Key Benefits

• A dedicated refill matched to the Hanna HI782 Nitrate High Range Colorimeter.
• Formulated for marine water, so it suits saltwater aquarium testing rather than general-purpose use.
• Enough reagent for 25 tests, letting you track nitrate trends over many readings.
• Pairs with Hanna's digital Checker format for a meter reading instead of guessing at colour-card shades.
• Keeps your existing HI782 meter in use, so there is no need to replace the instrument when reagents run out.
