  • Easy to use By on 4/6/2016

    I hate trying to match colors on tests (ok, I'm also slightly red-green colorblind so that doesn't help!) and this makes it so much easier. Doesn't come with very many test packets so if you'll be doing a lot of testing you'll want refills but they're pretty inexpensive.
  • Dies right after warranty By on 4/6/2016

    Problems with the light sensor the minute the 6 month warranty was up. Randomly worked and then completely dead. Tech support offered up $95/hour service or they said I'm welcome to order a another from them. Don't think so. The results I was able to get when it worked were extremely varied and I couldn't stand trying to get all the powder out of those tiny packets. Need to rethink design on those. Not pleased unfortunately.
  • Great Checker By on 3/29/2016

    One star off for those silly packets for the reagent. Works well and seems very accurate. Lid seems to have a hard time staying closed with a vial in it the checker...no big deal really.
  • Nice for Accurate Low Range Testing By on 3/18/2016

    Like many other Hanna checkers this product takes the guess work out of phosphate testing. I have a special loathing for trying to decipher color coded phosphate test kits and this helps me solve that issue. I had to take 1 star off because getting the power into the vial is brutal, and I mean brutal.
  • It works, just have to get use to the reagents. By on 3/5/2016

    Good too have two vials. One to set the checker, the other one to have the reagent all ready mixed.
  • Pointless By on 1/20/2016

    Save your money. I get more accurate results using API phosphate test and its significantly less money. Measures ppm just like API however the Hanna checker shows 0.00 and API shows 0 to 0.25 ppm. Even contacted Hanna to see if it was broke and their first response was to buy the HI736. So they seem to be aware that it's junk. Also, once you open the box it's yours. Bulk reef supply does not except returns on opened items. A little hard to consider buying a second piece of equipment when the first one doesn't work as it should. Also bought the HI758 calcium checker that works flawless. Watch the YouTube video as the instructions are not clear.
  • Works great By on 12/17/2015

    'Reagent packets are difficult to open and pour into vial without spilling any. Otherwise it works great.
  • Not for Reefers By on 10/29/2015

    First and foremost, if you are a reefer, this is not the checker for you. The ULR is the right one for a reefer. This will measure to an accuracy of +/- 0.04 but as a reefer you want 0 to 0.03 so that makes this useless. Oh and the packets of reagents are not good at all, come on Hanna get the proper reagents made already.
  • Love that you get an exact readout. By on 10/26/2015

    This would be the ultimate tester if the reagent was alittle easier to manage. You are trying to poor powder from a little pouch into a tiny cylinder you think you got it all then you realize there is still powder stuck in corner of pouch... Then you ask is my test result accurate?? They need to come up with a better solution to adding the powder even if just a bulk buy option that comes in a container with a little scooper like the nyos or salifert powders come. And to top all of that of you are on the clock when you are trying to get this powder into test tube you have three minutes to get powder from pouch to tube without spilling then you need to get it completely mixed into water without air bubbles or finger prints or the machine turns off then you are left to recalibrate machine with different test tube of source water then test water powder is in... Is it accurate???? Exactly hate questionable results but once you get hang of can definitely get a number and much more accurate then any color matching test out there... Just need a better delivery system for reagent and problem solved.

    Works like a charm for me. I'm a bit color blind, this really helps.
