Review: Has kept my plants thriving for 10 months. - Got this 10 months ago and used every Sunday on my houseplants, which are doing fine. If in the moist zone, I leave for another week: in the dry zone, I water. I think I chose this one because it appears identical to the one sold by the RHS, but without the Dr Meter Branding. Review: One device for all your plants - Great piece of equipment, I hadn't realised that you shouldn't leave it in the soil, I was going to order more for other plants but on reading the information more carefully realised you use the one device for all your indoor plants. Fortunately 10 days in the soil doesn't seem to have corroded the device! Lesson learned, read the instructions and don't assume! ## Features - 【Compact & Portable】 Have you been sticking your finger in the soil hoping to feel when it's time to water?

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 ### ⭐⭐⭐⭐⭐ Has kept my plants thriving for 10 months. *by J***Y on 13 May 2026* Got this 10 months ago and used every Sunday on my houseplants, which are doing fine.
