Humanized design
● The new fluorine-free design keeps you at the forefront of healthy life.
● Using dry and wet bulb or capacitive multi-function multi-stage programmable temperature and humidity controller, fuzzy PID controller, precise temperature and humidity control with small fluctuations.
● Imported temperature and humidity controller with long service life, high-precision CFL20 characters × 6 lines 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 temperature measurement.
● The built-in water tank can be pulled out to add water, which is convenient to use.

Quality Assurance
● International brand compressors and circulating fans make the temperature evenly distributed. Environmentally friendly refrigerant (R134a) has high efficiency and low energy consumption, promoting energy saving.
● Unique air duct circulation system to ensure uniform working temperature and humidity.
● Adopt imported 304 mirror stainless steel liner, the semi-circular arc at four corners is excessive, and the shelf bracket can be freely installed and removed, which is convenient for cleaning in the box.
● Multi-segment programmable control can simplify the complex test process and truly realize automatic control and operation.

Security function
● Independent temperature limit alarm system, if the temperature exceeds the limit, the operation will be automatically interrupted, and the operator will be reminded by sound and light alarm. To ensure the safe operation of the experiment without accidents.
● High temperature, low temperature and over temperature alarm.
● Compressor overheating, overcurrent, overload protection, fan overheating protection, water shortage protection, etc.

Convenient data processing (optional)
● It can be connected to a printer or 485 communication interface, with a USB data transfer interface (SD disk), which can be displayed on a computer, and print the temperature, humidity and time curves, providing a strong guarantee for data storage and playback during the test process.

Programmable touch screen controller (standard for BPHJS series)
● Adopt color LCD touch control screen, menu-type operation interface, intuitive observation and easy operation.
● Chinese and English operation interface can be selected arbitrarily, and the screen can display the real-time temperature and humidity running curve.
● 120 groups of 99 segments, 999 cycles can be set, and each segment can be set to 999 hours, 59 minutes, and 59 seconds.
● With screen lock function, avoid changing test data or downtime by human touch.
● With P.I.D automatic calculation function, the temperature and humidity change conditions can be corrected immediately, making the temperature and humidity control more accurate and stable.
● With RS-232 or RS-485 communication interface, you can design programs on the computer, monitor the test process and perform functions such as switching on and off.
● Install professional control software on the computer, which can monitor and control 43 devices at the same time.
● Real-time analysis and storage of data on the computer to form Excel documents or Word documents for easy printing.
