Description

 

Use Klett™ Colorimeters for Colormetric and Turbidimetric Determinations Including Color, Concentration, Haze and Density Measurements and Microbiology Growth Curves


Rugged construction for long service life

Klett scale is longer than many other photoelectric scales allowing greater graduation spacing for easier and more accurate readings

Repeatable results with accuracy to 0.33% on the full scale

Accessory filters allow measurement over complete visual range

Measurements for both color and turbidity are possible

Fully compensated and balanced electrical circuits do not require storage batteries or current regulators

Available as 115 or 220V for use worldwide


These photometric colorimeters use specific light filters to give readings on a unique Klett™ scale. The readings are directly proportional to the concentration or optical density of a solution in accordance with Beers Law. Two matched photocells and a suspension galvanometer give the instrument a broad range of measurement; it is light and ambient temperature independent. A fully compensated and carefully balanced electrical circuit provides accuracy and consistency of readings. The precision galvanometer has an illuminated logarithmic scale, graduated from 1 to 1000 Klett™ and the scale is graduated in units proportional to the optical density. Repeatability is ±0.33% of the full scale. Two models, Clinical and Industrial are available. Each comes complete with detailed instructions, standards and guides for a wide range of tests.



The Clinical Model (800 series) uses standard 14.25 x 125mm test tubes. Calibrated or uncalibrated tubes are available and micro test tubes can be used for samples as small as 2.5ml.

T37012-0001 Model 800-3, 220VAC



The Industrial Model (900 series) accepts rectangular solution cells, which can be used in either of two directions. Measurements can then be taken at depths of 10mm, 20mm, or 40mm. A reduction plate is available to minimize solution depth to 2.5mm. An adapter is available that permits the use of test tubes.

T37013-0000 Model 900-3, 110VAC

T37013-0001 Model 900-3, 220VAC



Both models are supplied with the two most commonly used filters, blue for 400-450nm and green for 520-580nm. Additional filters are available to permit measurements over the complete visual range.
