Dual Wire Wrist Strap provides redundancy; even if one dual wire wrist strap
conductor is severed, operator has reliable path-to-ground with other wire.
•Used with resistive loop technology continuous monitor, continuously verifies the
proper resistance to ground of the operator
•Comfortable adjustable wrist band made of silver suffused monofilament
conductive interior
•4mm snaps are machined to precision profile from 300 series stainless steel for
a consistent and reliable connection. 7mm snaps are stamped.
•304 stainless steel back plate
•Woven Silveron™ fabric infused with silver monofilament conductive fiber is
comfortable and hypo-allergenic
•Patented* dual wire technology
• Superior resistor connection strain relief
Superior reliability. Greatly exceeds ESD S1.1 Bending Life Test. Tested at over
200,000 cycles vs. the 16,000 requirement
•Superior warranty - See details of 1 year Limited Warranty at
http://www.Desco.com/Warranty.aspx
•Superior quality product Made in America at our Chino CA facility

"If any part of the loop should open (become disconnected or have out of limit
resistance), the circuit will go into the alarm state" [ref TR20.20], nonetheless,
due to the redundancy inherent in the dual wire wrist strap design, the
operator will continue to be grounded via the second intact wire.
Per ESD Handbook TR20.20 section 5.3.9.2.2 Dual Conductor Resistance
Continuous Monitors, "This type of monitor is used with a two wire (dual
conductor) wrist strap. The wrist strap assembly consists of a two-wire ground
cord and a wristband that has two isolated halves. When a person is wearing
the wrist strap properly, the monitor measures the loop resistance consisting of
one wire of the ground cord, one-half of the wristband, the person's skin, the
second half of the wristband, and a second wire in the ground cord. If any part
of the loop should open (become disconnected or have out of limit resistance),
the circuit will go into the alarm state.
ESD Handbook TR 20.20 paragraph 5.3.2.4.4 Test Frequency "Because wrist
straps have a finite life, it is important to develop a test frequency that will
guarantee integrity of the system. Typical test programs recommend that wrist
straps that are used daily should be tested daily. However, if the products that
are being produced are of such value that knowledge of a continuous, reliable
ground is needed, and then continuous monitoring should be considered or
even required"
Continuous Monitors pay for themselves improving quality, productivity,
eliminating wrist strap daily testing and test result logging. Per ESD-S1.1
paragraph 6.1.3 Frequency of Functional Testing "Daily [Wrist Strap] testing
may be omitted if constant monitoring is used."
