ST-UV-755B UV-VIS Spectrophotometer

Model: ST-UV-755B
Category: UV-VIS
View:
    Feature:
    • It adopts 128*64-bit dot matrix LCD display, which can directly display standard curve and test data. The host can store test data and print data with optional printer.
    • It has USB data output interface for on-line operation with special soft.
    • It can establish standard curve directly to have correlative test. The instrument can test   and store 200 sets of data continually, and can store 100 standard curve. Users can name and use it directly.
    • The Unique design of optical system, high-performance 1200 A/mm grating and imported receiver can ensure excellent performance of the instrument.
    • It can calibrate and set wavelength automatically.
    • The wide sample room can accommodate 5-100 mm cuvette of various specifications.
    • It has metal dome, which is simple and easy to operate.
