Features
1. The chamber is molded from epoxy fiberglass. Asbestos board is pasted inside the jacket. It is resistant to high temperature and corrosion, lightweight, and has high strength. Both the inner and outer walls of the chamber are smooth and easy to clean.
2. The chamber cover is made of epoxy fiberglass with a top cover temperature of 100 - 200°C to prevent condensed water in the chamber from dripping directly onto the test specimens.
3. Heater: The nickel - chromium alloy heating wire heats from the bottom, forming jacket heating to ensure good temperature uniformity inside the chamber.
4. Humidification method: Humidification by a steam generator.
5. Input methods for sulfur dioxide and hydrogen sulfide: Input from cylinders, and both input and discharge are quantitatively controlled by concentration sensors.
6. Exhaust gas treatment: Install treatment devices for sulfur dioxide and hydrogen sulfide gases. After multi - stage treatment with sodium bicarbonate, the exhaust gas meets the discharge standards (the purification device is external).
Control System
1. Temperature control: Japanese Fuji temperature controller
2. Temperature input: PT100; Output: Driven by SSR
3. Display range: 0 - 100°C
4. Control range: RT + 5 - 55°C
5. Cycle used (measurement filtering): 2 - 3s
6. The main control components are products from joint - venture companies.
7. The temperature is controlled by a solid - state relay, with stable performance and no noise.
8. A fan is used for stirring and circulation inside the chamber.
9. Display and control of sulfur dioxide concentration
Technical Parameters
1. Temperature range: 10 - 55°C
2. Temperature fluctuation: ±0.5°C
3. Temperature uniformity: ±2°C
4. Sulfur dioxide gas concentration: 100ppb - 50000ppb (0.1ppm - 50ppm)
5. Hydrogen sulfide gas concentration: 10ppb - 5000ppb (0.01ppm - 5ppm)
6. Relative humidity: 75±3%
7. Tests with sulfur dioxide, hydrogen sulfide, and mixed gases of sulfur dioxide and hydrogen sulfide can be conducted.
Maintenance Information
(1) Regularly inspect gas pipelines and seals for leakage.
(2) Maintain and replace gas purification materials as required.
(3) Clean the chamber interior after testing to prevent residue buildup.
(4) Calibrate temperature, humidity, and gas sensors periodically.
(5) Ensure proper ventilation and safe operation during use.
