Spectrophotometer

Advantages

 

• Measures reflection with specular component include / specular component excluded (SCE / SCI) and transmission, absorption
• High powered LED-light source with an optimal life span
• Stepless adjustment of the measuring area from 3 to 30mm
• Reproducibility < ΔE 0.01

 

Options: Pay only what is needed!

• Transmission measurement: External sample measurement without dirtying the inner of the device
• Probe-video- / desktop-picture
• Infrared thermometer for measuring the sample temperature

 

Description

With the new developed, high-quality ColorTube, solid and liquid samples can be measured in reflection, absorption and transmission mode. For the measurement of transparent samples, the spectrophotometer is optionally equipped with a third measuring channel. For this purpose, an additional measuring attachment is fitted outside the device.  This flexibility allows the device to measure a wide range of samples from opaque to translucent to transparent.

The ColorTube is characterized by a modern and functional design. Only high-quality components are used for the ColorTube, such as a robust aluminium housing, hardened glass cover and stainless steel components.

The heart of the two-channel system is an integrating sphere with a diameter of 140 mm and two spectrometers for the sample and reference channels. The measuring range is between 400 nm and 700 nm with a spectral scanning of 3.5 nm. The integrated gloss trap allows measurements with and without gloss exclusion. High-performance LED light sources ensure long-term stable measurement results. The UV component can although be set variably. Depending on the type of sample, the measuring surface can be infinitely adjusted from 3 mm to 30 mm.

The device can be connected via USB cable with each Windows PC. Together with the in scope of delivery, extensive quality assurance backup software offers the ColorTube the perfect complete solution to compare and review the values your products.

The measurement of pastes, powders and granules can be done easily with an optionally available glass cuvette. For this, the ColorTube can be brought into a vertical position.
