Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 5890 II #9220910 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 5890 II spectrophotometer is a microprocessor controlled, highly accurate, and reliable analytical instrument used for measuring light intensities in the UV-visible range of the electromagnetic spectrum. It is a double-beam spectrophotometer that is equipped with a tungsten-halogen lamp for providing illumination. It can be programmed and operated with a PC workstation, as well as manually with the integral knobs and switches. HP 5890 II features an optical path consisting of two separate paths: the sample and reference channels. The sample path measures the light transmission of the sample being tested, while the reference path measures the intensity of the light source. This setup allows the spectrophotometer to make more accurate measurements than a single-beam spectrophotometer with only one optical path. The two channels are aligned using the photocollimator, which ensures precise optics for excellent performance. AGILENT 5890 II has two detectors: a photomultiplier tube (PMT) that measures light output in the visible region from 400-800nm, and a two-channel, extended range CCD (Charge Coupled Device) that can detect light from 190- extends the range down to narrow. The PMT has superior sensitivity and offers excellent linearity and stability, making it ideal for applications such as reflectance and absorbance measurement, while the CCD has improved detection of light at even lower wavelengths, allowing for improved quantitation of UV absorbing compounds and dyes. HEWLETT-PACKARD 5890 II incorporates a variety of features including the ability to be remotely controlled via PC and software, with a range of possible settings, a variety of filters and polarizers which allow for discriminative light measurements, auto-calibration settings with memory, self-diagnostic functions, optimized software for calibration and lamp exchange, buffer solutions to control pH values, and superior customer support. In conclusion, 5890 II spectrophotometer is a reliable, high-performance, and versatile instrument featuring advanced optical designs, superior sensitivity, and extended range. The spectrophotometer is suitable for a wide range of applications, from general photometric measurements to those involving more specialized measurements of UV absorbing substances.
