Digital Colorimeter

The Digital Colorimeter from Hangzhou CHN spec Technology., Ltd. is a handheld instrument designed for spectral reflectance measurement in the 400 to 700 nm range, with a d8 geometry and integrated sphere. It reports values in CIE L*a*b*, CIE XYZ, and ΔE*ab formats, with a repeatability of ±0.1 ΔE*ab under standard lighting conditions. The device uses a tungsten halogen light source and a silicon photodiode array, calibrated against NIST-traceable standards. Its measurement aperture is 8 mm, and it supports both specular component included and excluded modes.

The instrument is built with an ABS housing and operates on a rechargeable lithium-ion battery with 8 hours of continuous use. The display is a 2.4-inch TFT touchscreen with adjustable brightness. Standard accessories include a calibration white tile, a black trap, and a protective carrying case. While the listing does not confirm ISO or CE certification, these are common industry requirements for laboratory-grade colorimeters in the EU and North America. The device is designed for environments requiring consistent color assessment, such as textile dye lots, paint batch matching, and food product grading.

Buyers in the textile, paint, plastics, and food industries use this device for quality control during production and incoming inspection. It is typically ordered in quantities of 1 to 5 units for lab use, though bulk purchases are common for multi-site manufacturers. Trade terms are typically FOB Hangzhou or CIF port of destination, with lead times of 7 to 14 days after payment confirmation. Packaging is in foam-lined cartons with internal humidity control. Buyers should confirm the calibration certificate and software version prior to shipment.
