Disssolved Oxygen Meters & Accessories for Water, Aquarium, Do Meter Oxygen Analyzer with 3.6ft Probe for Koi Pond Aquarium, Measure DO in Water, Aquaponics
Includes: One pc Dissolved Oxygen meter; 9 replacement membrane cap and 3 bottles of electrolyte solutoin, meeting the consumable needs of customers who frequently use the dissolved oxygen meter
Digital Dissolved Oxygen Meter: Has two measurement units: mg/L (dissolved oxygen content per liter of water) and % (percentage of saturated dissolved oxygen). Test Range is 0.0-40.0 mg/L and 0.0-300.0%. Do Meter comes with a 3.6-ft (1.1-meter) electrode cable, making it easy to measure dissolved oxygen levels in small fish pond and also includes one bottle of zero-oxygen water calibration solution, two bottles of electrolyte solution, and six membranes, making it very convenient to use
How to replace the electrolyte: Pour out the old electrolyte from the membrane cap add new electrolyte, clean the membrane cap, then pour out the old electrolyte again, and finally fill the membrane cap with new electrolyte
Digital Dissolved Oxygen Meter for Pond: For most aquatic life, oxygen levels must be at least 6 mg/L. Use a pond oxygen meter to monitor oxygen levels in aquariums, ponds, fish tank, koi pond, and goldfish ponds to ensure your ponds has enough dissolved oxygen to keep aerobic lifeforms happy
Portable Do Meter for Hydroponic: In hydroponic systems, especially deep water hydroponic systems such as NFT, RDWC, drip irrigation system, and aquaponics, it is very important to use the dissolved oxygen meter to monitor the dissolved oxygen content in the hydroponic nutrient solution for the health of the plant roots. Most hydroponic plants require a dissolved oxygen content between 5-10 mg/L. The EZTOCH dissolved oxygen tester helps you build a healthy hydroponic system
