Hanna Marine Ammonia Checker Reagents (25 Tests) - HI784-25

These are replacement reagents for the Hanna HI784 Marine Ammonia (ppm) Checker HC handheld colorimeter. Each pack supplies 25 tests, so you can keep checking ammonia in your saltwater system long after the reagents that came with the meter have run out.

The reagents come pre-made, which means there's no measuring or mixing on your part. You simply add them to your sample as part of the normal Checker routine. They're prepared with high-purity chemicals, helping keep your readings consistent from one test to the next.

Every packet is printed with its lot number and expiration date, so you can trace what you're using and see at a glance whether a packet is still within its date.

They suit anyone who already owns the HI784 Checker HC and wants to keep monitoring ammonia in a marine tank, whether you're cycling a new setup, introducing livestock, or checking on an established reef. Note that these are reagents only and work with the HI784 meter, which is sold separately.

Size: 25 tests. Product code: HI784-25.
