NPK Reagent A (500ml)

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.

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

This is a bulk refill solution of NPK Reagent A(500ml) which has the volume for 100 sample measurements. For convenience this can be used to refill the 100ml solution in the Kit.

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.
