Buying guide — how to pick the right EAS tester
- Frequency support: Match the tester to your system type (RF 8.2 MHz, AM 58 kHz, EM, or mixed). Buying the wrong frequency is the most common mistake.
- Diagnostic needs: For root-cause troubleshooting choose waveform/logging-capable units (e.g., SecureScan WaveAnalyzer). For daily checks, pocket testers suffice.
- Portability vs. features: Larger testers offer more features; pocket testers offer convenience.
- Battery life & durability: Consider field conditions and length of service calls.
- Accessories & support: Test tags, directional probes, calibration certificates, and vendor support can save time.
- Budget: Balance between feature needs and cost. A mid-range multi-band tester often offers the best ROI for mixed environments.
Practical tips for using EAS testers
- Calibrate periodically and keep a calibration certificate if required by your audit policy.
- Test across the entire portal width and multiple heights — detection can vary across the arch.
- Use known good test tags and deactivated tags to verify both detection and deactivation functions.
- Log intermittent failures with timestamps and environmental notes (nearby electronics, shelving changes).
- When measuring range, note store layout changes (mirrors, metal fixtures) that can affect performance.
Maintenance & safety
- Replace batteries per manufacturer guidance and inspect connectors for corrosion.
- Avoid exposing testers to extreme moisture or direct impacts.
- For antenna tuning and high-voltage components, follow lockout/tagout and manufacturer safety instructions.
Final recommendation
For most in-house teams and service providers in 2025, a multi-band tester with logging (examples: ProScan EAS-9000 or ShieldTech MultiBand) offers the best balance of flexibility and diagnostics. Smaller stores will benefit from a portable pocket tester for quick floor checks, while audit-heavy environments should invest in calibration-grade tools like the CalibraCheck S-200.
