OxyGuard Handy POLARIS oxygen meters

Oxygen meters, a great selection of products for instrumentation available at Aquamerik. Contact us if you wish for more information about our products.

The OxyGuard Handy Polaris is a portable dissolved oxygen (D.O.) meter that also measures % saturation, mg/L (ppm), temperature and has salinity compensation. Measurements are compensated for temperature and barometric pressure. The probe is galvanic type and fully field-serviceable. Has a large display with backlight and offers automatic calibration and the choice of language and units of measurement. Each unit is supplied with a detachable clip for easy attachment to a belt or clipboard.

The OxyGuard Handy Polaris 2 combines the features of the original Polaris with the convenience of data logging and data transfer capability. The Polaris 2 has a larger display with backlight and offers automatic calibration, and the choice of language and units of measurement. Includes a detachable clip for easy attachment to a belt or clipboard. USB compatible with software (can be used with multiple units).

Dissolved oxygen measurement

Oxygen meters can determine the amount of dissolved oxygen in a liquid solution. We generally express this quantity of oxygen in parts per million (ppm) or in percent saturation (%), defined as the percentage of dissolved oxygen in 1 liter of water. The amount of dissolved oxygen is a good indicator of water quality. It is essential to control the dissolved oxygen amount in water treatment, where low oxygen concentration is synonymous with pollution.
