Good Set - With Restrictions

The tests are at JBL tend to be somewhat more accurate (more detailed scale). For example, when nitrite and nitrate. Only the pH test is not very accurate (0.5 steps). This is annoying, since JBL indeed accurate test has the program but these are only in the big suitcase.

The manual is good and stable as stapled at Sera. Exemplary is the test system and color scales. So one feels always two glasses with and without Regagenz and can thus compensate for the water turbidity. The Sklalen in a folder with ring binders are also in the focus the instructions say. So you do not always take at hand the manual.

In addition there is a separate block with lists where you can enter the values. A "Excel list" (Calc, Excel) is in my opinion better :-)

The choice of values ​​is good. What is missing is the ammonium / ammonia Test (important!) And the phosphate test. GH (general hardness is rather unimportant) and also missing.

Good solid case certainly worth its price. But would the purchase of "PH 6.0-7.4" and NH3 ... or buying the large suitcase ...
