DO9100 Digital Dissolved Oxygen Meter Waterproof Water Quality Tester

Monitor oxygen levels with confidence using a portable tester designed for reliable water quality checks. The dissolved oxygen meter measures oxygen concentration from 0.0-30.0 mg/L and saturation from 0.0-300.0%, providing useful data for aquatic environments and water systems. Built-in automatic temperature compensation helps maintain consistent measurements as water temperature changes. Its IP67 waterproof housing, backlit digital display, and portable design make testing convenient in both field and laboratory environments.
