CHNSpec handheld portable spectrophotometers provide dependable quality control on production floors, incoming receiving docks, and field service inspection. Integrated DS-87CG models combine D/8 color measurement with 60-degree gloss verification in a single scanning sequence.
Featuring digital camera viewfinder alignment and automatic contact-free magnetic calibration bases, they ensure reproducible measurements across shifts.
Selection parameters: aperture size, integrated 60-degree gloss sensor, battery autonomy, and mobile app connectivity.
ColorMeter Pro, ColorMeter MAX & CR Series Digital Colorimeters
Compact digital colorimeters from CHNSpec deliver instant color difference verification based on CIE Lab, LCh, ΔE*ab, and ΔE*00 formulas. ColorMeter Pro and MAX instruments link seamlessly via Bluetooth to iOS/Android mobile applications and cloud color databases including Pantone, RAL, and NCS.
Operators quickly match target color recipes and monitor production batch consistency directly at the line.
TH-09, TH-100, CS-700 & DH-12 Haze & Total Transmittance Meters
CHNSpec benchtop haze meters execute standardized optical clarity testing for haze percentage and total luminous transmittance on polymer films, PC sheets, glass panels, and liquid cells.
Certified to ASTM D1003, ASTM D1044, ISO 13468, and ISO 14782 methodologies, they operate with CIE Illuminant C and A standard light sources. An unobstructed measurement chamber accommodates oversized sheets without edge cropping.
Selection parameters: ASTM D1003 compliance, 154 mm integrating sphere, vertical/horizontal mounting, and liquid test cells.
CS-300 SE, CS-380 SE & DG-60 Multi-Angle & Single-Angle Gloss Meters
Precision digital gloss meters from CHNSpec deliver fast evaluation of specular reflectance across automotive body panels, decorative polymers, stone, ceramics, and printed packaging. Flagship model CS-380 SE simultaneously captures 20°, 60°, and 85° reflection angles spanning 0.1 to 1000 GU.
Onboard thermal drift compensation and a protected ceramic calibration tile in the dock maintain calibration integrity.
Selection parameters: measurement geometry (20°/60°/85°), gloss range (up to 1000 GU), aperture dimension, and ISO 2813 conformance.
CRX-50, CRX-51 & CRX-52 Non-Contact Inline Color Inspection Systems
Industrial inline spectrophotometers from CHNSpec provide non-destructive 100% color monitoring on high-speed continuous production lines.
Suitable for film extrusion, coil coating, synthetic paper webs, and textile finishing plants, the separated optical head reads surface pigmentation from 10 to 150 mm distance. Industrial fieldbus interfaces integrate live ΔE tracking directly into factory DCS and PLC architectures.
Selection parameters: stand-off distance, line web velocity, communication protocols (RS-485, Modbus, TCP/IP), and protective air purge kits.
FS Series Hyperspectral Imaging Cameras & VNIR/SWIR Spectral Systems
High-throughput hyperspectral imaging systems from CHNSpec combine precision transmission diffraction gratings with Peltier-cooled CMOS and InGaAs focal plane arrays.
Spanning VNIR (400–1000 nm) and SWIR (900–1700 nm) with spectral resolution up to 1.5 nm across hundreds of channels, FS cameras empower real-time polymer identification, mineral sorting, agricultural quality screening, and solar cell luminescence inspection.
Selection parameters: spectral range (VNIR/SWIR), spatial frame rate, GigE/CameraLink interfaces, and uniform illumination rigs.
Factory-grade calibration standards and sampling accessories essential for sustaining peak photometric accuracy on CHNSpec spectrophotometers and haze meters.
Deliveries include serialized white reflectance ceramic tiles, light trap zero cavities, precision fused silica quartz transmission cuvettes (10–50 mm optical paths), modular aperture rings, and stabilized DC power adapters for round-the-clock lab productivity.
Selection parameters: instrument serial model, aperture plate diameter, cuvette optical path length, and calibration tile certification.
Technical Parameters for CHNSpec Equipment Selection
Material consistency (solid opaque sheets, powders, transparent films, solutions), optical geometry (D/8, 45/0, multi-angle gloss 20°/60°/85°), target metrics (CIE Lab coordinates, haze percentage, total transmittance Tt, gloss units GU), auto-calibration dock requirements, and factory PLC communication bus protocols.
We deliver serialized certified white reflectance ceramic tiles, light trap zero cavities, fused quartz transmission liquid cells, modular measurement apertures, and stabilized pulsed light source assemblies sourced directly from original manufacturing records.
Optical Geometry D/8 & Dual Measurement Modes SCI/SCE in Spectrophotometers
CHNSpec DS and CS spectrophotometer platforms employ true D/8 diffuse illumination integrating sphere geometry with an 8-degree viewing angle in strict compliance with CIE Publication No. 15 recommendations and ISO standards.
The interior sphere cavity features ultra-pure barium sulfate BaSO4 diffuse coating delivering uniform illumination across samples regardless of surface roughness or microtexture.
Systems support both SCI (Specular Component Included) and SCE (Specular Component Excluded) scanning modes, isolating bulk pigmentation color formulations from surface specular gloss effects.
Dual Optical Path Differential Spectrum Engine with Nanoscale Gratings
Exceptional photometric stability across CHNSpec systems relies on an advanced dual-beam differential spectrum engine.
During acquisition, optical radiation splits into twin optical paths: the primary beam probes sample surface reflectance while an internal monitoring beam continuously calibrates the photodetector against internal reference standards.
Standardized Haze & Luminous Transmittance Testing under ASTM D1003
CHNSpec TH-100, TH-09, and CS-700 haze testers quantify luminous clarity and light scattering across clear plastics, architectural glass, touch panels, and liquid reagents. Testing strictly adheres to ASTM D1003 (Procedures A and B), ASTM D1044, ISO 13468-1, and ISO 14782 standards.
Instruments utilize certified CIE Illuminant C and Illuminant A standard illumination sources.
The open-sided measurement compartment accepts oversized continuous sheets horizontally or vertically without edge trimming, while optical liquid transmission fixtures with 10 to 50 mm pathlengths facilitate rapid chemical solvent inspection.
Tri-Angle Specular Gloss Measurement Technology 20°/60°/85° in CS-380 Series
Specular gloss evaluation across paints, powder coatings, and polymeric surfaces follows ISO 2813 and ASTM D523 requirements. CHNSpec CS-380 SE tri-angle glossmeters incorporate three discrete optical emitter-detector channels configured at 20, 60, and 85 degrees relative to surface normal.
The 60-degree channel provides universal benchmarking across 10 to 70 GU semi-gloss targets. When samples exceed 70 GU, the 20-degree high-gloss channel provides heightened resolution, whereas matte substrates below 10 GU utilize the 85-degree low-angle sensor. 2 GU.
White Calibration Protocols & Integrating Sphere Preventative Care
Long-term reproducibility in colorimetric quality inspection hinges on the pristine reflectance of calibrated standards. Each CHNSpec unit includes a serialized white calibration tile with factory-mapped absolute spectral reflectance curves.
Daily procedures require zero calibration using the light trap cavity followed by white balance verification on the ceramic standard. In advanced DS-700D and DS-810N series, automatic contact-free calibration occurs whenever the instrument docks into its magnetic base.
Routine care mandates non-abrasive optical cleaning using pure isopropyl alcohol to safeguard sphere coatings.
