Is this the right tool to test plant leaves for potassium levels?

This is to test human potassium levels. Not sure if you can use it for plants. I did notice there are some like this that is used for plants.

Yes, the meter can be used for this purpose. You would have to sample the leave's liquid matrix at various points on the structure but as long as your measurement locus is the same then the results should be the same. Time of day, maturity of plant as well as locus and soil/soil moisture should all be kept constant. If you modify any of these variables then that is your post sample condition. Get a baseline and confirm with multiple samples THEN start changing soil/water/maturity, etc.

With this meter you would have to grind them up and make a solution and then place a few drops on the testing strip. But just call the company and they will help you.

The reading is almost immediately and seems accurate so far. I have two of these on my outside plants but they are in pots. I think the ground would be different since it is a larger area, maybe for a quick check if you put it near a plant on the ground but I wouldn't leave it in the ground.

I honestly don't know, would think probably not, as this tests for chlorine too. Maybe do a search for saltwater test kits? I'm unfamiliar with what you need exactly, so sorry.

I don't have a light meter to test with, but I can tell you my plants have NOT done anything with this light. No positive or negative changes.

I am not sure if this can be used for salt water pool check. I recommend searching for "salt water test strips". I think you would want to check for sodium chloride levels which this product does not check for.

I use the tester to check the acidity in the water for my plants. I add lemon juice and vinegar (equal Parts) to raise the acidity in a five gallon bucket of water. So I will say yes to your question. The tester seems to work better in water than in soil. I hope this helps.

Yes I think so. You can call to check first Your plants won't know what happened! I love it.

The best way to check is to put your hand under it at the level of your plants. If the back of your hand gets warm after one minute, raise it up.

Hi Carla, Not sure if this is what you want. I bought it for testing the ph in our club kitchen dishes rinse water. Turns out this is the right one. 2 places to check for the right kind: local health department (they set me straight) and county extension agency. good luck

The HB-2 is a dual-function device that also measures for soil moisture and it's about $50 more expensive. If you just want a reliable, easy-to-use, rugged and accurate tester for acidic, neutral and slightly alkaline soil - something that covers the pH range of soils growing most crops & other plants - the PhD works perfectly. I've not used a HB-2 myself, but I'd assume it's an equally well-made device. Soil moisture is more of a concern to a farmer than a home garderner; which one is better depends on what you need it for.

This meter tells you the moisture content in as little as one inch of dirt, so it would work for most any plant. The probe tip diameter is the size of a large screwdriver so care must be taken to prevent damage to plant roots, but I would recommend it due to its quality construction

I use this meter for soil, there is a soil ph tip you can buy for it, I use the ppm tip for testing prior to feeding and the ph tip included prior to watering and feeding. Hope this helps

Gosh I add salt to my pond when I need to and stil use this test kit for the other tests I keep an eye on through out the summer. I hope this helps!

It is for the soil, I don't think it would be of any benefit to the leaves. It is made to condition the clay in the soil.

The clamp is not that accurate. I think its good for testing starters, alternators, etc. I just don't think it would it would work for trying to see less then an amps worth of difference. I wouldn't bother using it to measure anything less then 10 amps.

This test has several capsules for each test you want to run. My soil was really depleted. So I tested the first time to see what it needed, and then added those nutrients, and a week later tested again. I used the recommendations on the instructions to "fix" the soil, and it worked really well. The kit is easy to us. Read the FULL INSTRUCTIONS on the inside. The short version does not work. It will take a few hours or even days for some, because you have to put the soil in "purified" water, and let the soil settle to the bottom and the liquid become as clear as possible. I bought these on Amazon and if I remember right paid less than $10 for the complete kit. It was cheaper that way. I love these tests. Hope this was helpful.

yes,it test any water ph all u need is 1oz of water to be used before watering-very accurate.best for testing water ph from 5.0-8.0 in a test tube takes 10 seconds to do.
