High and low temperature alternating testing machine manufacturer price

Shenzhen high and low temperature alternating test machine manufacturer, quotation for high and low temperature alternating test box, Guangzhou high and low temperature test machine, Foshan temperature cycling test box

CHARACTERISTICS

1. High quality appearance, the body adopts a circular arc shape, the surface is treated with matte stripes, processed by CNC machine tools, and adopts a flat non reactive handle, which is easy to operate, safe and reliable, with a beautiful and elegant appearance and novelty.
2. Rectangular laminated glass observation window, large observation window with lighting fixtures to keep the inside of the box bright, and using double-layer glass for clear observation of the test sample at any time. The window is equipped with an anti sweat electric heater device to prevent water vapor condensation and water droplets, and a high brightness PL fluorescent lamp to keep the inside of the box illuminated.
3. The double-layer isolation and airtightness of the box door can effectively isolate internal temperature leakage.
4. Equipped with an external water supply system, it is convenient to supplement the humidification tank water supply and automatically recycle it for use
5. The compressor circulation system adopts the French brand "Taikang", which can effectively remove lubricating oil between the condenser and capillary tubes, and the entire series uses environmentally friendly refrigerants (R23, R404, R507).
6. TIME880 touch sensitive from South Korea. Fixed conditions can be set for a time range of 0-999 hours, with a touch sensitive KEY BOARD. Nine point fault warnings and simple maintenance methods can be set for fixed or alternating strips. The temperature rise and fall can be controlled by slope, and it has the function of self correcting temperature reference points The temperature sensor adopts DIN PT-100 Ω (platinum sensing) The temperature control is synchronized and coordinated using the P.I.D. S.S.R. system, which can improve the stability and lifespan of control components and interfaces.
7. It has the function of P.I.D. automatic calculation, which can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable, and reducing the inconvenience caused by manual setting.

2、 Control system

1. The temperature and humidity control instrument adopts a "Korean original TEMI850" large screen - LCD display - programmable microcomputer PID control SSR output operation. Fully imported large LCD touch screen display, simple screen operation, and easy program editing.

2. Accuracy: 0.1 ℃ (display range)

3. Resolution: ± 0.1 ℃;

4. Temperature sensor: PT100 platinum resistance thermometer;

5. Control mode: thermal balance temperature and humidity control mode; All electrical appliances use Schneider series products

6. Temperature and humidity control adopts P I . Coordination control of D+S.R. system on the same channel

7. Equipped with automatic calculation function, it can immediately correct temperature change conditions, making temperature control more precise and stable

8. The controller operation interface is available in both Chinese and English, and the real-time operation curve chart can be displayed on the screen

9. The HD80 high and low temperature testing machine has a capacity of 100 programs, 100 segments per group, and 999 cycles per segment. The maximum value set for each segment is 99 hours and 59 minutes

10. After inputting the data and experimental conditions, the controller has a screen lock function to avoid manual touch and shutdown

11. Equipped with RS-232 or RS-485 remote communication interface, the HD80 high and low temperature testing machine can be programmed on a computer to monitor the testing process and perform functions such as automatic power on/off

12. The controller has an automatic screen saver function, which better protects the LCD screen during long-term operation (making its lifespan longer)

13. The return air outlet of this test chamber is equipped with an automatic defrosting device (so that the water vapor generated during the test will not accumulate on the refrigeration evaporator)
