TheHanna Nitrate Checker是一种全新的水测试套件，与当前在水族馆爱好中可用的方法相比，采用了非常不同的测量硝酸盐方法。这个低范围colorimeter专门设计的盐样品中的NO3最高可达5mg/L，但是在此范围内，与盐水业余爱好者目前可用的任何东西相比，它提供了更高的分辨率和准确性。
尽管典型的水族馆硝酸盐测试通常成本约为20美元，并从零到50 O 100份量的NO3量，但要尝试评估从零开始的颜色变化到百万分之二，这将是非常困难的。The best range of ‘results’ you can expect from hobby nitrate test kits falls under a few categories including ‘there is NO nitrate’, ‘there is SOME nitrate’, ‘nitrate is SAFE but a little high’ or ‘Nitrates are WAY too high’.
在许多情况下，这实际上对于对水族馆化学的日常分析实际上是可以的，但是对于更高的能量珊瑚礁储罐没有任何作用，在珊瑚和生态系统中迅速消耗了硝酸盐。尽管ELOS等标准范围测试套件可能会覆盖广泛的范围，并且在短短几分钟内就非常容易执行少量测试，但为了更准确，Hanna硝酸盐检查器为用户提供了更仔细的观察硝酸盐浓度开始接近零。
If you’re familiar with the Hanna Checkers, the box itself and the contents inside will be pretty familiar but there’s quite a lot of extra parts, and some new steps that we haven’t seen in the range. The most different new step in performing water analysis with the Hanna Nitrate Checker is pushing the reacted sample through a filtration chamber after mixing first two reagents to remove all the particulates.
We won’t sugar coat it; performing our very first test with the Hanna Nitrate Checker took around 45 minutes including reading the directions thoroughly, misaligning the filter pad in the housing and making a mess, then starting over due to a mistake. At times like these we wondered why we were even bothering to go through all thiseffortto measure nitrates that we already knew were ‘fine’, but after getting past the short learning curve we were able to get the entire test down to 10 minutes total per sample, plus the obligatory eight minute wait for the Nitrate Checker to perform its reading.
We measured the nitrate using our go-to Elos nitrate test kit on five tanks,估计的与图表上的颜色相对应的值，然后用Hanna硝酸盐检查器更加有条不紊地重复测试，以评估它们的比较。根据ELOS测试的三个珊瑚礁显示和系统基本上为零硝酸盐，为0.0、0.07和0.17mg/l - 微小值 - 微小值，但仍然很有帮助，但我仍然知道我真的应该给这些水箱喂更多食物为促进珊瑚的生长。
But what was more surprising is that the higher nitrate samples had much more discrepancy with the saltwater fish system measuring around 5mg/l using the Elos test, but 13mg/l with the Hanna Nitrate Checker. Meanwhile the saltwater fish display exhibited an even wider difference between the tests, eyeballed to be around 17mg/l with the Elos test but resulted in a value of 55.6mg/l using the more involved 3 reagents, filtration and colorimetric measured provided by the Hanna Nitrate Checker.
(It’s important to point out that the Hanna Checker only resolves nitrate levels up to 5mg/l so there is a dilution procedure required to bring high nitrate water within the range, and it’s entirely possible we made an error during this step resulting in the major difference.)
通过改变色彩的滴定测试套件来测量钙和碱度，但根据您的照明或彩色视觉，可能很棘手。对于这些珊瑚礁水族馆的化学价值，汉娜检查员只能使用一些更难，但具有更高的精度和可重复性。
相反，水族馆的硝酸盐测试遍布整个地图 - 我们认真地尝试了所有这些测试，它们很少给出可重复的结果，更不用说低端的零分辨率了。但是，“易于使用”这些水族馆测试套件可能适合可疑的值，汉娜硝酸盐检查器并不难使用，但是它确实需要时间和步骤更多，而不是更多的盐水和礁石水族师习惯于表演。
Most reef aquarium chemistry sets will be best served by having both a quick and easy nitrate test kit that only gives a rough idea of what nitrate levels are, as well as the Hanna Nitrate Checker for better understanding on the rate of nitrate buildup or consumption. The aquarium hobby has never had access to this level of nitrate testing, not even from ICP tests, so it’s still too early to know what we will learn once more people get the Hanna Nitrate Checker in their possession, but we’ve already confirmed that we havea lot在我们自己的礁石水族系统中，更多的净空可以喂养鱼类和珊瑚。
