Description

AVAIN LABS® Pocket Dissolved Oxygen Meter DO-66

AVAIN LABS® Pocket Dissolved Oxygen Meter DO-66 is a compact and portable digital instrument designed for accurate measurement of dissolved oxygen (DO), oxygen saturation, and temperature in water and liquid samples. Its pocket-sized design makes it suitable for laboratories, water-quality testing, aquaculture, environmental monitoring, educational institutions, research facilities, and field testing.

The DO-66 uses a thin-film dissolved oxygen electrode and an electronic unit with automatic temperature compensation (ATC) for convenient and reliable measurements. It can display dissolved oxygen in both mg/L (ppm) and % saturation, making it versatile for a variety of water-analysis applications.
