Hanna HI702 High Range Copper Colorimeter - Checker

Great product. Does exactly what it should. It is easy to use.

Very accurate and precise digital test device. I much rather use this over other test equipment for his precision and just needing water and pillows to get a good test result versus measuring out with a syringe.

Does what it's supposed to do.

This tester completely takes the guesswork out of checking copper levels. The digital readout is clear, accurate, and much easier to trust than trying to match colors on a chart. Setup was quick, the unit is compact, and it came with everything needed to get started. After using it during copper treatments in my quarantine tank, I can say it’s worth every penny. If you rely on copper in your aquarium, this is a must-have tool.

Works well. Returns results quickly.

Easy to use an accurate, but only six reagents were included in the package and I need to check it every day! Ridiculous for the price someone is paying for this product.

Exactly what I needed to accurately dose copper in my salt water tank. Well worth the money, however you should buy an extra pack of reagents if you are going to test daily during treatment as the Hanna tester only comes with 6.

Item should have included: A. Scissors ✂️ to cut the chemical pouch. B. 15 not 6 chemical test packages. C. Lint free cloth. D. Measuring beaker for copper liquid or dry powder. E. Calculations on the amount of copper to and base on ppm and amount of added. F. Pool copper levels should be between 0.3 and 0.4 ppm as a reference. Better directions, i.e. 1. Hold on button to turn on. 2. Place vial inside the unit. (Pool water to 10 ml without test chemicals). 3. When you see C1, press the on button (do not hold). This will zero the unit. 4. You will see " - - - " flash for 10 seconds. 5. When you see the C2. Prepare vial and insert into the unit. (10 ml of pool water plus 1 pouch of test chemicals. Rock back and forth for 1 minute to dissolve the test chemicals). Press on hold the on button. You will see 45 second count down followed by " - - - " for 10 seconds. 6. Copper ppm will then be displayed.

It is much better than reading the Copper level manually. The Digital Meter is a Game-Changer. Only concern is: It is extremely pricey and you also get 6 agents; which means you should buy extra agents that can cost you upto $40. Also, it does not come with a syringe to retrieve the water. Overall Good but very pricey.
