DUAL-DPM

The outstanding sensitivity of the photomultiplier DUAL-DPM exceeds the performance of the DUAL-DPD photodiode. Using the DUAL-DPM in conjunction with the DUAL-DB unit, which provides blue modulated for fluorescence excitation, allows reliable measurements of suspensions with chlorophyll concentrations down to 0.5 µg/L. Like the DUAL-DPD photodiode, the DUAL-DPM is mounted on the ED-101US/MD optical compartment right-angled to the DUAL-DB or DUAL-DR head.
