SURVEYOR PLUS™ Environmental Condition Monitor Silver & Copper Corrosion Sensors Features: • Corrosion Rate, Relative Humidity, Monitors Temperature, and Differential Pressure • High-Sensitivity Corrosion Rate Measurement • Corrosion Rate of Copper and Silver Sensors Corresponds to ISA Classification of Environments • Digital and Analog Outputs • Optional Datalogging The SURVEYOR PLUS™ is a multiparameter monitoring system providing constant surveillance of the environment and rapid detection of any deterioration that could result in damage to expensive equipment and valuable assets. Early detection of humid, high temperature, or corrosive conditions will permit corrective action to be taken before substantial damage occurs to sensitive computer and instrumentation systems or electrical equipment. correspond to the ISA classification of environments (G1 through GX) for copper and silver. The system measures humidity, temperature, and the corrosive attack on two replaceable thin-film sensors. The corrosion rate is shown by indicator lights that The SURVEYOR PLUS™ is particularly useful for environmental monitoring in refineries, chemical plants, pulp and paper plants, control rooms, computer rooms, museums, and clean rooms. Analog and/or digital outputs of corrosion, humidity and temperature information provides remote alarming, display and recording. The information may also be stored in the on-board data-logger, and accessed via PC software. The system can also be used as a highsensitivity corrosion monitor for special applications.
