[What’s in the Box] Membrane Cap*6; Electrolyte Solution (30ml) *2; Zero Oxygen Solution (50ml) *1;
[Zero Calibration is Required for First Use] Zero Oxygen solution helps maintain the accuracy and reliability of dissolved oxygen meter; it’s recommended that zero calibration is required for first use. Calibration ensures accurate readings. This helps keep the DO concentration in check for the health of aquatic life.
[Improves the Longevity of the Tester] Easy calibration for saturated air (slope calibration) and zero-oxygen (zero calibration) with automatic identify program. Anyone even an amateur can complete the slope calibration easily before each use. UIUZMAR also provide detail user manual and video about how to use and maintain the DO meter.
[Ensures Accurate Readings] UIUZMAR Dissolved Oxygen Meter using replaceable oxygen-permeable PTFE membrane cap can always give accurate and consistent readings. This semipermeable membrane isolates the sensor elements from the environment but allows oxygen to enter. If any damage is evident (such as wrinkles or tears-holes), the membrane should be replaced.
[Double Sealed] 2-year expiration from manufacture for an unopened bottle. Store in a cool dry place, away from sunlight.
