One Time Calibration - Cheaper Cuvette Replacement By Brian on 9/30/2016
Brian wouldn't recommend this product to a friendI should have read the other reviews. This purchase makes sense if you have broken the glass cuvette from another test. Rather than spend $20.99 for 4 cuvettes, order this for $11.99, perform the single test the kit allows, and now you have two replacement cuvettes. I am disappointed that Hanna is unable to provide a test that allows repeated calibration testing of phosphate. -
single use item By Mike on 12/18/2014
Mike wouldn't recommend this product to a friendI was caught by surprise by this. It's a single use calibration test.
wish I'd seen David's review before ordering. Hopefully a 2nd review will help draw attention to this. -
Pricey, one and done, wrong range By David on 8/23/2014
David wouldn't recommend this product to a friendSeveral problems with this standard. First it isn't clear in the description but it's a one time use standard. Basically a cuvette with a known amount of phosphate. You do your normal test and compare your results to the standard, The additional problem is the standard is 1.0 and we should be measuring tank water with 0.04 to maybe 0.3. Not the best standard for the range we're testing for. Not worth $11 IMO.
