Submerged Liquid Conductivity Sensor Salinity TDS TEMP Meter For Water Testing

Online Conductivity And Salinity TDS TEMP Sensor Graphite Two-electrode Replaceable Probe Design

1.Product Introduction

The KNF-102PRO type conductivity and salinity sensor adopts the latest design sensor. Based on numerous on-site application experiences, it has undergone multiple upgrades on the original basis and is simple and convenient to use. The KNF-102PRO type conductivity design can be used for both pipeline installation (optional accessory: Y-shaped 3-way with end face seal) and submersible installation. When applied to pipeline installation, it can withstand a maximum pipeline pressure of 6bar, and the submerged installation can ensure normal use at a water depth of 50 meters. The conductivity adopts a 2-electrode working mode. The electrode material is graphite, which can effectively reduce the damage of polarization effect to the sensor. The unique circuit design enables the sensor to work accurately and reliably in a wide range of water bodies from 0 to 100mS/cm.
