NIR DW-EXPEC1350 Near-infrared Spectroscopy
DW-EXPEC1350 Analyzer is a universal mobile portable analyzer with a compact size, built-in rechargeable battery, mass storage device and LCD module. Through different measuring accessories, it enables non-destructive rapid testing of some physical and chemical components in particle, powder and liquid samples, which is widely used in inspection of textile fiber and food quality, as well as scientific research.
Measuring Accessories of NIR DW-EXPEC1350 Near-infrared Spectroscopy
It provides a variety of measurement methods by connecting different types of probes and accessories.
1. The light source plane diffuse reflection probe supports diffuse reflection detection mode, and sample testing of flake, particle, paste and powder, such as the non-destructive testing of cloth, fruits, grains, plastics, papers and tobaccos.
2. Optical fiber diffuse reflection probe supports diffuse reflection and transflection detection modes. The former one is applicable to single-grain sample testing, such as non-destructive testing of small fruit products and on-site testing of meat. The other is for transparent liquid sample testing, including on-site testing of edible oil and fuel oil.
3. The cuvette rack supports transmission detection mode, which is mainly used in liquid sample testing.
