The OxyGuard Handy Polaris is a portable 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 a choice of language and units of measurement. Each unit is supplied with a detachable clip for easy attachment to a belt or clipboard. Battery life allows up to 1,400 hours of use from a single 9V battery.
• Automatic calibration with stability check.
• Compensates for changes in atmospheric pressure.
• Automatic shutdown for power saving.
