Technical characteristics of products
1. Miniaturization design, saving space, easy to carry
2. COTREM-M3 microprocessors with higher performance than ARM7
3. Full digital output design can be controlled by chromatographic workstation through RS-232/485 interface.
4. It has analog output port and is applied to third-party analog workstation.
5. Grating is directly fixed on the motor axis of stepping motor. After sinusoidal conversion by single-chip computer program, the motor is controlled to select the wavelength, which replaces the traditional sinusoidal bar mechanism and further improves the reliability and stability of the system.
6. Wavelength calibration is performed immediately after boot-up.
7. The flow pool is designed in Z-shape, and the flow pool is treated at constant temperature, which can greatly improve the noise and drift of the instrument.
8. Dual-beam design further reduces the influence of environmental changes on drift.
9. Flow pools can be selected according to sensitivity and velocity range.
10. Typical analytical optical path is 10 mm, high flow rate and high concentration detection optical path is 0.5 mm.
11. The maximum velocity can reach 10L.
12. The wavelength can be programmed and controlled, and the stop-flow automatic spectral scanning can be implemented.
13. Full digital output design, which can be controlled externally through RS-232/485 interface intelligently identified, and data acquisition by chromatographic workstation software
14. Seamless docking design with software HW2000 of Shanghai Qianpu Workstation
15. Vehicle power supply makes it suitable for field operation
