Color, Oil & Haze Measuring Instrument

COH 400

COH 400 is a tristimulus-value direct reading type color meter for simultaneous transmittance color and turbidity measurements. By simultaneously measuring color and turbidity, sample’s visual property can be quickly known in one lump, which is now making it possible even to measure such samples as are changing in color and turbidity with passage of time. This model is an innovative instrument that can be used for color and turbidity measurements of potable water, oil, glass, film and resin, etc. as well as for color evaluation of Hazen color number (APHA), Gardner color number, Saybolt color and ASTM color regarding petroleum products.

Features

You can measure color and turbidity simultaneously by this one instrument, and will know sample’s visual property in one lump.

Liquid samples can be measured in the range from low to high density as you can set a cell up to the size of 100mm.

Automatic measurement at arbitrary intervals is possible due to the built-in automatic measuring function, which is very convenient for averaging measurement.

Depending on the purpose of use, 3 different types of this instrument are available: F type for color & haze measurements, C type for color measurement of petroleum products and FC type for measurements of color, haze and color of petroleum products.

In addition to the measurement using the standard attachments, measurement using a test tube is also available (in option).

Using communication software (option), measurement data can be transferred to your personal computer.
