二合一土壤酸度計和肥料計ETP303
本款儀器是園藝的好幫手,可以測試土壤的PH值(酸堿度),以及土壤的肥力，看是否需要施肥.無需電池.
使用方法:
測土壤PH值時,先將按鈕撥到PH，將探頭盡量深地插到土里,探頭上面部分留大約1厘米，指針對應的是PH值。
撥動筆上的按鍵到FERTILITY, 同樣對應著有三個檔：肥力不足需要施肥；肥力正好 ；肥力過多。
使用時注意插電極時不能碰到石頭,不要用力過猛,用完后把電極擦洗干凈。
Features
*Give accurate results of the PH and Fertility of the soil
*No batteries required
*The Ph portion of the tester utilizes the chemical reaction known as oxidation-reduction to measure PH within the range of 1-9
*The fertility portion of the tester measures the soil's nitrogen, phosphorous and potash (NPK) content, in combination. Fertility is within the range of too little, ideal and too much, with probe
