I’ve waited and even measured the next day. I can feel the soil is still wet and it reads dry. I don’t get it. **Q: Can I put this item into the water to test the accuracy?** A: Please could not put this item into the water. Thanks! Here is some notes for your reference, thanks! -Don't measure liquids especially water, it is only used to test the soil moisture. -Choose a soft soil, forbid to force the metal probe into the hard soil. -Please don't put the probe pen for a long time in the soil (no more than one hour), otherwise it will damage the pen. -Don't use the measuring pen near the magnetic material and away from other metal objects. -Don't hold the metal part of the measuring pen by hand. Fingerprints have grease that reduces the accuracy of their measurements. -Don't try to remove the metal tip of the tester. If the tip becomes loose, tighten it clockwise. **Q: Can this be left permanently in a potted plant? Or must it be inserted and then removed each time I want to take a measurement?** A: It's not entirely accurate to say that it will "melt," but not far off. This device has no battery to insert, but the tip is of a different metal from the long sleeve. Likely the sleeve is copper or brass (a copper alloy), and the tip is probably zinc. When placed in moist soil, the two metals form a difference in electrical potential, essentially a battery. The electrical potential will corrode, dissolving the zinc tip over time. The same mechanism is used in ships, rocks, and bridges: they attach replaceable zinc electrodes to the steel, to make the zinc corrode instead of the steel. If you leave this in the soil, the corroding zinc from the tip will be electrodeposited on the sleeve, reducing the electrical potential, and eventually making the current stop flowing. You will then have to rub the zinc off the sleeve to make the meter work again. Over time the zinc tip would disappear. So, the answer is NO, you can't leave it place. You should get a reading, then remove it from the soil and wipe it clean and dry each time. ...and now you know WHY you have to do it. **Q: Can I use one to take readings on all my plants without having to leave it in** A: You have to insert it in the plant soil and it will give you the reading right away. You then can take it out and go to the next plant to get a reading. You only leave it long enough to get the reading then take it out. Do not leave it in the soil all the time. That's the way I use it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent, quality product *by S***S on 24 June 2026* Really useful tool, helps prevent over watering and killing plants ### ⭐⭐⭐⭐⭐ Water plants *by S***F on 7 July 2026* Seems to work ok, so far.watr ### ⭐⭐⭐⭐ A useful tool for plant care. *by A***S on 20 March 2022* The meter is easy to use and will take the guesswork out of plant watering. ## Frequently Bought Together - Dr.meter Soil Moisture Meter, Plant Water Meter for Garden Lawn Farm Indoor & Outdoor Use, Soil Tester Hygrometer Sensor for House Plants, Gardening Gifts, No Battery Needed - XLUX Soil Moisture Meter, Plant Water Monitor, Hygrometer Sensor for Gardening, Farming, Indoor and Outdoor Plants, No Batteries Required - Dr.meter Soil Moisture Meter Tester for Plants, Long Probe Hygrometer Moisture Sensor for Houseplants Indoor Outdoor Garden Lawn Use - Plant Water Gauge Test Kit - No Battery Needed - Gardening Gifts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/195966244-27cm-soil-moisture-meter-plant-watering-indicator-and-hygrometer-sensor](https://www.desertcart.jp/products/195966244-27cm-soil-moisture-meter-plant-watering-indicator-and-hygrometer-sensor) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-08*
