Description

High-precision spectrophotometer with ISO compliant gloss sensor and stability check

The CM-36dGV Spectrophotometer is a high-precision and high-reliability bench-top instrument capable to measure colour either in reflectance or transmittance and thus offering a wide range of applications such as Plastics, Paints, Ceramics, Chemicals etc.

For the first time ever, Konica Minolta Sensing integrates an ISO 2813 compliant 60° gloss sensor inside a benchtop spectrophotometer, to simultaneously measure Color and Gloss values at the same spot at the same time. As both value sets are reported together, not only are manual errors reduced but also valuable working time as well as money for additional equipment saved.

The CM-36dGV utilizes the patented and proven Numerical UV Control (NUVC), the unsurpassed technology for UV adjustments when measuring samples containing optical brighteners such as pulp, paper, textiles or chemicals.

Several further features for your convenience, like status LEDs or camera preview for sample positioning and reporting complete the picture.

Konica Minolta’s patented technologies assure highest accuracy and repeatability levels unseen before in this price class. These technologies combined with superior reliability due to our latest innovative feature “Wavelength Analysis and Adjustment” give our customers the possibility to check and adjust the CM-36dGV during calibration, to always assure the instrument is in perfect condition. 

Features

Efficient sample presentation

Four screw threads and linear guidelines in the front plate enable the operator to create custom jigs to accurately position samples – maximising the repeatability and speed of the measurement process.

Camera previewer for accurate sample positioning

The integrated camera viewer provides a clear preview of the sample for precise targeting and control the area to be measured. The software can capture images of the area that is measured to provide detailed and concise reporting.

Reflectance and Transmittance measurements, horizontal or top-port

The CM-36dGV can measure solid or liquid samples in reflectance or transmission mode, horizontally or upside down. This offers great flexibility for various samples ranging from opaque to translucent and transparent.
The large, open sided transmission chamber can be used to measure transparent or translucent samples of any size with ease. The transmission chamber lid features a lift-and-turn lock to prevent accidental opening of the device and locks the chamber when used upside down to measure e.g. powdery material in round cuvettes.

Numerical UV Control for Accurate Measurements of Fluorescent Materials

Accurate measurement of materials such as paper or cloth treated with optical brighteners (OBA) requires precise control of the UV component. The patented Numerical UV Control method (familiar to customers who used the CM-3600A) provides UV control by using proprietary calculations to combine the results from flashes of two xenon lamps: one with full UV energy, the other with UV energy removed by a UV-cutoff filter (either 400 nm or 420 nm). This method eliminates the need for lengthy filter position adjustment processes, and enables UV adjustment by Whiteness Index, Tint, Brightness, or UV profile.

Easy to read LED indicator panel with measurement button

The LED indicator panel displays current measurement settings at a glance. In addition, the measurement button in the panel allows to measure samples remotely.

Measurement Areas to match your samples

The CM-36dGV offers four different apertures with Ø 4.0, 8.0, 16.0 and 25.4 mm to provide a suitable measurement size for any sample.

“Wavelength Analysis & Adjustment” – (WAA)

“Analyze – Adjust – Activate” – Konica Minolta’s patented technology checks and adjusts possible wavelength shift during each instrument calibration. This procedure assures unsurpassed long-term measurement stability and can keep measurements stable even for changes in temperature or environment conditions over time.

WAA allows the operator to easily distinguish whether the instrument itself is the cause of measurement differences, reducing troubleshooting time and providing improved certainty within supply chains.
