SISMOS-4
Magnetic Field & Vibration Survey System
ITEL portable, high-precision magnetic field and vibration survey system, specifically designed for pre-installation MRI site assessments and other high-sensitivity environments.
Measure First. Decide with Confidence.
Invisible Risks Can Kill an MRI Project
What you don’t measure can cost you everything. MRI systems, electron microscopes and high-precision sensors are extremely sensitive to environmental disturbances.
ENVIRONMENTAL THREATS
Low-frequency magnetic field fluctuations
Environmental electromagnetic interference (EMI)
Mechanical vibrations
Acoustic noise
What you don’t measure can cost you everything. These disturbances are often invisible during standard site inspections.

These Disturbances Can Cause
Image Artifacts & Instability
Site Rejection by OEMs
Costly Redesigns & Delays
Post-Installation Mitigation Expenses
SISMOS-4 Environmental Survey System
Professional site intelligence before you build or install
SISMOS-4 turns uncertainty into data — and data into decisions. Know if a site is suitable before installation, understand which mitigation is required, and provide engineering-grade data to OEMs and planners.
What it does
Measures low-frequency magnetic field disturbances
Detects vibrations and acoustic noise
Analyzes data in time and frequency domains
Identifies both slow trends and fast transient events
Why it matters
You know if a site is suitable before installation
You understand which mitigation is required (if any)
You provide engineering-grade data to OEMs and planners
