The Spectrophotometer CM-36dG is a horizontal format spectrophotometer that offers simultaneous color and gloss measurements and UV adjustment function. It is ideal for a wide range of applications such as plastics, paints, chemicals, etc.

Spectrophotometer CM-36dG

The Spectrophotometer CM-36dG, successor to the Spectrophotometer CM-3600A, is a highly accurate and repeatable benchtop color measurement instrument that comes with advanced functions for today’s measurement needs.

The CM-36dG is capable of measuring color in either reflectance or transmittance. It also comes with a 60° gloss sensor (ISO 2813 compliant), enabling the simultaneous measurement of color and gloss that improves work efficiency.

Equipped with the patented Numerical UV Control (NUVC), the CM-36dG offers precise and easy UV adjustments when measuring samples that contain optical brighteners (OBA) such as paper and textiles.

With a tight inter-instrument agreement (IIA) and repeatability of ΔE*ab< 0.12 and σ∆E*ab < 0.02, respectively, the CM-36dG can ensure the measurement and its data are communicated within the supply chain, from suppliers to finished product maker, consistently.

The CM-36dG is design with enhanced useability. It features an easy-to-read status panel, with the measuring button located on it, that displays the measurement status and condition settings to minimize operator error and improve work efficiency. The sample viewing function, utilizing an integrated camera, is also available to ensure accurate and easy positioning of the measurement sample.

With a large and open-sided transmission chamber, the CM-36dG can easily measure transparent or translucent samples of any size. With a flat-back design, the orientation of CM-36dG can be repositioned to take measurements vertically (top-port concept). The front plate of the CM-36dG comes with four screw holes that allow the easy installation of custom adapter/sample holders. The CM-36dG also comes with four different aperture sizes (Ø 4.0 mm, 8.0 mm, 16.0 mm, and 25.4 mm), offering versatility to different measurement needs.

The CM-36dG offers high stability and reliability with its optional WAA (Wavelength Analysis & Adjustment) function. This innovative function analyzes and adjusts any wavelength shift during each calibration, ensuring the instrument and its measurement remain stable and reliable over time.
