Manufacturer: Wildlife Supply Company Brand: Wildlife Supply Company

Measures dissolved oxygen to determine water quality in environmental testing, labs, industrial and municipal waste water, aquariums and fish hatcheries. Automatic temperature compensation as well as manual compensation for salinity and altitude (all factors directly affecting DO readings). Simultaneously displays dissolved oxygen (in % or mg/L) and temperature readings (in °C or °F). Review 99 data points readings directly on the large backlit LCD. Features simple one-button calibration to air. The electrolyte level is visible through the transparent galvanic probe with built-in temperature sensor. DO probe heads include built in membranes and screw on and off for easy replacement. Also functions as a pH and conductivity meter when used with the optional probes. Comes in a hard carrying case complete with pB (lead) free Galvanic DO probe with 9' cable, 2 spare probe heads with membranes installed, electrolyte and 4 AAA batteries.

Manufacturer: Oakton Brand: Oakton Model: WD-35441-02

The Oakton DO 600 Meter Kit contains a handheld dissolved oxygen (DO) and temperature meter with automatic or manual temperature compensation and a backlit multiline graphic LCD screen. It takes a galvanic probe, which has built-in temperature compensation and takes measurements immediately, without warmup time. The meter can store up to 500 data sets and has an Infrared Data Association (IrDA) wireless interface for downloading data to a PC. The meter has password protection for calibration and setup data, and the real-time clock for time-and-date stamping meets Good Laboratory Practice (GLP) standards. An audible alarm warns when readings are outside set points limit. The meter runs on four 1.5V AA batteries (included) or a universal AC adapter (sold separately). It has European Conformity (CE) certification and is dustproof and waterproof, with Ingress Protection 67 (IP67). DO meters are commonly used in water-quality testing applications.
