Overview
The Desco 19212 is a Jewel® Workstation Continuous Mini Monitor designed for ESD-sensitive assembly and testing environments. This single-station monitor provides real-time monitoring of operator grounding integrity and ESD mat connectivity with automatic alarm response upon detection of faults. It operates on 120/24VAC input and is calibrated to NIST standards for regulatory compliance.
Key Features
- Dual-channel monitoring: continuously tracks operator wrist strap and worksurface mat grounding
- Fast alarm response: audible and visual alerts activate in less than 50 milliseconds on strap failure or disconnection
- Path-to-ground detection: verifies grounding path resistance below 500 megohms
- NIST calibration: certified to NIST standards with included calibration certificate
- Compact Sapphire-colored design for easy eye-level mounting without consuming work surface space
