The original is back! The 'Oxyguard Handy Polaris' is widely regarded as the most reliable and accurate portable oxygen monitoring device in the market.
Portable oxygen and temperature meter complete with carry case and spares. The backlit display quickly and accurately measures, water temperature and dissolved oxygen in mg/l and % saturation.
The most reliable, robust and fool-proof oxygen meter on the market used by the most reputable fish farmers in the country. This is the only oxygen meter that we're happy to recommend at BP Milling due to its reputation and reliability.
Simple on/off button, check that the probe is reading within 1% of 100% and you're ready to test (quick and simple on-screen calibration if your handset isn't reading 100% saturation when dry). Not the cheapest oxygen meter on the market, but the best... and built to last! (I've had mine for 10 years this year and it still takes the same reading as a new model!)
