721N

Visible Spectrophotometer

The 721N visible Spectrophotometer uses microprocessor technology to conduct qualitative and quantitative analysis of substances in the visible spectrum region. It is a multi-purpose analytical instrument required in conventional laboratories.

main feature

Holographic blazed grating monochromator has the advantages of high Wavelength Accuracy, good monochromaticity and low stray light.

The comfortable large-screen LCD display with backlight makes the measurement data clear at a glance.

Using a microcomputer measurement system, the TA conversion accuracy is high, and it has automatic adjustment of 0% (T) and 100% (T), concentration factor setting, and direct reading of concentration.

The measurement readings are highly accurate, reproducible and stable.

Automatic light gate technology eliminates the need for black bodies and protects photoelectric sensors.
