Model 4500HHT Series

The GEOKON 4500HHT Series High Temperature Pressure Transducers are designed for monitoring downhole pressures and temperatures in oil recovery systems and geothermal applications, where the temperature may be as high as 250°C. These sensors are supplied with either mineral insulated cables, or with tubular encapsulated cables (TEC) inside stainless steel tubing.
