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. Built-in linearizing software allows sodium measurement up to 40 ppm.
Obtain Na+ and K+ results simultaneously. The lithium internal standard signal reduces fluctuation in flame conditions, drift, and dilution errors—ensures 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. Monitoring and control software allow measurements only after blanking and calibration.
