Asia Pacific Senbo (Guangdong) Paper Co., Ltd. uses the following equipment manufactured by Changsha Youxin Instrument Manufacturing Co., Ltd.:

YX-ZR9704 Automatic Calorimeter

Technical Features

1. Employing advanced multi‑probe temperature‑sensing technology, the system continuously monitors the inner‑cylinder water temperature, the outer‑cylinder water temperature, the ambient room temperature, and the temperature‑controlled water‑tank temperature. Coupled with a constant‑temperature water circulation system, it supports both adaptive‑temperature and fixed‑temperature operating modes. In adaptive‑temperature mode, the water temperature tracks changes in the room temperature, effectively addressing the heat exchange between the outer‑cylinder water and the indoor air that occurs during testing under the fixed‑temperature mode, thereby eliminating the primary factor that can compromise calorimeter measurement results.

2. A unique pump‑circulation method ensures uniform temperature distribution throughout the calorimeter, thereby guaranteeing the accuracy of the test results.

3. Equipped with a self-developed automatic oxygen‑injection and venting device and an automated oxygen‑bomb lifting mechanism, it eliminates the need for manual oxygen charging and venting, achieving a high degree of automation and ensuring simple, convenient operation.

4. Utilizing imported thermal insulation materials, the instrument effectively isolates itself from external environmental influences, resulting in enhanced anti-interference performance.

5. Equipped with a high-precision probe-type electronic measuring cup, it eliminates the need for manual water weighing and automatically measures the water volume in the inner cylinder. With a repeatability error of less than 0.5 g, it delivers more accurate water measurements, shorter test times, rapid and precise results, and simple, convenient operation.

6. Automatic ignition wire detection function, accurately identifying faulty ignition wires.

7. Can be integrated with the laboratory management system to ensure that balance data is not stored locally and that test results are backed up and uploaded.

8. For solid waste samples, optional accessories such as a specially designed oxygen bomb and crucibles are available.

9. An optional oxygen bomb gas collection device is available for collecting gases inside the oxygen bomb.

YX-GYFX7705 Fully Automatic Industrial Analyzer

Technical features:

1. The instrument employs a multi-furnace, dual‑balance configuration; the volatile‑matter analysis module is equipped with a dedicated temperature‑controlled chamber and requires no external gases. Moisture, ash, and volatile matter can be determined either in any combination or individually. Using the rapid method, simultaneous determination of these three parameters for 19 samples can be completed within 100 minutes.

2. Employing thermogravimetric analysis, the system features automatic sample weighing, automated sample introduction, automatic data processing, result calculation, report printing, and data storage, enabling unattended operation.

3. During the experiment, there is no need to remove or replace the crucible lid, nor to load or retrieve samples. A pneumatic lid‑flipping mechanism is employed, protecting operators from high‑temperature radiation and burns. Compressed air can be supplied either from bottled gas or a silent air compressor to power the pneumatic system and assist combustion.

4. Can be integrated with the laboratory management system to ensure that balance data is not stored locally and that test results are backed up and uploaded.

YX-DL8500 Automatic Sulfur Analyzer

Technical Features

◎ It adopts a horizontal integrated design, ingeniously integrating components such as the automatic sample‑feeding and injection mechanism, the high‑temperature pyrolysis furnace, the electrolytic cell, the stirrer, and the air‑purification system, thereby making the instrument’s structure more compact, more rational, and more stable.

◎ It employs a specially designed flat-bottomed corundum ceramic boat to minimize sample sticking. Program-controlled operation enables automatic heating, temperature regulation, sample introduction, and analysis; results are automatically saved and printed, and samples can be added mid‑run, significantly enhancing work efficiency and enabling truly unattended operation.

◎ The determination is performed using coulometric titration, with the analysis time automatically adjusted according to the sample type; this method offers superior speed compared to the Eschka gravimetric method and the high‑temperature combustion–neutralization method.

◎ Employs a linear electrolyte concentration acquisition circuit, effectively addressing the issue of electrolyte over‑consumption.

◎ Employs a contactless switch, featuring open-circuit protection, hardware over-temperature protection, and measures to prevent electrolyte backflow.

◎ A multi-point dynamic coefficient correction method is employed to ensure higher accuracy in test results for coals with high, medium, and low sulfur contents.

◎ Can be integrated with the laboratory management system to ensure that balance data is never stored locally and that test results are backed up and uploaded.

◎It can be used to determine the total sulfur content in samples such as solid hazardous waste.

YX-WK7300 Intelligent Muffle Furnace

Technical features:

1. It employs a microcontroller-based control system, a digital tube display module, and membrane‑type pushbuttons for convenient operation.

2. It employs a PID temperature-control algorithm, achieving higher temperature-control accuracy.

3. Temperature control is precise and timely; the optional test module allows users to conveniently perform post‑combustion checks or, at the user’s discretion, adjust temperature and duration settings.

4. The furnace chamber is constructed from polycrystalline mullite fiber, providing a wide constant-temperature zone, stable temperature control, and rapid heating and cooling rates—capable of reaching 920°C in just 15 minutes—and enabling multiple experiments to be repeated throughout the day.

5. The control board employs a novel temperature‑conversion chip calibrated by laser etching, featuring cold‑junction compensation, open‑circuit protection, and software‑based overtemperature protection.

6. An optional pallet layout platform is available, facilitating layout operations during quick‑lime testing.

7. An electronic lock option is available to prevent unauthorized opening or closing of the furnace door during testing.

8. Can be integrated with the laboratory management system to enable backup and upload of test results.
