Totally agree with this. My LR and HR are pretty much identical in terms of results. However, i do love not having the extra steps and smell reagent anywhere near meThe low range kit isn't nearly complicated as it is made out to be but right tool for the right job so it is good to see this come to market.
For anyone interested in pre-ordering additional reagents, Hanna charges $18 for shipping these little packets. Saltwater Aquarium is taking pre-orders with $0 shipping.
My nitrates don’t move that much so the ten reagents should last me over a month(hoping I won’t need to pre order for those either). I’m excited to get a number read out. Those that don’t mind the color readings won’t be as excited for this I’m sure. The easier the test the more likely I am to perform it.
It’s one more addition to my hanna arsenal, now I’m just hoping they simplify the calcium checker somehow.
I just read a few people worried about getting more reagents. I don’t think that will be an issue in a month from now. the initial 10 should get me there. Testing twice a week till I start to see a drop in nitratesIt always amazing me that the manufacturer always seems to charge more than a distributor, even tho Hanna would have sold the product to them at a greatly reduced price, but the store can still sell at a profit and still offer reduced price shipping, yet the manufacturer changes $18!
If it doesn't move much why are you testing so much?
I was expecting you to say the reagents should last you 2-3 months not a month
Just got this as well. Trying to figure out if I dropped my nitrates or if this reading is different than what a RedSea test would show.
Went from 32 on Red Sea to 12.9 on Hanna. I did make some serious changes but was shocked it was that big
Once you get over 5.0, you're supposed to dilute the measurement. Once you dilute it, the accuracy is worse with +/- 2.5ppm. It's likely your high range checker is more accurate for you now.Okay,
So, I ran the both the LR vs HR Hanna on my SPS system. Here are the results of that test.
LR = 5.6 ppm vs HR = 6.9 ppm
LR has 0.25 +/- accuracy for error
HR has 2.0 +/- accuracy for error
The numbers are very close even if you enter the error rate:
HR = 4.9 - 8.9 ppm factoring error
LR = 5.35 - 5.85 ppm factoring error
I am still well below the 10ppm for Nitrates with SPS dominant system with the HR test for error/accuracy, so for a quick bench mark for reading Nitrate, the Hanna HR gets my approval considering you get results in less than 10 minutes with 1 regent!
Okay, good to know! If I get a HR reading in the future below 5ppm, I will go back to my LR and redo the test to see the difference. Thank you for catching my error in data. It was late last night and I only ready .25+/- on the back of the box, little did I know that calculation for error is observed for 5ppm and below readings.Once you get over 5.0, you're supposed to dilute the measurement. Once you dilute it, the accuracy is worse with +/- 2.5ppm. It's likely your high range checker is more accurate for you now.
I ordered mine from https://www.saltwateraquarium.com/ yesterday. Expected stock date July 6th. I just checked their site and it is still showing the 6th; i hope that date is right.Yeah so I think there's this slow catchup, everyone is getting their HR checkers then realizing they need reagents. I placed my order for reagents with Hanna direct from their website yesterday and today I have an email saying they're backordered; expected ship date is July 20th!
