pH is a crucial variable reflecting the chemical conditions of a given solution. pH affects the availability of nutrients, microbial activity, biological functions, and the behaviour of chemicals. As a result, monitoring or controlling the pH of soil, water and food or beverage products, amongst many others, is essential for a wide variety of applications.

Test once and test accurately with our digital pH meters, and don’t risk your next job with inferior testing equipment. Our high-quality, precision, and affordable digital pH meters are best for ensuring accurate pH readings in any situation.

This pH / ORP Controller allows you to monitor and control pH and ORP levels in one unit. The controller provides a suitable way for you to keep an eye on the different water parameters in your tank.
