3M ESD Pro Event Detector can detect and display the strength of electrostatic discharge events, helping you assess the ESD environment and determine whether the production environment is suitable for handling ESD-sensitive devices.
The 3M CTM082 ESD Pro Event Detector is a hand‑held instrument that locates and identifies electrostatic discharge (ESD) events in manufacturing and other environments. It counts discharges, shows their relative strength with an LED bar‑graph, and provides an audible alarm when a set threshold is exceeded. The device also rejects most non‑ESD electromagnetic interference using a proprietary CDM mode, making it suitable for noisy settings such as electronics assembly, semiconductor manufacturing, and medical or aerospace applications.
The manual describes the detector’s features, adjustable alarm threshold, four‑digit event counter, power requirements, and mechanical dimensions. It also includes ordering information, warranty details, and guidance on using the detector for ESD diagnostics, equipment evaluation, and tool qualification.
