*1: The max. load resistance is available within the range shown in the figure below, depending on power supply voltage:

Relation between power supply voltage and load resistance

*2: When the sensor cable, the transmission cable, or the contact input cable is extended to 30 m or longer, the surge test specified in the EMC directive for CE marking is not applied.


For transmission output, an arrester (spark-over voltage: 400 V) is implemented. However, use the optimal surge absorption element on the connection line in accordance with the ambient environment, equipment installation situation, externally connection equipment, and others.

  • This monitor detects the free fluoride ions in liquids, but it does not detect all fluorides. When complexes are present, a measurement lower than JIS will result.
  • Measurements may vary depending upon the pH level. Use this monitor in close to neutral pH conditions.
