Spectro UV-VIS RS
Model UV-2502


Spectro UV-2502 is and advanced generation improved Spectro UV-2500 with a newer bandwidth of 2nm.

Spectro UV-
2502 is a traditional analytical device used in conventional laboratories.  This spectrophotometer delivers enhanced user-friendliness, precision and accuracy resulting in time and cost savings, as well as unprecedented confidence in test results. Model UV-2502 works in the ultraviolet and visible range of 190-1100 nm and has a New and Improved 2nm. Bandwidth!.  Model UV-2502 spectrophotometer offers high performance and reliability, which can be used in various applications. Spectrophotometer Model UV-2502 can be used extensively for qualitative and quantitative analysis in such fields as clinical analysis, petro-chemistry laboratories, chemistry and biochemistry laboratories, as well as in quality control departments, i.e. environmental control, water management, food processing, and agriculture.

Spectro UV-Vis RS (Model UV-2502) is equipped with the RS-232C interface and port which link the spectrophotometer and the PC using the UV-VIS software. Model UV-2502 can be linked to a computer, which is compatible with Windows Platforms, and a printer to display the photometric and spectral data on the PC monitor.

Spectro UV-Vis RS (Model UV-2502) utilizes a new optical system design and is microcomputer controlled.  This instrument has soft keys for ease of use and may utilize 13 mm test tube.  Model UV-2502 has excellent baseline stability and high resolution. 

Spectro UV-Vis RS (Model UV-2502) consists of a light source (Tungsten Halogen and Deuterium lamp), monochromator, Silicon photodiode, logarithmic amplifier, digital volt meter, D.C. stabilizer, and microprocessor.  This new generation instrument is equipped with a microprocessor to automatically adjust 100 % T and Zero ABS, Factor, and Concentration. Spectro UV-VIS
2502 operates with a single beam system and 1200 line grating mirror.  Model UV-2502 has a four digit display for automatic calculation and direct readout of (T)ransmittance, (A)bsorbption, and (C)oncentration. 

This Spectro can be used by itself or linked to a PC.

Labomed, Inc. is certified by ISO 9001-2000, has CE Conformity and is FDA Licensed.
