ELICO’s SL- 194, AAS Spectrophotometer is fully automated and delivers a new level of flexibility and simplicity. It can work as standalone mode for routine analysis and can also be fully PC Controlled. The selected element lamp is automatically aligned in the built-in 6/8 lamp turret which automatically recognizes coded HCL lamps and loads their operating parameters. The instrument provides many features in terms of performance and saftey never before available on low-cost AAS
