H2 hydrogen rich meter kedida ORP dissolved hydrogen concentration water test
Portable electronic testing meter to measure the concentration of molecular hydrogen in water.
This meter instrument is based on the reduction property of hydrogen and uses the oxidation-reduction potential (ORP) in the water as a measurement principle to convert the dissolved hydrogen concentration.  
The meter uses analytical technology and a high-sensitivity platinum sensor to make hydrogen measurement simple.
Factory calibrated and ready for use.
Ideal water temp for measurement is approx. 30? for best production of hydrogen for testing
