The SP-830 Spectrophotometer has a continuous spectral range of 330-999 nm accommodates many photometric analyses performed in clinical and industrial laboratories. This spectrophotometer uses a plane diffraction grating monochromator. The large versatile sample fits both round (12-13 mm diameter) and standard square cuvettes. Possible applications include phosphorus analysis, iron analysis, chlorophyll analysis, turbidity as well as color and clarity testing. Analog output to interface the instrument to a data processor, strip chart recorder, or other external analog device. Serial RS-232C and/or parallel centronics printer port for interfacing spectrophotometer with a computer or external printer. User-friendly software allows even inexperienced personnel to operate the unit without touching a manual. Fan cooling ensures temperature stability. 8 nm spectral bandwidth. Easy-to-read wavelength selector is graduated in 1nm increments. Auto-zero function pushbutton setting of 100% TRANS and 0.000 ABS at one touch. Five switchable built-in second-order stray light filters eliminate the inconvenience of exchanging filters. Easy-to-read 3.5 digit LED.
