产品详情
[特征]
●HI 99121D是一种适合土壤测量的pH仪，是一种防水土壤直接pH/℃仪表，可让 直接将pH电极直接插入土壤中。与传统的水与水混合并测量上清液相比，这节省了很多时间和精力。此外，它还可以测量除土壤以外的溶液（液体），从而使其可用于管理水培种植中的养分液。
●包括一个螺旋钻（棒），以松开土壤。 (Please prepare separate soil conditioning solution, purified water, and distilled water to moisten the soil) ● Refill the internal liquid inside the electrodes
● Indication of the measurement stability mark indicates the timing of reading
● Hold button that can fix the reading value
● Automatic temperature compensation
● Can be d for approximately 1400 hours with three AA alkaline batteries
● Notify us on the screen when the remaining battery level is below 10%
● Comes with a convenient case for carrying
