Specification :

The PFP7/ C is a low temperature, single channel flame photometer
that is specifically designed for use in clinical applications for the
determination of sodium, potassium and lithium. The in-built
lineariser circuitry of the PFP7/ C enables readings of both sodium
and potassium to be displayed directly in mmol/ l. The series 7 diluter
is available for use with the PFP7/ C to enable serum samples to be
diluted efficiently and accurately to the required ratios.
