3M CTC331 IronMan Plus Monitor

The 3M (SCS) Iron Man Plus Workstation Monitor – model CTC331-WW is a compact ESD/EOS monitoring unit designed to protect sensitive electronics during soldering and assembly.

🔍 Key Features & Functions

• Overvoltage detection on PCB
  Monitors voltage between ground and PCB while working; alarms when voltage exceeds preset threshold (default ±5 V, adjustable up to ±50 V). Ideal for catching faults in soldering irons, tweezers, or improper grounding.

• Mat ground monitoring
  Ensures the ESD mat is properly grounded (resistance thresholds included)

• Alerts
  Visual (LED) and audible buzzer for each monitored function (PCB, wrist strap, mat)

🧰 Applications

• Electronics manufacturing and repair benches

• Sensitive component assembly (medical, aerospace, military)

• Anywhere static or overvoltage pose reliability risks
