The pH is in all respects a measure of acidity and alkalinity, pH 0 - 6.99 is acid; pH 7.0 is regarded as neutral and pH 7.01 - 14.0 is alkaline. On the whole the pH is not generally a problem but it can have a profound effect on the toxicity of ammonia. Alkaline water, that is with a pH of over 7.01 in combination with increasing temperatures causes more of the ammonia to exist in the free form, which is very poisonous to fish.

The higher the pH and water temperature the greater percentage of the ammonia which exists in this harmful free form. If the water is alkaline it is worth bearing in mind that this will affect the toxicity of ammonia and that even very low readings could therefore be quite serious for the welfare of the pond fish.

The pH of the pond is largely dependent on the pH of the make-up water in the surrounding area and therefore it is not possible to try to control this parameter artificially.

The ECO Pal pH Meter measures pH, one of the more important control parameters in Koi ponds. Having a rugged, reliable and portable tester is indispensable to Koi hobbyists on the move.

Auto Shut Off
The energy-saving feature shuts off the tester when it is idle. To ensure accurate reading at all times, the unit displays a low battery sign to alert user to change the batteries before it degrades the accuracy of the reading and data.

Water Resistant
The ECO Pal pH Meter is made to be splash proof, allowing easy washing of the unit. Even if the tester is accidentally dropped into the water, it will remain afloat so as to enable user to retrieve it immediately without damaging the sensitive electronics in the unit.
