This refill is intended for the JBL PROAQUATEST NH4 test. It allows you to monitor the biological balance of the tank by measuring ammonium and ammonia, essential indicators of bacterial activity and water quality.
Fill the glass test tubes with the water to be tested, add the reagents to one test tube, then place both test tubes in the comparator block. The value is read using the provided color chart and conversion table.
Refill compatible with the JBL PROAQUATEST NH4 kit, allowing the test to be used longer without replacing all the equipment.
