Product Overview

• The 420C (475 42 000) is delivered as standard with a mixed calibration concentrate containing 140.0, 5.00 and 1.50 mmol/l of Na, K and Li.
• The M420 Industrial (475 42 100) is delivered as standard with individual 1000ppm calibration concentrates for Na, K and Li.

Dual Channel operation, allows both Sodium and Potassium to be calibrated, measured and displayed simultaneously. The Model 420 Flame Photometer retains many of the Model 410’s attributes: ease of use, ease of maintenance and stable flame design and is enhanced with auto flame optimisation, internal standard referencing and on-board firmware to achieve significant improvement in sample throughput and precision. The time taken to set up and calibrate the instrument is much reduced; achieved by automatic ignition and optimisation of the flame conditions. The analytical performance is improved using a Lithium Internal Reference signal which compensates for fluctuation in flame conditions. The internal reference feature (Reference Mode) can be turned off if required. Readings on both channels are linear over the working range of the Model 420 Flame Photometer. There are several monitoring and control functions included in the firmware; thus, measurements can only be made after blanking and calibration.
