本款仪器是园艺的好帮手,可以测试土壤的PH值(酸碱度),无需电池,探头长度19.5CM。 使用方法: 先将探头尽量深地插到土里,探头上面部分留大约1厘米。测量范围8-3.5数值,ALKALINE是碱,ACID是酸,数值7基本是中性,数越小说明酸度越大,请根据植物的品种调整土壤酸碱度。 使用时注意插电极时不能碰到石头,不要用力过猛...
ConclusionPathological GER of term neonates mainly manifest as reflux of weakly acidic and liquid. 24 h MII-pH monitoring could detect weakly acidic reflux and weakly alkaline reflux, so it would be the recommended diagnostic tool for neonatal gastroesophageal reflux. Despite vomiting, special attention...
For standard ambulatory esophageal pH monitoring, a nasogastric catheter fitted with a pH probe is inserted through the nose into the lower esophagus. The catheter is attached to a data logger that is worn on the body. The catheter is left in place for 24 to 48 hrs. Over this period, the...

The PH buffer powder/calibration powder is used to calibrate the accuracy of the electronic PH measurement probe. The electronic PH measurement probe has high accuracy, but the test results will shift with long-term use. Therefore, the measurement probe should be ca...

8 The calciuria due to long-term acidosis can lead to bone demineralization. The plasma HCO3− increases immediately in response to an increase in Pco2 (Table 14-2). The immediate HCO3− changes are modest (4 to 5 mmol/L) and incomplete compared with those in response to a chronic ...

However, excessive cellular uptake of these reagents will not only disrupt cell viability but also compromise effective long-term monitoring. Here, we present a novel fiber-optic fluorescent nanoprobe with a high spatial resolution for label-free, subcellular pH sensing. The probe has a fast ...
