OxyGuard hand-held oxygen meters have proved their worth all over the world since 1989.

Before then, hand-held meters were expensive, fragile, slow and could not withstand getting wet.

All OxyGuard D.O. meters are waterproof, show D.O. in both % sat and mg/l (ppm), have automatic temperature compensation and are always be ready to measure. More advanced types have automatic calibration and pressure compensation as well as salinity compensation and data logging or data recording functions.

In addition there is, amongst others, the Handy Atmosphere, for measuring modified atmosphere packaging gas, the Handy pH, the Handy Salinity for salinity measurement and the Polaris 2 TGP for total gas measurement.

• Handy Polaris – to measure dissolved oxygen and temperature

• Handy Polaris 2 – to measure dissolved oxygen and temperature with data logging and data transfer capabilities

• Handy Polaris 2 TGP – for gas pressure measurement

• Handy pH – for pH measurement

• Handy Atmosphere – to measure oxygen levels in gas

• Handy Atmosphere SP – to measure oxygen levels of gas in food packages.

• Handy Salinity – for salinity measurements

• CO2 Portable – to measure dissolved carbon dioxide
