Hanna Iron Checker ** EXPIRED REAGENT **

About this product

Hanna Iron Checker – Expired Reagent Included. A handheld digital colorimeter for measuring iron in water. The standard Hanna HI721 Iron Checker displays results numerically, eliminating the need to compare a sample against a printed color chart. Confirm the model number on this particular unit before applying the specifications below.

The supplied product title states that the included reagent is expired. Disclose this clearly: replace it with fresh, compatible reagent before relying on measurements. The expiry notice concerns the reagent, not necessarily the instrument’s condition or operation. Hanna identifies HI721-25 as the replacement reagent pack for the HI721.
