本电导率电极系列把正确的电极常数匹配给正确的水体:K=0.01 用于纯水,K=0.1 用于低电导样品,K=1 用于一般与工艺水,K=10 用于高浓度液流。五个型号——HWS3023、HWS3022、HWS3000、HWS3021 与 HWS3010——覆盖从 0.2 uS/cm 纯水到 200 mS/cm 高浓度废水。
根据型号不同,外壳为不锈钢、铂金玻璃、石墨或铂黑玻璃;每支都带 NTC10K 温度元件,测量温度 −10–80 °C,外形 φ12 × 120 mm,配 1 m 电缆,适配 BNC 接口仪表。
K(电极常数)是什么意思?
K 描述电极对的几何结构。低 K 电极(0.01、0.1)适合低电导水体,能给出稳定的低值读数;K=1 与 K=10 适合一般与高浓度水体。选对 K 能让读数落在仪表精度窗口内。
纯水该选哪个型号?
0.2–20 uS/cm 左右的纯水与超纯水应选 K=0.01 型号(HWS3023)。更高 K 的电极缺乏如此低值所需的灵敏度。
系列能测多宽?
跨型号覆盖从 0.2 uS/cm 纯水到 200 mS/cm 高浓度废水——搭配兼容仪表时整套电极覆盖这个全谱。
这些是 CON200/CON600 之类的备用电极吗?
它们是用于兼容电导率仪器的独立电极。购买备用电极时,请确认电极常数与接头匹配你的仪表型号。
