概览

Campbell Scientific的CS525 pH值探头提供了可靠的精确的pH值测量，在整个工作温度范围内都实施补偿。该探头通常测量水媒的或半固态溶液的pH值，探头可以被浸入或插入水箱、水管或开放水渠中。

优势与特点

  • Compatible with the CWS900-series interfaces, allowing it to be used in a wireless sensor network
  • Electronics are safely embedded in a durable resin body
  • Elimination of the glass-bulb makes the probe more durable and safer to use
  • Fully temperature-compensated
  • Innovative ISFET pH-sensing element used as measurement electrode
  • Designed and manufactured under stringent quality control conditions in an ISO 9001 environment, ensuring good measurements
  • Each sensor individually tested
  • Compatible with all contemporary data loggers (including the CR200X series)

技术说明

CS525采用SENTRON的高科技的离子敏感场效应晶体管（ISFET）半导体作为它的pH感应元件，并且包含 银/氯化银-氯化钾参考系统。ISFET技术是当今最强大的pH监测技术，它相当程度地减小了极端pH条件下的酸性或碱性的数值误差。CS525可以监测含有高固体组分、腐蚀性化学品、或者容易阻塞或污染传统的玻璃泡pH计的生物体的液体的pH值。

CS525的耐用设计，使得它适合任何液体的pH值监测应用，从实验室到严酷的野外应用。探头的电子单元安全地封装在耐用的PEEK外壳里。不需要玻璃泡，也消除了玻璃破碎的可能性，使得CS525更耐用更安全。

Note: CS525-L ISFET pH值传感器在接地环路和流电条件下高度易受影响。克服该问题的最好隔离技术是使用CWS900系列无线传感器接口。在很多情况下，CS525也可以实现隔离，通过不接地到数据采集器，从而连不到大地。请在订购传感器之前与Campbell Scientific应用工程师讨论您的应用。
