Measuring Instruments
CM-5
Spectrophotometer (Top port)
Versatile standalone top-port instrument with innovative easy operation
Keyboard and large LCD with wizard guidance enable easy operation for anyone without the need for a separate computer. Full range of functions for reflectance and transmittance measurements.
New Features
- Portuguese language display added
- Spectral absorbance measurements
- Mini Petri Dish (Optional accessory)
Features
Easy, Standalone Operation
1-2-3 measurements
1. Switch power on.
2. Position sample.
3. Press MEAS.
Large color LCD
The large color LCD is easy to read and can display data not only numerically but also on spectral graphs and color plots as well as showing PASS/FAIL judgments.
Spectral graph
L*a*b* color plot
Wizard for on-screen operation guidance
The wizard function provides on-screen guidance for users to help them make instrument settings.
USB storage of settings and data
To avoid confusion when several people use the same CM-5, users can store their settings on a USB memory stick, and then read these settings back into the CM-5 when they use the instrument. Target and measurement data can also be saved to the USB memory stick and taken with the user for later analysis.
Automatic calibration
White calibration (for reflectance measurements) and 100% calibration (for transmittance measurements of solids*) can be performed automatically when the instrument is switched on.
- *
- Automatic 100% calibration for liquid transmittance measurements using cells is not possible.
User-settable index equations
Users can also input their own index equations to enable measurement and color control based on their own company or industry calculations.
8 languages
Displays can be shown in any of 8 languages: English, Japanese, German, French, Italian, Spanish, Simplified Chinese, and now Portuguese.
Reflectance color measurements
Top-port design
The top-port design of the CM-5 makes sample positioning easy. There's no need to clamp the sample in place, and no worries about samples shifting position
Three measuring areas
Three sizes of target masks are available to adapt to different sample sizes: Ø 30mm (standard), Ø 8mm (optional), and Ø 3mm (optional)
Measures a variety of samples
Solid samples can be placed on top.
Small samples (optional Ø 3mm target mask)
Chunky samples (optional Petri dish)
Pastes (optional Petri dish)
Pellet samples (optional Petri dish)
Tiny amounts of costly samples (optional mini Petri dish)
Mini and Standard Petri Dishes (Optional accessories)
Petri Dishes enable measurements of granules, powders, pastes, and opaque liquids, and the automatic calibration function of the CM-5 can be used with both the Standard and Mini Petri Dishes The new Mini Petri Dish (Ø16 mm outside diameter; Ø3 mm measurement area) enables measurements using much smaller sample amounts (approximately 1/20 of the amount required when using the Standard Petri Dish), making it ideal for costly samples such as rare-earth metals, organic EL materials, pharmaceuticals,etc.
Optional Petri Dish
Optional Mini Petri Dish
Transmittance color measurements
Large transmittance chamber
Sliding open the CM-5 reveals a large transmittance chamber with no sides, so even large sample sheets can be inserted and measured. Transmittance samples up to 60mm thick can be measured.
Liquid measurements using cells
Liquids can be measured using cells (optional). Cells with optical path lengths of 2mm, 10mm, and 20mm are available for measuring liquids of different densities. In addition, 10mm-wide commercial cells can also be used.
Spectral absorbance measurements
Spectral absorbance can now be measured and displayed numerically or graphically even when the CM-5 is used without being connected to a computer, enabling evaluation of spectral absorbance for checking absorbance wavelengths, evaluating colorants, calculating K/S, determining components, etc.
Internal calibration curves for standard chemical/pharmaceutical indices
The CM-5 has internal calibration curves for several of the standard color indices used in the chemical and pharmaceutical fields: Gardner, Hazen/APHA, Iodine Color Number, European Pharmacopoeia, and US Pharmacopeia, so measurements based on these indices can be taken easily by anyone.
- *
- Since index calibration curves were measured using the optional 10mm-Wide Cell Measurement Set CM-A207 and commercially available 10mm-wide cells with 10mm optical path length, it is recommended that index measurements also be taken using the same optional accessories.
Principal Applications
