• Part number B92900
• Two person continuous monitoring system
• Measures the ESD device and human body down a 2 conductor path to ground
• Provides a more accurate reading than resistance loop monitoring
• Displays the actual resistance level of your work surface grounding path - not just pass/fail

Total path to ground measurement is the apex of wrist strap constant monitoring. In contrast, resistance loop monitoring ignores the most vital part of an ESD control program, the total resistance of a system. The Sentinel V2 measures the ESD device and the human body down a 2 conductor path to the ground. This circuit differs from resistance loop monitoring in which the measurement is calculated with device resistors in a parallel path, halving the resistance for a truer, more accurate reading.

The Sentinel empowers you and your team to mitigate risk, direct corrective actions, reinforce learning, and better identify improvement opportunities more quickly and accurately.

Total path to ground

The Sentinel’s one-of-a-kind design is the first monitor to accurately display the resistance of the operator to the ground.

Total resistance to ground paints the picture from your point of view, as the operator, the source of voltage. The resistance equivalent of your dual conductor wrist strap is actually 500kR, a parallel path to the ground, and this is how the Sentinel reads it. Conversely, all other wrist strap monitors measure each side of the wrist strap in series, for a total wrist strap resistance of 2MR, which is incorrect.

The Sentinel doesn’t just monitor your wrist strap, it transforms it into a sensor, monitoring your grounding condition as you interact with your local environment, detecting not only exposure to ESD but safety hazards that may put you or your personnel at risk.

Hardware, hand tools and soldering stations can all transfer harmful voltage into your assemblies. Two Circuit Intrusion Monitoring ports (CIM), are designed to detect voltage events on assemblies or even voltage buildup on tools, like soldering iron tips.

The ELITE WebUI is a web app baked right into your Sentinel device. It makes setup, configuration and customization super simple. You can access Sentinel's ELITE WebUI anywhere on your network, from any device, be it mobile, tablet or desktop.

Variable total resistance technology provides complete and total control over the hardware. With no feature more paramount than a 100% adjustable monitoring circuit. Adjust your high and low fail ranges anywhere you wish, from 750k to 40M Ohms. CIM monitoring, anywhere from -35V to +35V. This means you aren’t stuck with what the manufacturer says is best-do what's best for you and your operation. This is what Botron refers to as Application Based Controls. One device, that can be as sensitive and strict as you need in one area, yet in another, as general as ESDA standards.

Live View can show you a number of things. The current results from your operators, fault counts from connected tools, and mat voltage are just a few. You can view this in real-time from a network-connected device, anytime and anywhere.
