The OxyGuard Handy is a portable dissolved oxygen
meter available in 3 different models - the Alpha,
Beta

The Handy measures both ppm (mg/l) and % Saturation. The Handy Alpha measures oxygen only. Both the Handy Beta and Gamma measure temperature in addition. The Handy Gamma has salinity compensation.
