Features: 1. The unique active inspiratory collection tube condenser, has the stable air flow, 2. With the function of smudgy forecast, in the collection tube dirt to affect measuring accuracy, the device automatically reported. 3. "Gerdien Tube" congenital air collector has excellent electrostatic shielding function, better able to overcome the electrostatic adverse effect on the measurement. 4. The device with a built-in real-time clock, all the data had a time tag, convenient background data management. 5. Machines of green environmental protection, low power consumption, according to the weather condition, can use solar battery power supply, so as to save 220 ac power supply, greatly convenient installation. 6. Advanced automatic working mode, manual processing, electricity work automatically, data is automatically saved. 7. GPRS wireless communication functions, managers can be anywhere in the country, remote access to equipment data. 8. Provide RS232 interface, can be embedded in the client system. 9. The use of special materials, insulation materials, strong ability to resist tide, guarantee in high humidity environment frost, condensation, normal work. 10. When the environment temperature is below - 8 ℃, start heating. 11. B/S structure software distributed the background, clear interface, simple operation, good stability. 12. The system software interface is rich, the data can be saved to the database (Oracle, SQL Server, Access) or EXCEL and text file.
