    Description

    An innovative Benchtop Spectrophotometer with user friendly features and a large onboard display. The CM-5 is a benchtop spectro with a top facing port meaning easy changes for solid samples and samples in petri dishes. It can also measure the colour of liquid and transparent samples.

    The CM-5 is a very versatile bench-top spectrophotometer to measure the colour of solid, pasty granular and liquid samples either in reflectance or transmittance. The top-port concept, offering various aperture sizes, allows measurement of almost any kind of samples. The CM-5 is thus the perfect all-rounder laboratory instrument for applications such as Flavours & Fragrances, Foods, Chemicals, Pharmaceuticals and Plastics.

    The CM-5 can work stand alone thanks to the large colour screen and extensive firmware offering all major colorimetric systems including industry specific indices to measure transparent liquids such as Gardner, Hazen/APHA, Iodine, European and US Pharmacopoeia. In combination with the optional software SpectraMagic NX, Haze and many more indices are available.

    Very intuitive routine work is guaranteed by features such as automatic calibration, Operation Wizard and support in seven languages.

    Features

    Versatility for a wide range of Applications

    Thanks to the unique concept and a wide range of special accessories, the CM-5 can handle almost any kind of samples in solid, granule, pasty or liquid form.

    Aperture size from 3 – 30 mm, different Petri-dishes, different cell paths and a large transmittance chamber offer a unique flexibility.

    Versatility

    Large colour LCD

    The large colour LCD is easy to read and can display measurement data numerically and graphically or even just as PASS/FAIL judgments.

    LCD

    Wizard for on-screen operation guidance

    The wizard function show intuitive on-screen guidance for users for instrument set-up.

    Wizard

    USB storage of settings and data

    Individual user set-ups as well as target and measurement data can be easily stored on USB memory stick to allow multi-user capability.
