摘　　要：以聚四氟乙烯和纯金电极为主要材料,制成了一种成本低、操作简便的Clark型溶氧传感器,并将该传感器在不同温度下的淡水和盐水中分别进行了测试。传感器的响应电流和溶解氧浓度之间呈良好的线性关系,在溶解氧浓度0～8mg/L范围内,误差小于±0.4mg/L。A cost-effective and user-friendly Clark-type dissolved oxygen (DO) sensor is fabricated using teflon membrane and gold electrode,and the tests are made in fresh water and salt water under different temperatures.The good linearity between DO concentration and current of the sensor is revealed.Its accuracy is within (±0.4mg/L) in the DO range of 0 to 8mg/L.
