On-site Testing Series
Portable Solid Analyser Pen
NT-BL-G1
A portable spectral laboratory: aim at a solid sample and press the button to obtain a composition assessment in the VISPEK app within 10 seconds, without sample preparation or damage.
Results in 10 Seconds : One scan takes 1–10 s, with results delivered to the app
Non-destructive Testing : Reflectance spectroscopy; no contact with or damage to the sample
Full-spectrum Sensing : 240–1700nm · 44 channels · Si + InGaAs
