Product Details

Thank you for viewing.
This is a high-precision dissolved oxygen meter. I purchased it new on Amazon for my daughter's independent study project (retail price ๏ฟฅ12,999). I am listing it because it will not be used. I hope you can utilize it for your home aquarium or other purposes. I will ship as soon as possible.

Product description below.
Operation has been confirmed.
One diaphragm cap has been used, so 5 unused ones will be included in the package.
Zero calibration solution is not included, so please prepare it yourself.

The DO9100 offers a fast response time and a wide measurement range.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
