Description
The Hanna Marine Nitrate LR Handheld Colorimeter – HI781 brings Hanna Instruments quality to your reef — dependable, high-performance gear that serious hobbyists trust.
The Live Arrival Guarantee covers livestock; equipment, test kits and other dry goods ship at their own rate and do not count toward the $299 free-livestock-transportation threshold. We keep and run this equipment ourselves, so reach out anytime for setup or compatibility help.
Shipping & Returns
- Equipment and dry goods ship at their own rate. Free shipping at $299 or more applies to qualifying livestock only — corals, fish, inverts and live copepods. The $20 Box & Handling Fee is a livestock packing fee and does not apply to dry-goods orders.
- All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
- Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
- Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
