Hanna HI702 High Range Copper Colorimeter - Checker

All Hanna Products are excellent. Just be ready to pay for the pricy reagents

Works good and test only takes 45 seconds.

Does what it says with great accuracy. I have been using it for about 4 months and would totally buy it again.

Great product but the one I recieved was definitely used. Missing one reagent wet wrinkled instructions. This was sold as new beware of purchasing from amazon maybe get this directly from the manufacturer.

Helped me have piece of mind when quarantining my fish in copper

The media could not be loaded. Seller sold me this as in “good condition” item was all corroded inside where the battery goes, battery was left inside and oxidized, item wouldn’t come on!! Changed battery showing errors and would not come on every time I tried. Missing instructions total disaster. What a disappointing experience waited two weeks for this!!!

Quick and easy to use.
