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.
