Thermo Finnigan Surveyor PDA Detector CLEARANCE! As-Is

Thermo Finnigan Surveyor PDA Detector

** Buyer can expect a working machine and 30-day warranty. Unit has slight wear from normal use. See photos for details.

The Surveyor PDA Detector is a full-featured, time-programmable, photodiode array detector. Detection can be carried out in the full ultraviolet-visible range from 190 to 800 nm. Data can be taken in this range at a rate of up to 20 Hz with 20-bit digital conversion. The Surveyor PDA Detector is a bench-top unit for inclusion in the
Surveyor liquid chromatography system. It is controlled remotely over an
Ethernet communication link from a PC using Chrom Quest or Xcalibur
software. The detector consists of a dual-light source, an optical bench, a
photodiode array, a low voltage power supply, several printed circuit boards
(PCBs), and four status LEDs.
