I am looking for a piece of kit that I can add a sample of marine water to and it will tell me how much of the following is in that sample and print the values out either on a laptop or printer
Phosphate
Nitrate
Nitrite
Ammonia
Calcium
Iodine
Strontium
if there is such a beast out there I know it would cost a small fortune but it would be worth it to me
thanks dewi
