Automatic Saybolt colorimeter tester Observer Angle 2°/10° 100mm optical path ASTM D156

SH810B fully automatic colorimeter features microprocessor-controlled touch screen operation, suitable for both laboratory and field use. It includes factory calibration and user-defined calibration functions, with a uniquely designed sample cell for easy measurement and maintenance.

Saybolt (ASTM D156, GB/T 3555, NF M 07-003)

The platinum-cobalt colorimeter employs a D/0 measurement structure, integrating full-bandwidth light sources, single-grating optical path spectrometry, and ETC real-time calibration technologies, achieving a resolution of 0.0001, a transmittance standard deviation within 0.08%, and a color difference value of ΔE*ab 0.015.

The platinum-cobalt color is expressed in Hazen units, where one unit corresponds to the color of a solution containing 1 milligram of platinum as chloroplatinate and 2 milligrams of cobalt chloride hexahydrate per liter. The typical range generally falls between 1 and 500 Hazen units. This method is suitable for determining the color of transparent or slightly hazy liquid chemical products that are close to the platinum-cobalt reference color, which is usually brownish-yellow in hue.

Gardner Color Scale: Standard color values are obtained by mixing solutions of cobalt chloride, ferric chloride, and potassium chloroplatinate in varying proportions, typically ranging from 1 to 18. It is suitable for colors that are darker yellow or more brownish than the platinum-cobalt color scale.

Instrument features:

● Utilizes intelligent zero-point calibration to ensure precise measurement with △E*ab≤0.01

● Dedicated paraffin cuvettes, 100mm cuvettes

● Fast measurement speed, with a single measurement taking only 1.5 seconds

● Constant temperature sample bath: Room temperature to 90°C, ensuring sample fluidity

● Heating module: PTC heating module

● 7-inch touchscreen offers a user-friendly interface, with the instrument capable of storing over 100,000 data entries

● Measurable, including colorimetric indices such as platinum-cobalt, Gardner, Saybolt, and others

● The minimum liquid addition is reduced to 1ml, with standard 10mm and 50mm cuvettes, and 33mm cuvettes (optional)

● The instrument measures wavelengths in the range of 360–780 nm, exceeding the visible spectrum of the human eye and extending the measurement range.
