Hanna Instruments Checker Marine Ultra Low Range Phosphate Colorimeter Reagents (25 Tests)

$9.00 


Item #: HN7745


In Stock

The HI774-25 are the replacement reagents for the Marine Ultra Low Range Phosphate Checker Colorimeter (HI774). These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

The HI774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker® HC. These reagents follow the Ascorbic Acid Method in which the reaction between phosphorus and reagents causes a blue tint in the sample. By simply adding the packet of HI774-25 reagent to the sample, the reaction will take place and the HI774 will determine the concentration from the color that is produced. The results will be displayed in ppb of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate.

Features:

  • Pre-made reagents for ease of use 
  • Prepared with high purity chemicals
  • Marked with expiration date and lot number for traceability

Yes, I would recommend this.

Hanna is the best

Pros: Best Result as Close as Possible

Cons: Taking ALL powder out from sachet is a challenge sometimes.

Hanna Phosphate ULR is teh best tester a reefer can ask for. IT is not 100% precise but will give you best possible result / test output. Bit troublesome to take all the powders out. But well worth it.

Hannah phosphate reagent

Pros: Fast, accurate

Cons: Test vial must be clean

I have been trying to get phosphate levels down, so I test every other day or so.
This test fives fast results with no guessing like with a colorimeter.
Make sure the test vial is clean of fingerprints and water drops or the reading will be false.

works

same as all the hanna powder reagents, could be a better way to package. you must work the packette before opening it to ensure no reagent will be lost when cutting open. watch video on how to use and it will help. once you get the hang of it, they're not bad

Test packets

Pros: good price

Cons: hard to find right ones

I don't think I got the right ones you need to put them all on one page so a person can look at them all to find the right ones. or show tester and packets that go with it on same page
