- Ammonia Low Range Colorimeter HI700 Hanna Checker - Fresh Water
Four simple steps to results. Easily and accurately test for low range ammonia in fresh water with the Hanna Checker Colorimeter - Ammonia Low Range for Fresh Water (HI 700). Designed to be more accurate alternative to chemical test kits. First, add sample to the included cuvette. Next, insert sample into the Checker and zero the instrument with your water sample. Then, remove sample and add the reagent. Finally, place the vial into back into the Hanna Checker, press the button and read the results. Done.
Easier to use and more accurate than chemical test kits.The HI 700 from Hanna Instruments uses an adaptation of the ASTM Manual of Water and Environmental Technology, D1426-92, Nessler method. The reaction between ammonia and reagents causes a yellow tint in the sample. Auto shut off after 10 minutes of non-use.
Dedicated to a single parameter
Two sample cuvettes and caps. One bottle of reagent A and one of reagent B.
Small Size, Big Convenience
Weighing just 64 g (2.25 oz.), the Checker®HC easily fits into the palm of your hand or pocket. Use for quick and accurate on the spot analysis. Single button operation: Zero and Measure Operated by a single AAA battery.

Very accurate By Steve on 6/29/2020Steve would recommend this product to a friendI am getting reading of 0.00 or 0.05 on my pond. I think this is normal and healthy, as there will always be traces of ammonia in a koi pond since the filter bacteria will not eliminate it instantaneouly. Fish seems healthy, so gotta believe this test is good. It test NH3-N, not the total ammonia typical of other test kits like API. Those kits are very misleading as all ammonia tests require PH, temp, and a measure of ammonia, use of a conversion table to determine the relevant measure of toxic ammonia. Toxic ammonia is much less than total ammonia, but increases dramatically with temp and PH. A total ammonia test result of .25 would be alarming to an aquarist. However, this would only be toxic if PH was above 9 and temp above 85F (roughly). So any test kit with low resolution total ammonia measurement is not going to be very helpful, which is why Hanna Checker is likely the superior product on the market for testing freshwater ammonia toxicity.
Great Ammonia Test Kit! By Dean on 12/8/2014Dean would recommend this product to a friendHaving become frustrated with three or four different Ammonia test kits I made the plunge and got this one. Accurate, yes. Ease of use, yes. Results that I can count on, yes. Repeatable results, yes. Okay it is a little more expensive but I was getting so many mixed results with the other brands of kits by the time you add up the costs and frustration it is well worth it. Now I wish I would have bought this one first and saved lots of wasted money on the less expensive kits.
Do you sell replacement reagents for the ammonia thanks
How many tests can be performed with this kit?
Have a great day!
i was wondering if this ammonia checker although it is stated that is for fresh water, can it work with saltwater as well?
would it be as accurate?
This ammonia checker is only compatible with freshwater. Its generally used by people with saltwater aquariums who want to check there tap water for ammonia content (which would be indicative of chloramines being present in the water).
