Desco 19662 Dual-Wire Dual Operator Monitor
Desco 19662 Dual-Wire Dual Operator Monitor
The Desco 19662 is a dual-wire, dual operator continuous ESD monitor — designed for facilities that require the highest level of wrist strap ground path verification. It simultaneously monitors two operators, each using a dual-wire wrist strap, providing real-time continuous verification of both the primary and redundant ground paths for each operator. Dual-wire wrist straps and monitors are required by some high-reliability ESD programs where a single point of failure in the ground path is not acceptable. The 19662 provides independent audible and visual alarms for each operator channel.

Key Features
- Dual-Wire Wrist Strap Monitoring: Monitors both the primary and redundant ground paths of dual-wire wrist straps — the highest level of continuous wrist strap verification available.
- Dual Operator: Monitors two operators simultaneously from a single unit — reduces monitor count in multi-operator work areas.
- Independent Alarms per Channel: Each operator channel has its own audible and visual alarm — a failure on one channel does not mask the other.
- Continuous Real-Time Monitoring: Verifies both ground paths throughout the entire work shift, not just at shift start.
- ANSI/ESD S20.20 Compliant: Meets continuous monitoring requirements per ANSI/ESD S20.20 and ANSI/ESD STM13.1.
Frequently Asked Questions
What is the difference between the Desco 19662 and the Desco 19655?
Both monitor two operators continuously. The 19655 monitors single-wire wrist straps — one ground path per operator. The 19662 monitors dual-wire wrist straps — both the primary and redundant ground paths per operator. The 19662 is required if your ESD program mandates dual-wire wrist straps for high-reliability applications where a single point of failure in the ground path is not acceptable.
Why would a facility use dual-wire wrist straps instead of single-wire?
Dual-wire wrist straps provide a redundant ground path — if one wire fails, the operator remains grounded through the second wire. Some high-reliability ESD programs (aerospace, defense, medical device) require dual-wire wrist straps and continuous dual-wire monitoring to eliminate single points of failure in the personnel grounding system. ANSI/ESD S20.20 permits either approach; the choice depends on the sensitivity of the devices being handled and the risk tolerance of the program.
Is the Desco 19662 compliant with ANSI/ESD S20.20?
Yes. The 19662 meets continuous monitoring requirements per ANSI/ESD S20.20 and ANSI/ESD STM13.1 for both operator channels independently.
