Hewlett Packard 8452A Diode Array Spectrophotometer with 89090A Peltier Temperature Controller

The HP 8452A Diode-Array Spectrophotometer is a single-beam, microprocessor-controlled spectrophotometer. Visible/UV – range of 190 to 820 nm with 2 nm resolution. It is used when speed of measurement is essential. It is faster, more sensitive and some believe it has more precision than a conventional spectrometer due to the photo diode-array detection system.

With its diode array technology, the spectrophotometer is much faster then conventional instruments; with more precision, more sensitivity and more reproducible results.
