HORIBA LAQUA DO220 Waterproof Handheld Dissolved Oxygen & Temperature Meter
Product Overview
The HORIBA LAQUA DO220 is a professional handheld meter for measuring dissolved oxygen (DO) concentration, percentage saturation and temperature in water. Designed for dependable laboratory and field use, it features an IP67 waterproof and dustproof housing, a backlit display, automatic compensation functions and onboard data logging.
The meter uses a galvanic dissolved oxygen probe with an integrated temperature sensor. It automatically compensates measurements for salinity, barometric pressure and temperature, helping provide reliable readings across different water-testing conditions.
