If you’re still using DrinkSafe onboard your vessels, or even onshore, you’ll already be aware of the amazing benefit against infrequent onshore lab-based testing.

For a limited time, or as long as stocks last, we’re offering 70% off bacterial plates to use as part of your existing DrinkSafe Kit.

What are bacterial plates used for?

Bacterial plates are used to measure the Heterotrophic plate count (HPC) in your potable water presence of bacteria in your potable water.

A high HPC count is an indicator for ideal conditions for the growth of bacteria. This can be a breeding ground for more dangerous bacteria, such as Legionella or E. Coli, cause foul-tasting water, lead to corrosion or slime growth in pipes.

By testing regularly, you’ll have a better understanding of your HPC and be able to make an informed decision as to the water quality on board.
