 Model FPH is a micro-controller based
instrument designed to provide automation in operation,
measurements and end-result presentation. It does the estimation
of Sodium (Na), Potassium (K), Lithium (Li), and Calcium (Ca) in
single aspiration of a sample. For user’s convenience, the
instrument offers two measuring modes: W Low Concentration and
(ii) High Concentration. There is facility of curve fitting
correction for non-linear emission characteristics of element,
at higher concentration, store (save) Setup for frequently used,
measurement (in a battery-backup memory) and the same can be
recalled whenever required with a press of a button. Also
re-standardization using single standard to minimize the effect
of any unforeseen drift without going for the full
recalibration. 4 Line 20-character LCD readout provides easy
user interface & presentation of results. A Centronics printer
port provides print out of results on EPSON compatible Dot
Matrix Printer; supply of Printer is an optional. |
