dispersion, for the test process data storage and playback to provide assurance.
5. Programmable Touchscreen Controller (Standard): Color LCD touch screen Menu Operating interface Observation intuitive and easy to operate, Chinese and English Operating interface Can be arbitrarily selected Screen display Instant temperature Humidity Run Linear dispersion, can be set up 120 groups Each group of 99 segments 999 cycles Each segment can be set for 999 hours 59 minutes 59 seconds, with screen lock function to avoid human touch to change data or stop, with P.I.D automatic calculation function Correction of temperature Humidity change conditions to make the control more accurate and stable, with RS-232 or RS-485 Communication interface Design programs on the computer to monitor the test process and execute the switch machine, install professional control software to monitor and control 30 devices at the same time, analyze and store data in real time on the computer to form Excel or Word documents Print.
Principle
High-efficiency refrigeration is achieved through imported brand Compressors and environmentally friendly refrigerants, combined with a unique air duct circulation system to ensure uniform distribution of working room temperature Humidity, and a programmable controller is used to automatically adjust temperature Humidity parameters to achieve accurate control and stable operation.
Applications
High and low temperature environment test, alternating temperature Humidity test, product Reliability verification, material performance evaluation
Steps
1. Connect the power supply to AC220V 50Hz.
2. Enter the Humidity parameter via keyboard or Touchscreen.
3. Set the number of programmable segments and cycles.
4. Start the equipment operation test.
5. Measuring temperature through the test hole.
6. Use the Interface to connect to a computer for data monitoring and storage.
Notice
Avoid human touch screen lock function to prevent changing test data or downtime.
● Pay attention to the independent temperature limit alarm system prompt, and the operation will be automatically interrupted if the temperature exceeds the limit.
● Ensure that the Compressor, fan and other protection functions are normal to prevent overheating, overcurrent and overload.
● Use environmentally friendly refrigerants and pay attention to fluorine-free design.
● Regularly clean the imported 304 mirror stainless steel liner, pay attention to safety when loading and unloading shelf brackets.
