Dual-Channel Flame Photometer

Dual channel mode cuts measuring time in half¡ªobtain Na+ and K+ results simultaneously
Built-in control functions ensure reproducible and reliable results
Send results to a computer or printer with built-in RS-232 interface Specifications
This digital unit offers improved analytical performance over single-channel flame photometers in the measurement of sodium, potassium, and lithium ions. Features include automatic ignition sequence, lithium internal standard, monitoring and control software, dual-channel display, and independent calibration of each channel.
The lithium internal standard signal reduces fluctuation in flame conditions, drift, and dilution errors¡ªensures reproducible results and precise measurements. The fully automatic ignition and flame optimization sequences reduce set up and calibration time. An automatic gas shutoff mechanism activates if the flame is accidentally extinguished. The monitoring and control software make operation simple and allow measurements only after blanking and calibration.
This photometer can operate in continuous or peak mode. In peak mode, transmit results to a printer or computer with the built-in RS-232 interface. Specifications
