Has anyone used this unit before HI83300-01
Multiparameter Benchtop Photometer and pH meter ? I am wondering if this is the unit where you can take any one of the various handheld colorimeter units. place it in the socket and test.
Theabovelink has details about it and lists all the tests it can do. it basically works the same way as the $50 checkers that were mentioned earlier. However unlike the checker that can only do one test, this unit can do about 50 different tests However not all the tests it can do are aplical to aquariums. It can however test for all the macro nutrients (N, P, K, Ca, Mg, S Cl) a few micros (Fe, Mn, Cu, Ni) Gh, Kh, PH, Ammonia, Nitrite, Nitrate.
Please note the ranges listed in the tests. Some tests are low rang, mid range, and high ranges for the same element. You want to use the tests that are in the range typical for an aquarium. One test for Zinc (a micro nutrient) is only for high range ppm range while most aquariums are in the low ppb range. So the Zinc test isn't that useful Other tests are for marine tanks while most are for fresh water. IF you can afford it it is useful. but in many case great accuracy i not always needed.
I have looked at it and the higher priced version that can do even more tests but do you need all that? Another option would be to buy a few low cost tests and occasionally send out a ample to a lab for a ICP-OES test that can measure 13 of the 14 nutrients down to 0.001ppm for $30 a tests. I am currently thinking the $30 lab test and a few $50 checkers. PH pen, and TDS meter are a better route.
While I really like the Hanna checkers I worry that they may abandon the product. Many of the checkers they release were mainly geared for water contamination monitoring, or laboratory tests. Many the checkers are not useful for aquariums. And the one checker many people want a nitrate checker was never produced. Only a couple of new checkers were release after the initial product launch and nothing has been added in the last several years.
I was reading about another unit that was priced at approximately$1200 but I can’t seem to find the article. sure it is costly but I digress I’d still like to learn
There are about 9 different models: The more tests a unit can do the higher the cost.
