Laser safety warnings
The
Zetasizer Nano
optical unit is a
Class 1
laser product and, as such, there is
no exposure to laser radiation in its normal operation. The laser passes through the
cell area but this area is enclosed when the cell is fitted. When the cell is not fitted, a
mechanical laser shutter prevents exposure to laser radiation.
Warning!
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
