L3S

Visible Spectrophotometer

Introduction

The L3S visible Spectrophotometer adopts a professional proportional monitoring dual-beam optical path system and low-noise circuit design, which has good reliability and stability. It can meet the application needs from daily analysis to scientific research.

main feature

Adopting professional optical, mechanical and electrical design, it has stable performance and ultra-high cost performance.
It adopts 8-inch color touch LCD display, which is flexible and convenient to operate.
It adopts a proportional monitoring double-beam optical path structure and is equipped with a high-performance "blazed holographic grating", a low stray light and high-resolution monochromator, which has outstanding optical precision, measurement accuracy, reproducibility and stability.
Unique automatic adjustment "0%" to "100%", automatic 8-cell cuvette holder.
It has full-band scanning (S model only), sub-band scanning (S model only), kinetic time scan, and various advanced functions such as GOTOÎ», linear regression, concentration direct reading, and peak and valley detection.
Using a thermal plotter (optional), it can perform data printing, spectral scanning (S model only), fixed-wavelength long-term scanning, linear regression and other curve drawings.
It has a USB interface and can directly interact with a PC, which strengthens the processing functions of the instrument such as detection data and scanned spectra, realizes mass storage of test documents, and also provides convenience for usersâ secondary development.
Professional power-off protection measures can memorize measured data, scanning spectra, regression equations, instrument correction values, etc., and enable quick initialization into the test state after power-on.
