室内の植物用に購入しました。 単4電池が4本必要です。 説明書は見ずとも土にぶっ刺してボタン押すだけなので直感的に使えるしバックライトもついてて見やすいです。 右のボタンを長押しで電源オフできます。 光量計測もできますが上限が9999ルクスなのでアガベなどのがっつりライト当てて育てるような植物には使えないですね。 パネルライトつけたら一瞬で上限いったので感度はよさそうです。

大変使いやすい。ただし、取説が英語であることが難解。

バラの小さい鉢から大きい鉢の約30鉢などの水やり管理は、表面が乾いたら、たっぷりと水を与える管理をするようにと言っている人達が多いが、どうもうまくいかない。そこで、アナログ的管理ではなく、デジタル的管理にしようと思い、本製品を購入しました。 すると、今までの水やり管理が間違っていたことがわかりました。 左手測定器、右手にホースを持って、瞬時に測定結果が表示されるので、水分値を確認してから、個々の鉢の水の量を調整しながらお世話できるようになりました。今年の春の満開が楽しみです。

説明書が英語で困ったと書いてありましたが 難なく使えました

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!

不良品だったみたいです。 どこを測定しても同じ数値。 未調整のピートモスも草花培養土も庭土も全て同じ数値。 わざわざ高いデジタルの方を買ったのに。

デジタル表示見やすいEnglish版のみなので、解読がめんどう。

定植圃場の潅水管理の為に水分量を計測したくて購入。正確かどうかはその他水分計と比較していないのでわかりませんが、乾いた圃場、潅水後の圃場で計測結果は変わるので目安として使えそうです。

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. .

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.
