Fauna Marin Multi Reference 100mlWith the Fauna Marin Multi Reference Solution, you can test your test kits under accurate conditions. Our Reference Solution is the first to be based on a saltwater matrix and is quality tested using our ICP AES testing machine. We use a saltwater matrix that is similar to aquarium water so that all common variables which affect normal water tests are taken into account. Each batch is quality controlled and tested in our Seawater Research Laboratory
