Will this meter check nutrient levels accurate of hydroponics? There is no temp change to worry about.

It only measures total dissolved solids, as gauged by electrical conductivity. If that will help you with nutrient levels, great, but I suspect the answer is really no.

No, it is just to check purity or cleanliness level. It doesn't tell anything else.

Yes, I am sorry to say. I did the same thing and had the same results. Also, let me warn you about getting the electronic , electric meter reader, I paid $22.00, for one, and it was so complicated I took it back to the store. The Etekcity works wonderful and is so easy to use. I have been using one for years to check the correct moisture and my plants look like florist plants, Don't forget to fertilize monthly or by the instruction on the plant. good luck

In order to calibrate such a probe, the manufacturers would have to add a calibration potentiometer to the circuit. Without opening up mine I doubt it was made for field calibration. You can test the accuracy of the device by filling a 8 oz glass with ice and water. Allow to set for 3 to 5 minutes and insert the probe. That water ice mixture should be 32 deg F. what your device shows should be considered where 32 is. That means if your device shows 29 you are off by -3 deg. this should not be a big deal a plus or minus 2 degs. Also, as the battery degrades, it will affect accuracy. Test your probe once a month and replace battery based on any drifting away from what you started out. I have used these types of probes for many years in hvac and they fail long before I lose accuracy.

No. This only tests for ph, ammonia, nitrite, nitrate. You can get a cheap hydrometer here on Amazon. Just do a search for it.

This meter's pH scale doesn't vary much above and below 7.0. Most people have a liquid available at the store they can use to do a quick check, distilled water, which under ideal conditions should have a pH of 7. If the scale is off by even a factor of .5, it could really hurt your plants.Some basic chemistry calculations: Kw = [H+][OH-] = 1x10^-14 at 25°Cfor pure water [H+] = [OH-] = 1x10-7Acidic Solution: [H+] > 1x10-7pH = log10[H+]Basic Solution: [H+] < 1x10-7When calculating pH, remember that [] refers to molarity, M.

The meter is very simple. A needle lies on to of a "meter?" and the meter runs from 0 to 10.The needle tells you the moisture in the soil.Seems accurate.

I have no clue, but would assume so, as it was recommended by my local hydroponics store. I have really good water, and so far have had no need to use Up or Down, just the test kit. Best way to find out if it's food grade is to email the mfr, General Hydroponics, at: email: info@genhydro.com Good luck, Mac

Yea its pretty accurate i use mine every day it comes with 2 bead probes i bought 2 pipe clams for measuring super heat and sub cooling make sure to calibrate before using

Yes. I bought it specifically to start cycling an aquaponics setup which requres ammonia without any additives besides water.

temp probe is very accurate to a tenth degree. don't if it's unique to the unit but then You don't need another one.

Cannot answer your question exactly but suggest you look at the following link - https://www.youtube.com/watch?v=ZoeUgMFLyAw.It will give you a GOOD insight. For my use the meter is adequate.

I bought the meter to judge the level of lead-acid batteries, but since it is just a voltage meter, I'm not sure it would make any difference.

pH on this meter is 0-8. no calibration needed, just cleaning with pad before use.

I sure don't! I bought this one and a Sun Master digital and they couldn't read further apart! What we need to find is a calibration solution that works on soil meters, not just water meters.

No. This meter is not a process meter. Process meters have an accuracy of about 0.2% for the 20mA range, this one is 1.5%. There are a few more detailed reasons, but to do any sort of instrument work you need a process meter like a Fluke 789 or an Extech PRC.

One could worry about the exact accuracy of this device, where I feel it is more a relative reading, and tells you the approximate amount of solids remaining in the water. For the most part, after filtering the water, the ZeroWater device reads zero.

No. I do not know of any 100% organic hydroponic nutrient solutions. There may be some out there, but I don't know. I do try to use organically when I can, but I worry much more about non organic pesticides than non organis fertilizer. This is a good product. Check out MHP gardener on YouTube. He has some excellent videos and uses this stuff for all his hydroponics.
