NPK Reagent A (100ml)

The NPK Reagent A is required to measure Phosphorus in aqueous feed or drain samples. This reagent is not required if you are measuring just N (Nitrogen) and K (Potassium).

A 100ml bottle of Reagent A is supplied in the NPK Meter Kit along with a colour coded 5ml Syringe. The Bottle is colour coded with a Green Label and the syringe coded with a green collar.

When making a P measurement you will be prompted to add 5ml of reagent A to a 50ml sample and wait for 60 seconds before adding 5ml of Reagent B.  To perform a P test you need both Reagent A and Reagent B.

There is enough in the bottle supplied to perform 20 P tests.

There is a bulk refill solution available NPK Reagent A(500ml) which has the volume for 100 sample measurements.
