More About this Item

This enhanced four-element flame photometer offers the same great features found on our dual-channel flame photometer, plus a calcium channel and direct measurement of Ca+ with potassium, which are two vital elements for soil analysis. Unit allows you to measure calcium in combination with sodium, and also with lithium without an internal standard.
Use this flame photometer as a detector in combination with multi-channel analyzers from Bran & Luebbe, Skalar, and Lachat. This system includes its own protocols for calibration, and features a special mode allowing you to set up the flame photometer within these protocols. User-selectable signal averaging is designed into the system allowing you to use these protocols along with analog output. Features include automatic ignition sequence, lithium internal standard, monitoring and control software, dual-channel display, and independent calibration of each channel. An automatic gas shutoff mechanism activates if the flame is accidentally extinguished, or if air pressure drops.
Order optional Automatic Dilutor 02657-00 which accurately dilutes your samples and standards; order optional Autosampler 02657-25 for a fully automatic analysis solution for your longer sampling runs.
