1. Extra large working chamber: equipped with height-adjustable stainless steel partitions to detect multiple temperature and humidity meters, greatly improving detection efficiency.
2. The inner liner of the studio is made of stainless steel and has no dead ends. It has a reasonable layout and a uniform temperature and humidity field. Rotating hangers can be added according to customer needs to facilitate the reliable placement of the instruments under inspection and easy access, thereby eliminating the placement of the instruments under inspection. If placed unevenly, the calibration environment will be affected.
3. It is designed with three observation windows and a special platform for placing the dew point meter outside the box. With 2 test holes, the inspector can put his hands into the box without opening the box door and adjust the instrument under test directly in the box, reducing the impact on the test environment in the studio during adjustment.
4. The temperature control of the temperature and humidity calibration box adopts dual-compressor equal-plate heating technology. The time from normal temperature (such as 25ºC) to -30ºC shall not exceed 70 minutes, and the time from normal temperature (such as 25ºC) to 60ºC shall not exceed 70 minutes. The time does not exceed 30 minutes, and it can be stable within 10 minutes when it rises to this temperature point; the humidity control method of the temperature and humidity calibration box adopts the split flow method.
5. Intelligent auxiliary calibration system software, the system automatically controls the temperature and humidity of the calibration box, monitors the temperature and humidity value of the calibration box in real time through the dew point meter, and automatically makes stability judgments. When the stability conditions are met, the system automatically collects standard data, and then notifies the user to enter the inspected data through multimedia voice prompts. After clicking OK, the system will continue to run automatically. The next time the conditions are met, the system will continue to prompt the user to enter data through multimedia voice. After the verification is completed, the verification results are automatically calculated and the verification conclusion is given.
6. It has the function of automatic real-time calculation of fluctuations, which can automatically calculate the current temperature and humidity fluctuations of the temperature and humidity calibration box, and determine whether the calibration box is stable. If it is stable, the measurement and calibration work can be started.
7. The fluctuation calculation period can be set freely (1min, 5min, 10min, 20min, 30min).
8. It has an intelligent stability prompt function, which can automatically determine whether the calibration box is stable based on parameters such as temperature and humidity deviation, fluctuation, and stabilization time of the calibration box. After stabilization, a green prompt "Temperature and humidity has stabilized" will appear on the screen, and you can start reading as a metrology teacher. reference to improve verification efficiency.
9. Compressor start and stop, overheating protection (over-temperature protection), anti-dry protection, low liquid level reminder to add water, and automatic rehydration can provide multiple protection functions.
10. Supports 12-point correction, touch screen, supports multi-touch, you can drag and zoom with two fingers to view local and overall curve details (the same way as zooming pictures on a mobile phone). The curve supports one-click screenshots and saves the curve data in a picture format. , supports data export as a maintenance and data process record.
11. It has multi-stage programming function, which supports the programming of commonly used temperature and humidity calibration points into the calibration box in advance, one-click start (timed start), and automatic execution in sequence; there is no need to repeatedly set the temperature and humidity points every time.
12. There is a defrost setting to ensure that it can be used continuously for 24 hours without frost.
