What is the purpose of the solid secondary standard?
The solid secondary standard is designed for recalibration in place of primary standards and to check for instrument performance and drift. It is very stable and does not require special storage conditions. · What is the concentration of the solid secondary standard? There is no exact concentration for the solid secondary standard. It is a relative concentration for both Chlorophyll a and Rhodamine WT. You can easily adjust the fluorescence signal of the solid standard and use it as a reference value for future calibrations as well as check for electronic drift. · What is the power consumption if using internal data logging? When using internal data logging, the total power consumption is dependant on the sampling rate set by the user. If the sampling rate is set to an interval longer than 1 reading every 5 seconds, the unit will power down into sleep mode (60mA). The instrument will consume 60mA when logging data. · How long can the SCUFA® stay submerged with anti-fouling screens? The
