土のPHがすぐわかり助かりました。

とてもよい

難しい冬の間の水やりが「勘」に頼らず数値で確認出来るので間違いをおかさず安心してお世話できます！日本語の説明は無いですが電池を入れてスイッチ押したら誰でも分かります(笑)表面では無くしっかり奥まで差し込んで水分量を測れるのも嬉しいです！

取り説が横文字で分かりません日本語訳も添付してください。二度と買いません。

水分量が見れる物が欲しかったので、表面が乾いていても真ん中から下は50%以上あったり、見た目では分からなかったので良い買い物でした。オンオフが無く、勝手に電源が落ちる商品です。

説明書に日本語表記がなくわかりづらい

As this is my first time taking care of plants — my Mammillaria Spinosissima and Anacampseros 'Sunrise' — I wanted to be very careful not to overwater them. This 4‑in‑1 moisture meter has been really helpful; it lets me check the exact moisture level in the soil so I only water when it’s in the right range. The only things I would mention are that the device itself is quite large, and the probe feels a bit fragile. It would be great if they made a smaller version that can stay placed right beside small pots and give readings anytime. Also, please be careful when inserting it: I didn’t move the stones in my pot the first time, and it scratched the metal rod. Other than that, it works perfectly for keeping my little plant babies healthy!

Works well

This is the only digital soil meter on the market. All others utilize a magnetically operated needle, that swings in front of 3-to-5 scales. As a result, the user gets rough estimates instead of actual numbers. . It is also one of the few that requires battery power to operate. An electric charge is emitted into the soil and is received in the probe. A circuit board measures the tiny changes and reports the results in digital form. Many competing devices use no batteries. I wonder how their diagnoses work without electricity? . I took the meter to task on the first day. The initially readings were off. AMBIEN LIGHT measured 0, although the meter was under a grow lamp. SOIL MOISTURE measured 95% - very wet, although the dirt was only moist. . After a "break in period" of one day, I tested again on the second. The features proved accurate. On the TEMPERATURE feature, I measured room air. The temperature was 1F higher than my oven thermometer and room thermostat. . . . Excellent! . To test the PH feature. I wet a face towel with water. It achieved a 7.1 reading - neutral. Water was neutral. . . . . Then, I wet a spot on the fabric with vinegar. The reading was 6.0 - slightly acid. Although vinegar was 4% acetic acid in distilled water, I expected a strongly acid reading. So, the PH feature was off by a half notch. . The MOISTURE feature worked to perfection. It measured the potted soil at 20% - dry. Examining the dirt, the moisture held the dirt in clumps, but it was relatively dry. . The AMBIEN LIGHT feature was good. Three grow lamps shined on my 10 juniper seedlings in pots. Each light source had a 100 watt grow bulb, with a 1700 lux rating. Putting the meter under one, it measured 2640 lux. With the added indirect light from the two other lamps, the reading seemed correct. . In the past month, I purchased three other competing soil meters and returned all. They tested grossly inaccurate, or some of their features were inoperative. . On this product, the features worked to perfection, except for PH - half correct. A second problem was missing the ability to measure FERTILITY. A third problem was the small text on the screen for TEMPERATURE and MOISTURE readings. They were very small. Other than these three shortcomings, I ranked it the best among the many soil meters available on Amazon. . . ------------------------------------------------------------------------------------------------------------------------- . . UPDATE: After two months of usage, the unit became non-functional. First, it no longer showed moisture. Second, one-fourth of the LCD screen went blank. . I contacted the vendor for warranty repairs/replacement. Within an hour, it responded with a request for a video of the unit in action. In compliance, the unit was turned ON. The regular screen appeared, indicating NO PROBLEMS. .

Really good product

Ce testeur 4 en 1 est exactement ce qu’il me fallait pour mieux comprendre les besoins de mes plantes. Il est à la fois simple à utiliser et très complet ! ✅ Les points forts : Lecture claire sur écran LCD : l’écran est bien lisible, même en plein soleil. On voit en un coup d’œil les 4 données essentielles : humidité du sol, température, pH et intensité de la lumière. Multifonction : j’adore pouvoir tout mesurer avec un seul appareil ! Ça m’aide vraiment à ajuster l’arrosage, vérifier si mes plantes reçoivent assez de lumière et même tester l’acidité du sol pour les plantes plus exigeantes. Facile à utiliser : on insère les sondes dans la terre, on appuie sur un bouton, et hop, les mesures s’affichent. Aucun calibrage compliqué ! Idéal pour intérieur comme extérieur : je l’utilise autant pour mes plantes d’intérieur que pour le potager, et les résultats sont cohérents et utiles. Léger et portable : facile à transporter d’un coin du jardin à l’autre sans s’encombrer. Ce petit outil m’a permis d’éviter des arrosages inutiles et de mieux comprendre pourquoi certaines plantes ne se développaient pas comme prévu. Un vrai allié pour le jardinage, que vous soyez débutant ou passionné.

Easy to use and easy to read. Valuable tool in my greenhouse.
