Quick Overview

Why does BRS recommend this?


The Hanna Phosphate checker is an awesome little tool that will give you accurate easy to read results.  If you have bad eyes or have a hard time with color change test kits, the digital read out on the Hanna checkers is super easy to read.  The biggest key with Hanna checkers is keeping the vials nice and clean for consistent results.


Three simple steps to results. The Hanna Phosphate Checker bridges the gap between simple chemical test kits and professional instrumentation. Accurate, affordable and easy to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Hanna Phosphate Checker, press the button and read the results. Done.

Product Questions

I see on here that some users suggest buying the hi736 instead. Which one will work best to determine your overall PO4?
Question by: Justin on Jun 3, 2016 9:26:00 AM
Great question!
We personally use the Phosphate low range in house as it is accurate enough and we do not need to convert the reading from Phosphorous to Phosphate. While the Ultra Low range will give extra decimal placed to your answer We find this is not the most important. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jun 8, 2016 3:01:00 PM
Since the Hi713 and reagents are the same for both fresh water and marine, is it safe to assume variations of salinity will have no bearing on the results?
Question by: William Neiman on May 2, 2016 2:01:00 AM
Great question! That is a safe assumption to make, salinity should not effect the reading with this checker.
Answer by: Carter (Admin) on May 4, 2016 1:57:00 PM
how many test does this kit provide. Thanks.
Question by: Mark on Nov 30, 2013 6:00:00 AM
Hey Mark,
The phosphate checker itself comes with enough reagent for 5 tests. Reagent refills are sold in packs of 25 and can be found right here:

Does this meter require periodic calibration with some kind of calibration solution?
Question by: Eric on Jun 19, 2014 8:50:00 PM
Hi Eric,
One of the first steps every time you test is to zero out the meter, then you add reagent and test the actual sample. This is done every test but It does not require any sort of extra calibration procedure on top of that.

  • Wouldn't recommend for fresh or marine aquarium. By Keith on 5/21/2017

    This unit is great in theory but can't be counted on for accuracy under any stretch of the imagination. It test's 0-00 on my reef tank when that's qualitatively impossible for the condition. I've tested my tap water and only find 0.43 while the city says it runs on average 0.80. Tested other tanks with results of 0.00 when other test kits show trace amounts. Took my water to a local chemical test lab and found phosphate to be 0.02. I understand the accuracy, repeatability and reproducibility issues but shouldn't always be on the - side instead of +/-. I'm not particularly impressed with Salifert but it was the closest to Salifert. At least close enough to manage a marine aquarium.
  • Confused for why it is continuing reading 0.0 ppm By Jonathan on 4/5/2017

    I have had this product for about a month or 2 now and it keeps on reading 0.0, Not sure if i have a one that is broken. I will give a future review.
  • Excellent - reliable and accurate By Mitch on 3/6/2017

    I really think this is the best test kit you can buy for Phosphates. It gives you a very accurate reading and it gets the job done in about 5 minutes. Simple to use. I would though prefer the regent to be liquid than powder but other than that small detail this is a great item and I would recommend it to any hobbyist who wants an accurate reading.
  • Easy and quick By Rob on 12/8/2016

    This was my first HANNA checker purchase. Ive been hearing all the rage about these for a while so i finally tried. Very east and simple to use. Less then 5 minutes to test and get results. Definitely will be trying a few other HANNA checkers now.
  • **Be Aware** Not Suitable For Reef Aquarium Testing! By Julio on 10/16/2016

    Not sure why Hanna doesn't just Discontinue this product even though they know it's more suited for "Fresh" water than marine usage. I've owned this for 6 months and never had the digits read above 0.00 ppm! Had the signs apparently of having phosphates with algae growing constantly on my glass! Went and purchased RedSea's Phosphate test kit and Salifert's test kit just to make sure and too my surprise not only I had phosphates present in my reef tank but that the results showed RedSea 0.8 ppm Salifert 0.07 but yet my Hanba HI-713 can not detect these units! I emediatly called Hanna Headquarters in Smithfield Rhode Island and to my surprise, they told me that the HI-736 ULR which is the "Ultra Low Reading" test kit would be more suitable for me, which really indicates that thier aware of this problem! IMO, maybe they just never made an attempt to recall this model of kit in in order to save tons of money they just went ahead and slapped on the "Fresh & Marine " label and kept it as is but clearly if you don't see a "Fish" label in front of your handheld with the "Marine" label as well than it's not suitable for Marine! Unfortunately this problem is not going away! Reefers Be Advised, purchase the ULR instead!
  • The product it's really easy to use By Joseph on 10/2/2016

    Hanna Phosphate Low Range Colorimeter works well . Fast and accurate
  • Great.. packaging needs improvement. By Yus on 9/26/2016

    The product it's great and easy to use. Take away from having to match colors. However, the packages the reagent comes in need to be replaced with a scoop method because it's hard to get all the power out of the packages.
  • Unsure of accuracy By Mark on 9/3/2016

    Iva had this a couple weeks now and have yet to get a reading above 0.00 after 4 tests. I run hc gfo but should still have some phosphates right?
  • Really only 6 tests By Jaimeadams on 7/15/2016

    I am disappointed with the fact that it only comes with enough regent for 6 tests. Sure the digital read out is awesome and very helpful, but I really feel that for the price I should be able to test more than 6 times before having to give them more of my money
  • Easy to use By Eric Johnson 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 SD Reefer 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 KerryF 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.
