土壤pH电极SS-PH465(Ecotech)

产品描述：pH电极是一种玻璃电极，由三种不同类型的玻璃构成，适用于土壤。实际测量端由坚固、长期稳定的大壁厚膜玻璃组成。在玻璃膜和圆柱形玻璃轴之间增加了第三种玻璃(过渡玻璃)，其膨胀系数介于另外两种玻璃的系数之间，能够缓冲温度波动时产生的应力。

英文描述：

The pH electrode is a glass electrode which is constructed from three different glass types to be applicable in soils. The actual measuring tip consists of a robust and long- term stable membrane glass with a large wall thickness. Between the glass membrane and the cylindrical glass shaft, a third type of glass (transition glass) was added, whose expansion coefficient lies between the coefficients of the other two glass types and thus is able to buffer stresses occurring during temperature fluctuations.
