The 597 is a complete Temperature, Relative Humidity and Pressure measurement sensor.

All sensing elements are of the highest quality and are specifically designed for continuous duty in hostile environments. The temperature sensor utilizes platinum RTD class 1/3B. Relative Humidity is a based on our very accurate solid state sensor design for continuous exposure to adverse climates. And the Barometric Pressure sensor is a piezo-resistive device designed for robustness, high accuracy as well as long term stability.

All components are housed in a Multi-Plate naturally aspirated Radiation shield to reduce solar radiation errors. The shield is constructed of a series of white aluminum concentric plates, which allow air flow to pass through the shield, while blocking direct solar rays.

Connectivity options are built-in and additional connectivity options are available with the 10600 Interface. The 597 has both analog and digital signal outputs for maximum flexibility. Analog outputs provide conventional connections to data loggers and systems utilizing a voltage proportional to each of the three measurements.

Digital outputs are present as a data stream every second, or upon command by the data system. The digital outputs have the advantage of higher resolution and immunity to analog offset problems.
