It was 20 years ago though when he spotted the clinical potential of the intuitive colorimeter
With 8 different visible illuminations and 1 ultraviolet illumination, the RM200QC is able to more accurately define the location of a color in color space than traditional colorimeters
that typically have only three illuminations of red, green and blue light.
can be utilized to find concentrations of substances, since the amount of light that is absorbed or transmitted depends on properties of the solution, including the concentration of target analytes in it.
have color filters that estimated the spectral function of the standards observer's eye and ate generally designed to measure color in X;Y;Z tristimulus terms or in CIE L*a*b* values.
with laboratory grade, dual LCD/CRT measurement capability.
With its seven-filter color sensor, it more closely matches the human eye response than conventional colorimeters
, resulting in a highly accurate calibration, according to Pantone.
Advantages of colorimeters
are: (1) they are more than adequate for many applications, (2) they generally require less service compared to the more complex and expensive spectrophotometers.
can be calibrated against these sources with minimal errors, on the order of 0.
Many common measuring instruments contain RS-232 output, including gages, scales, laboratory instruments, colorimeters
, flow meters, robotics, some sensors and more.
New in 2000 is the Product Supplement section which features our extensive line of AQUAfast(r)II Colorimeters
The Tintometer Ltd of The Colour Laboratory, Waterloo Road, Salisbury, Wiltshire, tel:0172 232 7242 tell us they have brought out two automatic colorimeters
for the objective colour measurement of products such as oils, fats and syrups.
The principles behind both colorimeters
and spectrophotometers are simple: A calibrated light source shines onto or through a solid or opaque, translucent or transparent liquid test sample, and then the meters measure the light reflected from or transmitted through the sample.
Colorimetric assays require a large sample volume, running of known standards, use of colorimeters
, plotting of standard curves and so forth.
Radiant Zemax, a leading provider of light and color test and measurement systems and optical and illumination design software, today unveiled its next-generation ProMetric([R]) G family of imaging colorimeters
, the latest in the company's industry-leading line of imaging colorimeters
