Description

WA2081 Atomic Absorption Spectrometer

.Introduction
WA2081has high precision, humanized designation to fully meet the different requirements of users. Users can choose graphite furnace control, automatic injector, hydride generator and so on.

.Features
1. There are four-lamps position and six-lamps position for option, and the preheat lamp number can be customized, which can short the waiting time of operating process.
2. The lamps have the functions of self-optimized, and three-dimensional self-adjustment to maximize the energy. 
3. The elements have the functions of negative high-voltage self-memory, wavelength scanning, lamps self-optimization and energy optimization with one key step. 
4. It is convenient for the testing results to be exported by various formats and operated by office software. 
5. This system can be remote controlled so that its problems can be solved in time with remote control technique.
6. Hydride generator can be used.
7. Automatic ignition system can be used.
