Highlights
High precision & accuracy
- Two internal balances away from high temperature and heat radiation, no drift occurs.
- With automatic calibration function, each weighing is accurate and reliable.
- Simulate test environment and condition of drying oven and muffle furnace, exact in accordance with standard.
- The unique automatic cleaning function of low temperature furnace completely eliminates the influence of dust on result.
High efficiency
- Dual furnaces design, low-temperature furnace for moisture test and high- temperature furnace for ash and volatile matter test.
- Analysis for moisture, ash and volatile matter can be conducted simultaneously and consecutively.
- No blank sample during test. Full index of single batch samples (18 samples) can be finished in 150 min.
Patented technology
- Tailored volatile matter crucible with unique auto-sample loading mechanism avoided the operation of replacement or removal of the crucible cover under high temperature.
- Unique crucible clamp device avoid upset and drop of crucible.
- Unique crucible detection mechanism avoid mistake and missing of placing crucible.
- Unique sample tray positioning mechanism and drive mechanism ensure stable and reliable operation.
Human based design, Environment friendly and energy saving
- Sample tray locates inside, real time data transmission. Weighing sample at room temperature, away from heat radiation.
- Special crucible collector discards residual automatically. No need to clamp crucible at high temperature. Easy and safe operation.
- Equipped with dust collector, environment friendly and clean.
- Compressed air can meet the requirement of gas supply, no oxygen and nitrogen required.
Intelligent control
- Easy to use Windows-based operating software, after finishing the sample weighing, the operator can be free for other tasks.
- Several proximate analyzers can be controlled by a single PC with Ethernet communication technology.
- Strong data processing ability, statistic report and print function, connection with network and balance are available by standard interface RS232.
