|
Sample Degassing Station |
1. Independent degassing station, completely separated from the main unit. 2. Total quantity: 4 stations. 3. Three degassing modes: Standard mode, Water‑rich sample mode and Ultra‑light sample mode, meeting the testing requirements of various samples. 4. Equipped with automatic dehydration time judgment function, solving the problem of uncertain processing time for new product R&D samples. 5. Dual‑module control, every 2 stations form one group. 6. Heating furnace: Metal isothermal body heating; operating temperature range: Room temperature ~ 400℃ |
|
Testing Efficiency |
3 samples can be analyzed simultaneously while 4 samples are processed for degassing |
|
Testing Performance |
Each analysis port supports the analysis of ultra‑micropore, micropore, mesopore, macropore and samples with ultra‑small specific surface area |
|
Pressure Detection System |
Pressure Sensors: Each analysis station is equipped with three‑range pressure sensors, 10 sensors in total, including 3 pcs of 0.1 Torr sensors, 3 pcs of 10 Torr sensors and 4 pcs of 1000 Torr sensors. Pressure Sensor Accuracy: ±0.1% of full scale for 0.1 Torr, 10 Torr and 1000 Torr sensors. P/P₀ Measurement Range: 5×10⁻⁹ ‑ 0.998. P/P₀ Pressure Resolution: 1×10⁻¹⁰ |
|
Constant Dead Volume |
