Botron B9203 Continuous Monitor (2 Operators & 1 Mat)

Your Price: $130.00
  • Buy 5 for $125.45 each
  • Buy 10 for $121.55 each


The Botron B9203 is designed to monitor resistance of both the work surface and the operators. It comes with a built in audible alarm and LED, triggering either when either the operator or work surface falls out of spec, becomes disconnected, or ground is lost. It is a fixed resistor system and is go no go, there is no calibration needed. A full time monitoring system is necessary to reduce latency on the assembly line.

To be used in work environments in accordance with S20.20 standard for monitoring resistance from worker to ground. It is recommended to use constant monitoring in work environments handling components that are more susceptible to ESD damage.

All Botron continuous monitors part numbers do no need to be calibrated. They are a go/no-go solid state, impedance based, monitors with no adjustability and does not need to be calibrated. It is always important to make sure that all units have a proper ground. An improper ground or poor connection will sound the alarm.
