• Covers a spectral range of 330 to 999 nm with an 8 nm spectral bandwidth for high resolution and accuracy
• “Auto-Zero” function automatically sets your blank to 100%T or .000A

Microprocessor controlled spectrophotometers are available in three models to meet the needs of industrial, clinical or research labs. All models feature a plane diffraction grating monochromator and five built-in, switchable stray light filters. Versatile sample compartment fits both round tubes (12 to 13 mm Dia.) and standard square cuvettes (12.5 x 12.5 x 45 mm). Offers analog output for connection to a recorder, and RS-232C interface for connection to a computer. User-friendly software makes operation easy.

Model 22249A is economical and reliable with manual wavelength setting and filter selection. 22249B offers concentration mode, to read concentration directly from the unit with built-in calibration standards. Model 22249C offers digital wavelength selection, automatic filter selection, and a 5 nm spectral bandwidth for even higher resolution.
