Regular monitoring of DO levels in the pond is not only essential but also critical for the good growth and survival of marine life. The most common method is to use indicators using the DO kits available in the market. But they do not give accurate readings and take a long process to give a reading. Which is why the hand held portable digital DO meter is the ideal product to take quick and reliable readings of DO levels. The display is large and easy to read. The process of using is very simple – just dip in the water and check the reading. And it has an automatic compensation for a temperature to give the correct reading for your pond.
