Coleman Model 44 provides direct linear absorbance at half the cost of similar spectrophotometers Now, for the first time, you can get direct linear absorbance readout in a spectrophoto­meter in the low price range. The new COLEMAN Model 44 UV-Visible-NIR Meter Spectrophotometer provides the easy, precise readout formerly available only in instruments costing twice as much. It offers a wavelength range of 325 to 825 nm. Linear absorbance readings and linear recorder output eliminate the inconvenience of working with logarithmic scales or charts; save time for the analyst; reduce the possibility of visual errors. Results are shown clearly on the large, 7" wide meter scale. Because the scale is linear, all parts of the meter—even the high absorbance range— are easy to read. Stable meter reading assures fast, accurate readout. Built-in conversion circuit permits instant switching from A to

%T, and vice versa. For new speed and ease in sample handling,

Model 44 can be used with the new Autofill™ Cell Assembly—permits you to introduce a sample, read, flush out, and insert the next sample in seconds. Model 44 carries on the Coleman tradition of low-cost, high-precision, easy-to-use spectrophotometers. This rugged, compact, solid-state instrument is ideal for industrial research, quality control, school laboratories, water quality tests, air pollution measurement, analytical determinations of impurities or trace elements in iron, steel, aluminum or copper; and for testing electro­plating equipment.
