The determination of glucose is possible with the enzymatic reaction of glucose oxidase and potentiometric detection. The signal is proportional to the concentration up to 50 mg/dl. This value is fixed by the concentration of oxygen in the sample. By adding catalase, concentrations up to 2000 mg/dl are detectable. The steepness of the calibration curve is not affected by oxygen concentrations greater than 4 mg/l. In contrast to amperometric sensors, an influence of deposits on the electrodes surface on the signal cannot be found with potentiometric sensors.
通过葡萄糖氧化酶的酶促反应和电位检测可以测定葡萄糖。该信号与浓度成正比，最高可达50mg/dl。这个值由样品中的氧气浓度决定。通过添加过氧化氢酶，可检测到高达2000mg/dl的浓度。校准曲线的斜率不受大于4mg/l的氧气浓度影响。与安培传感器不同，电位传感器未发现电极表面沉积物对信号有影响。
