3nh TS7708 Portable Spectrophotometer – Measurement geometry & functions: D/8 — with UV illumination & Bluetooth

The TS7000 series of handheld spectrophotometers has been developed for high-precision mobile colour measurement and professional quality control. The TS7708, TS7700 and TS7600 models combine state-of-the-art spectral technology, D/8 geometry, SCI/SCE measurement and powerful colour management functions in an ergonomic handheld device. With various aperture sizes, UV support and integrated camera positioning, the devices are ideal for use in laboratories, production, goods receipt and industrial colour communication.

The TS series enables reproducible colour and spectral measurements on a wide variety of materials and surfaces. Thanks to the combination of full-spectrum LED technology, planar grating spectroscopy and high-resolution CMOS sensors, the devices deliver stable and precise measurement results even under demanding production conditions.

Applications

The TS7000 series handheld spectrophotometers are suitable for:

Plastics and injection moulding industry
Paints, varnishes and coatings
Textile and clothing industry
Printing and packaging
Ceramics and building materials
Electronics and consumer goods
Cosmetics and food industry
Laboratory and research applications
Colour approval and production control

The UV models also enable precise measurements of fluorescent materials, optical brighteners and special effect surfaces. Thanks to multiple aperture sizes, both large areas and small, narrow or textured areas can be analysed with precision.

Special features

The devices have been specially developed for mobile and industrial use. Thanks to their ergonomic design, robust housing and high-performance lithium-ion batteries, the devices are ideal for use in laboratories, production environments and in the field.

Automatic white calibration ensures stable measurement results and reduces operator errors. The integrated camera positioning further improves accuracy on small or complex measurement surfaces. SCI/SCE technology also allows glossy surfaces and textured materials to be reliably assessed.
