can it check for PH for Hydrophonics

The TDS meter checks for dissolved ionic solids. Charge matter little. Positive or negative pH would give similar results. ie a pH of 9 would probably yield a similar TDS value as a pH of 5.

This device has no temperature compensation mechanisms. If I recall, it suggests that pH values should be measured at "room temperature," however vague such a statement is.

No don't do that . they have a cheap ph soil tester at lowes tests ph ,moisture and light thats what i use.

Not really. It's most useful for chlorine levels that are in the goal range for a pool. It does give a rough estimate of PH and CYA (a pool thing) content. Doesn't test for bacteria etc, and not even that precise at what it does measure.

Haven't used for home canning but I don't see why it wouldn't work. You have to be careful not to dip the tip too far into liquid (past the black cover) because the device is not waterproof. You also need to buy some calibration fluid to get accurate results. I bought ph4 and ph7 calibration packets to calibrate. They cost about a dollar a piece. This is not a bad tester considering the price. I have been using mine for a saltwater aquarium for a few months and it has worked well.

It cud b the temperature of your water and also u need to test your ph. Ph testing is really effective.

You can find out if the soil is acid or alkaline with the litmus paper but the litmus test will not indicate the degree of acidity or alkalinity. To determine the exact pH of the soil, you will need to use a soil test kit or even better take it to the local extension office and let them test it for you for free.

Have only used the ph strips to test saliva / urine as per box instructions. Don't know how u would test vaginal ph balance

I purchased this product specifically for testing the pH of water. It's actually a test for the pH of water for plants. I wasn't able to find another good product for specifically testing the pH of drinking water, so I got this one and it worked well for me. However, it isn't for testing urine. There are many products out there (usually strips) that are made specifically for testing the pH of urine. You can find pH strips for analyzing urine right here on Amazon and you can see from other user's feedback if they are good or bad. If you are still interested in possibly using this product I would go directly to the company and ask them your question since it's their product.

If you want to monitor your well water continuously, this pen will work, just make sure you calibrate it occasionally. If you just want a general idea of the pH of your well water, I'd go for a roll of pH paper strip.

No: range starts at 6.2-6.5. Get a ph meter, I did and works great. About $20 bucks on Amazon

The bottle says that the color code is light bluish for 8.5 and higer, so you probably wont be able to accuratly tell what the ph is if it higher. If your just testing regular things like your gardens water you will almost never get any reading that are higher than 8 or lower than 4 (or atleast i would hope so). Hope it helps a little!

i have only used them for testing drinking water and they do not work. the ph level does not change colors. you should go to a home depot type store and get a soil testing kit from their garden department. i should have returned this product but since i forgot too now it's wasted money.

yes just this. how ever you should also use "PH Calibration Solution (PH 4.01)" to ensure your pH pen is set right.

I don't calibrate the meter. It works right out of the box for humidity level. I do not use the ph meter or the light meter. May be you can stick in in vinegar and see if it reads about 3

Not sure what your question is. I use this instrument to test salt level in my aquarium. Too much salt add fresh water, too little do a water change. If mixing your own water make sure to use ro/di water and test for salt levels.

I tried it in liquids to see if it is showing the right numbers (vinegar vs water), but I am not sure if it is accurately shows the liquid PH.
