£756.00 (ex. VAT)
Cable Length

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.

At Sterner we have a team of fully trained engineers on hand to service, repair and calibrate your handheld oxygen meters to ensure they're working accurately year round.

The service starts with a thorough inspection of the instrument to pickup on any faults there might be with the unit. This includes checking both temperature and oxygen reading against a calibrated reference unit to ensure accuracy. If there are no faults, the unit will then be renovated, calibrated and a calibration certificate will be produced.

If there are faults with the meter and it needs parts, you will receive a quotation for repairing it before any work is carried out.

Overview of service:

  • Initial inspection
  • Renovation
  • Calibration (incl certificate)
