Luster Leaf 1825 Moisture Meter. Is it accurate

The needle moves according to how much 'electric current' flows through the metal wand. Essentially, water is the conductive substance. If the soil is dry, no ions can pass anywhere and the needle will not move, so it is dry. The more water, the easier for ions to pass and that makes the meter get its' power. This is more than adequate accuracy for plants. If this were ultracritical and you needed a specific readout of the percentage of water, etc. this isn't the unit. For everything else, it is a winner.

Hey Ray, as this is not what the tool was designed for, the results would be unreliable at best. That said, this tool does a very good job at measuring even small levels of moisture in sheetrock and wood. If you only have a small section of carpet, best bet is to tear it out and put new in. Carpet is cheap compared to mold problems that might come along ifeven a small section remains wet under the carpet.

You would need a know amount of moisture to check calibration that low but maybe. Its more for restoration work above 15%.

It will check the moisture in most anything. The question would be how to interpret the reading. In other words, for a dirt / gravel road what reading would be wet vs. dry. It comes with instructions for measure the moisture for plants, trees, etc. Not sure about your application. Might want to contact the manufacturer.

I found it to be accurate. Keep in mind that I use it to test grapes for ripeness, so I randomly sample. However, over the span of 4 weeks, the readings consistently increased, over the course of 8 samplings as the grapes ripened. I hope this helps.

it's a good indicator of relative soil moisture levels but i doubt if it's accurate enough for science

In my experience it is done taking the reading in around 20 - 30 seconds but I didn't have a good experience as my readings were all wrong. I know this because every plant I put it in even the crusty dirt plants got the same "wet" reading. I returned mine and am using the finger method which is 100% more accurate and free! You aren't supposed to leave it in the plant.

I noticed the same thing, it reads higher than the bayer one I have also by 20 points. This meter is a piece of junk in my opinion, wastes lots of strips.

I can't speak to "accuracy", as I don't have access to an analytical grade scale to verify the reading on the Gem Pro. But i can speak to repeatability. I put small amount of Red Dot on my scale and it read 2.72 grains. I reweighed the same sample 10 times and got eight readings at 2.72 and two readings at 2.74. I'd say that is pretty darn good. One thing I do is re-tare often, usually before weighing each sample.

I have a caliber IV hygrometer for a humidor which performs very well. To calibrate mine I followed the instructions and removed the activator tab.

I gave this as a gift to new parents. However, the new mommy told me that her hubby was using it to read the temp of things all over the house. Not sure how accurate the readings are on these other surfaces. Can you contact the manufacturer just to be safe?

Yes, you should be able to use this General Tool for what you need. I bought this moisture meter because I am a Home Inspector and Environmental. I am very happy with this moisture meter. Good luck.

I returned this product as it did not perform as specified. Humidity readings made by this unit are not correct, as verified by an independent humidity monitor placed in room unit operated in.

Sorry for your affliction. This machine seems as advertised. I got a couple of hygrometers to measure the humidification and it helps, but it was also summer/air conditioning season. I'd withhold judgment until I got through a winter with the dry heat of my electric furnace.

what parameters does it actually measure ??? does it measure ph and ppm or is it just a moisture and light sensor?

mine doesn't have moisture inside! i wouldn't buy this one tho. the guy tried to take 500 dollars out of my account, and yesterday it stopped working. I've only had it for like a month or so.

I bought this Tuscany canister set, as well as the bread box in mid January. I haven't had any moisture problems. I live in northern Maine and heat with wood so the air in my house is dry and I use a humidifier. Let suggestion would be to check the humidity level in your house.
