China 7230g Visible Spectrophotometer

Features:

1. It adopts 128*64 dots LCD display, which display standard curve and measuring data directly. The main machine can store measuring data and assort with printer to print.

2. USB data output interface, which assorted with professional software YOKE3.0 to perform.

3. It can establish standard curve to perform relevant testing, which can test and store 200 groups of data continuously and 100 standards curve that named by users.

4. Distinctive light system, high-performance grating and imported acceptor ensure superior performances of instrument.

5. Auto-adjusting and auto-setting wavelength.

6. Wide sample-room can accommodate all kinds of 5-100mm cuvette.

7. Ultrathin button makes operation simple and convenient.
