• Designed for dual-wire wrist straps
• Independently measures the resistance of both sides of the band for two operators and ground
• Visual and audible alarms trigger on grounding or mat connection loss, short, or open (high resistance)
• Supports 2 operators via 3.5mm dual wire ESD wrist strap connections, 1 each per remote box
• Monitors 1 ESD mat ground plane

Botron’s B92022 Continuous Dual Wire Monitor is designed for dual-wire wrist strap applications and monitoring resistance of both the work surface and the operator(s).

They come with a LED and a built-in audible alarm, triggered when either the operator or work surface falls out of spec, becomes disconnected, or ground is lost. These units can only be used with mono jack connectors. It is a fixed resistor system and is go no go, there is no calibration needed. ANSI S20.20 Compliant.
