YSI DO Membrane Kits

The 5685 DO membrane kit is typically only used under special circumstances. The 2.0 mil membranes reduce sensitivity but are less affected by biofouling.

The 5776 DO membrane kit has a high sensitivity membrane to speed response time in cold water, but it is not as durable as the standard 1.0 mil membrane.

The 5775 DO membrane kit comes standard with the purchase of many YSI DO sensors and is desired for most standard monitoring applications.
