Handheld Spectrophotometer

Model: ST-302

ST-302 color spectrophotometer features customized aperture, optional is 8mm/4mm/1×3mm. High accuracy 0.04 lets Stalwart spectrophotometer better suitable for color matching system for better color measurement and color formula use.

Multi-illuminants, Customizable Aperture, SCI&SCE, Bluetooth Communication, High Precision. Comply with CIE No.15, ISO7724/1,ASTM E1164,DIN5033 Teil7, ST-302 color spectrophotometer features only 8mm single aperture. Both SCI and SCE mode makes it widely use in many applications. It has high accuracy 0.06 based on white calibration plate measured 30 times at 5 seconds intervals after white calibration was performed.
