Model 4500CR Series

Model 4500 Corrosion Resistant Piezometers and Pressure Transducers are designed for use in chemically aggressive environments, such as mine tailings, leach pads, and marine applications, where standard vibrating wire piezometers may not be particularly suitable, especially for long-term monitoring. The main advantage of the 4500CR Series over the standard piezometer lies in the corrosion resistant materials used in their construction. Versions manufactured from INCONEL® (Model 4500INCO) or Titanium (Model 4500Ti) are available. Both models incorporate enhanced seals at the cable entry and filter connection*.
