The Flir Extech DO603 Membrane Kit is used for the maintenance and replacement of the membrane cap on dissolved oxygen meters, ensuring accurate and reliable measurements.
The membrane should be replaced every 6 to 8 weeks or whenever it becomes damaged or exhibits inaccurate readings.
To replace the membrane, remove the old membrane cap, fill the new cap with electrolyte solution, and securely attach it to the probe. Ensure there are no air bubbles in the membrane.
Check for air bubbles under the membrane, ensure the membrane cap is tightly sealed, and verify that the electrolyte solution is fresh and properly filled.
The membrane should be gently rinsed with distilled water if dirty. Avoid using harsh chemicals or abrasive materials to prevent damage.
Calibrate the meter by immersing the probe in a calibration solution or saturated air, and adjust the meter settings according to the manufacturer's instructions.
Air bubbles can cause inaccurate readings by disrupting the contact between the electrolyte and the sensing electrode, leading to measurement errors.
Use the specific electrolyte solution recommended by the manufacturer, which is typically included with the DO603 kit, to ensure optimal performance.
Yes, the DO603 membrane is designed for use in both freshwater and saltwater environments, but calibration may differ slightly between the two.
Signs that the membrane needs replacement include physical damage, persistent air bubbles, inaccurate readings, and slower response times.
