Desco 19239 Mini Monitor, North America
Desco 19239 Mini Monitor, North America
The Desco 19239 Mini Monitor is a compact continuous wrist strap monitor for single-operator ESD workstations — providing real-time, uninterrupted verification that the operator's wrist strap and ground path are intact throughout the work shift. Unlike periodic testers that only check at the start of a shift, the 19239 monitors continuously and alerts the operator immediately if the wrist strap or ground connection fails at any point during work. Designed for North American power (120V), it is one of the most compact continuous monitors available for space-constrained workstations.

Frequently Asked Questions
What is the difference between a continuous monitor and a periodic tester?
A periodic tester (like the Desco 19280/19282 combo testers) checks wrist strap and footwear resistance at a single point in time — typically at the start of a shift. A continuous monitor like the 19239 verifies the wrist strap and ground path integrity in real time throughout the entire work shift, alerting the operator immediately if a failure occurs at any point. ANSI/ESD S20.20 allows either approach, but continuous monitoring provides a higher level of protection for sensitive devices.
Does the Desco 19239 work with dual-wire wrist straps?
The 19239 is designed for single-wire wrist straps. For dual-wire wrist strap monitoring, consider the Desco 19662 Dual-Wire Dual Operator Monitor or the Desco 19655/19656 Dual Operator Monitor series.
Is the Desco 19239 compliant with ANSI/ESD S20.20?
Yes. The 19239 meets continuous monitoring requirements per ANSI/ESD S20.20 and ANSI/ESD STM13.1.
Can the Desco 19239 monitor the mat ground as well as the wrist strap?
The 19239 monitors the wrist strap and operator ground path. For simultaneous wrist strap and mat ground monitoring, consider the Desco 19336 or 19337 Multi-Mount Continuous Monitor, which monitors both the wrist strap and the worksurface mat ground connection.
