土壤pH直测仪

土壤直接测量pH笔

型号:PHDS2-N

现如今，有史以来第一次有一个pH笔，可以直接在土壤样品上提供土壤pH值读数，无需混合浆液。只需将土壤样品从地下取出，将pH直测笔的平面电极置入土壤中并读取数值。土壤pH直测笔还可以测量液体的pH值，可以读取和记录15个连续数值，具有自动温度补偿功能，并可以同时显示pH和温度值。仪器配有平面pH电极、传感器保护盖、冲洗瓶、电池、4.01和7.01pH校准液。单位精确到+/-0.10pH。

Direct Soil pH Pen

Part#：PHDS2-N

Now, for the first time, there is a pH pen that gives soil pH reading directly in a soil sample without having to mix a slurry. Simply pull a soil sample out of the ground, press the Direct Soil pH Pen's flat surface electrode into the soil and read the meter. The Direct Soil pH Pen also measures pH in liquids like irrigation water and spray tanks and unit even floats! Memory records and recalls 15 sequential readings, has automatic temperature compensation and displays pH and temperature. Complete with flat surface pH electrode, protective sensor cap, rinse bottle, batteries, 4.01 & 7.01 pH calibration fluid. Unit is accurate to +/- 0.1 pH point.
