The JBL ProAquaTest CombiSet Plus NH4 is a freshwater master test kit that uses a comparator-block system to deliver simple, reliable readings of the key water parameters. It measures pH, carbonate hardness (KH), nitrite (NO2), nitrate (NO3), and ammonium/ammonia (NH4/NH3), and allows CO2 to be calculated via a table from the pH and KH values. The kit ships in a reusable case with 9 reagents, 3 glass vials, a syringe, comparator block, color charts, and instructions.
