Product Description
This temperature and humidity control system is a sealed working chamber required for precise weighing, which utilizes a state-of-the-art circulation method to draw the air with temperature and humidity from the chamber into a mixer. After filtration, the processed and stable air with temperature and humidity is then delivered back to the chamber, creating a complete closed-loop system. It completely avoids the interference from unstable external environmental temperature and humidity, as well as air pollution, on the measurement samples and the weighing results, thereby enhancing the accuracy of the weighing outcomes.
This product is a high-precision weighing device for various samples.

Equipment Features 1. A complete shock-absorption system is formed by the colloidal caster bracket, a horizontal marble platform, and silicone soft shock absorbers, ensuring high accuracy in weighing and weighing results under a tranquil and secure environment for the balance. 2. Round central support sample display stand, designed to accommodate different types of samples for weighing, with easy rotation for horizontal sampling. 3. The恒温恒湿system employs a stable extraction, diffusive treatment, and slow-flow circulation method to ensure uniform temperature and humidity inside the box and stable airflow. 4. The wide-angle glass door features two manual operation openings, ensuring that during manual operation, the constant temperature and humidity within the cabinet is unaffected and that there is no air exchange between the interior and exterior of the cabinet. 5. The split design, combined with a balance workbench, features multi-level vibration resistance, ensuring stable operation of the balance under non-vibrating conditions. 6. The entire top is equipped with a filtration system, ensuring the air inside the weighing chamber is clean, completely avoiding the弊端 of inaccurate batching due to murky air in weighing boxes currently on the market. It also guarantees low wind speed and high uniformity within the weighing chamber. 7. The full-color touch screen allows for real-time monitoring of the internal temperature and humidity of the container. After long-term operation, historical data and curves can be reviewed, making it convenient for us to understand the entire weighing process. |
