Portable Dissolved Oxygen Meter with Easy Calibration Product Description

A Dissolved Oxygen (DO) meter is used to measure the dissolved oxygen content in liquids. The two most commonly used units of measurement are ppm (parts per million) and saturation percentage (%). [Note: The original text adds “That is, the percentage of oxygen dissolved in 1 liter of water,” which is not the standard definition of % saturation, so it’s omitted here for clarity in English].

• The operating interface is intuitive and easy to understand.
• Measures dissolved oxygen concentration and saturation percentage in water.
• Suitable for outdoor/on-site measurements, especially in rivers, lakes, seas, wastewater treatment, various aquaculture operations, and sewage treatment plants.
• Allows for direct on-site calibration. Operation is simple, requires no chemical reagents, and avoids tedious calibration procedures. Simply place the electrode in the air, press the “CAL” key, and calibration is completed in just a few minutes.
• The DO meter is an instrument used in aquaculture and aquarium management.
