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.

This can be used in aquaculture, beverage, fish hatcheries, water ponds, whirlpool, spa, food processing, photography, laboratory, paper industry, swimming pool, plating industry, quality control, water conditioning, and schools.
