5. Display - displays measurements, mode options and battery indicator.
6. LED Indicator Light - indicates when to dip instrument in solution, when measurement is in progress, and when to remove instrument from solution.
7. Electrodes - measure electric current of solution.
8. Cell - contains flux field in defined area for accurate current measurement.
9. Scoop - contains sample solution for measurement when sampling from a vertical stream. To use, slide the open end of the scoop over the bottom of the pen until the neck of the scoop is flush with the top of the cell. Hold pen with scoop end under stream. Rinse and fill with sample solution 3 times. Fill with solution again, then take measurement. We recommend you recalibrate the pen using the scoop to retain accuracy of ±1%.
