Orion 611型pH/毫伏计是最近出现的一种新型PH计,它和一般常见的pH计相比,在设计上有很明显的特点。如所周知,根据能斯特公式,pH的测量,以及各种离子选择性电极电势的测量,和被测溶液的温度有密切关系。为了消除温度变化所引起的误差,过去或者在用温度计测量溶液的 The Orion 611 pH / mV meter is a new type of pH meter that has recently appeared which is clearly designed to be compared to the more common pH meter. As we all know, according to the Nernst formula, the pH measurement, as well as a variety of ion-selective electrode potential measurement, and the measured solution temperature are closely related. In order to eliminate the error caused by temperature changes, in the past or with a thermometer to measure the solution
