YSI 600DW-B Sonde - Manual (Page 278)

Quick Start Guide to Drinking Water Studies Appendix F
NOTE CAREFULLY: Users who are accustomed to installing a Teflon membrane on a YSI dissolved
oxygen sensor should note that the methods recommended for the Teflon installation are not likely to work
well for the free chlorine membrane because this membrane cannot be stretched. Therefore, dissolved
oxygen membrane installation techniques which are outline in the manuals for various YSI instruments,
including standard 6-series sondes utilizing the 6562 Rapid Pulse DO sensor, are NOT RECOMMENDED
for the free chlorine membrane installation.
