| Klett-Summerson Photoelectric Colorimeter, Model 800-3 |
|
| This instrument is fully calibrated and comes with a one-year warranty. All of our colorimeters come with a brand new pair of matched photocells. Price includes your choice of any filter we have in stock. These photometric colorimeters use specific light filters to give readings on a unique KlettTM 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 making it light and ambient temperature independent. A fully compensated and carefully balanced electrical circuit provides accuracy and consistency in readings while using simple and rugged equipment. The precision galvanometer has an illuminated logarithmic scale, graduated from 1 to 1000 KlettTM and the scale is graduated in units proportional to the optical density.
