Introduction
Intended use of SPEKOL 2000
1 Introduction
1.1 Intended use of SPEKOL 2000
The SPEKOL®2000 is a compact, computer-controlled two-beam spectral photometer to
measure the transmission, extinction, concentration and energy level of liquid samples. It
is designed to perform measurement within the spectral range of 190 nm to 1100 nm. Its
optical system ensures genuine real-time operation, so even variations in the absorption
of a reference sample can be compensated while measurement is going on. Combined
with powerful WinASPECT®software, the SPEKOL®2000 is particularly suited for
applications in clinical, biochemical, chemical or environmental laboratories, as well as
other sectors of routine analytics, research, development and quality control.
This User Manual contains a detailed description of the SPEKOL®2000, its
specifications, available accessory items and useful advice on maintenance.
Once the photometer has been carefully unpacked, you should visually check for
completeness of delivery against the packing list. Likewise, one should perform an
inspection for proper condition. On noticing any kind of non-conformity, you are advised
to immediately contact our Representative Office or our Service.
