Regular maintenance is crucial for accurate DO measurements. Follow these steps for proper probe care:
4.1. Cleaning the Probe
- Durulama Probu: Gently rinse the probe with distilled water to remove any loose debris.
- Temizleme Solüsyonunu Uygulayın: Apply a small amount of the provided cleaning solution to a soft cloth or directly to the probe's membrane area.
- Yavaşça Temizleyin: Carefully wipe the membrane and probe body. For stubborn deposits, use the abrasive foil provided, but apply minimal pressure to avoid damaging the membrane.
- İyice Durulayın: Rinse the probe thoroughly with distilled water after cleaning to remove all traces of the cleaning solution.
4.2. Replacing the Membrane Head
The membrane head should be replaced periodically or if damaged.
- Unscrew Old Head: Carefully unscrew the old membrane head from the probe body.
- Prepare New Head: Take one of the new membrane heads from the kit.
- Fill with Electrolyte: Fill the new membrane head with the provided electrolyte solution. Ensure there are no air bubbles trapped inside. Gently tap the head to dislodge any bubbles.
- Screw On New Head: Carefully screw the new membrane head onto the probe body. Ensure it is finger-tight to prevent leaks, but do not overtighten.
4.3. Electrolyte Replacement
The electrolyte solution should be replaced when replacing the membrane head or if the probe's response becomes sluggish.
- Drain Old Electrolyte: If not replacing the membrane head, carefully drain the old electrolyte solution from the existing membrane head.
- Refill with Fresh Electrolyte: Fill the membrane head with fresh electrolyte solution from the kit, ensuring no air bubbles are present.
5. Depolama ve Taşıma
Proper storage of the kit components and the probe itself ensures their longevity and readiness for use.
- Store the kit components in a cool, dry place, away from direct sunlight and extreme temperatures.
