About this product

Phosphates routinely enter the natural environment from sewage treatment plant effluents and agriculture as well as from many domestic laundry detergents. Excess phosphates in the environment lead to algae growth which prevent light penetration and use oxygen and subsequently lead to poor water quality. Monitoring of phosphates is therefore a key step in environmental awareness and this great value Pocket Checker is an excellent addition to any water testing kit.

This item is also an excellent choice for aquarists for whom regular monitoring of aquarium water quality is of the utmost importance.

The Pocket Phosphate Checker comes complete with 2 sample cuvettes, 1 black cuvette cap, a starter pack of 6 reagents, 1 x 1.5V AAA battery and full working instructions.
