OxyGuard Handy pH
The OxyGuard Handy pH is a hand-held, pocket size pH/redox meter designed for use in demanding, wet environments. The meter itself and the electrode assembly are waterproof. This instrument does not suffer from the classical problems associated with pH meters – the Handy pH is sealed so that water cannot enter the top of the electrode or the electronics. You can drop it into the water without damaging it!
