The Spartan One model CM300 is a One Operator Continuous Monitor that Ensures Your ESD Workstation is Static-Safe 

The Spartan Series Constant monitors provide ongoing testing of single wire wrist straps and ESD worksurfaces. The CM300 one operator continuous monitor not only eliminates time consuming wrist strap testing, it removes the danger of wrist straps failing in the field and possibly exposing highly sensitive materials to static. Both audible and visual alarms signal when the wrist straps fail. Enclosed in a durable metal case with built in mount-ing brackets, the monitors can be installed underneath table tops to save work space. The CM300 series monitors meet or exceed the recommendations of ANSI ESD S20.20.

  • Ensure ESD Protection: Ensure your ESD Workstation is Static-Safe by Continuously Checking One Single Wire Wrist Strap
  • Compatibility: Compatible with Most Standard Single Wire Wrist Straps
  • Alarms: Audible and Visual Alarms Indicate a Ground Failure
  • Ease of Use: Simply Plug in a Wrist Strap To Begin Monitoring
  • Factory Calibrated: It is a Fixed Resistor System and there is no Adjustments Needed.


 Why Use Constant Monitors

The first and best line of defense against static damage is wrist strap grounding, but these wrist straps wear over time and must be tested to ensure they are working properly. ESD Constant monitors reduce production costs by eliminating the time spent on testing wrist straps before each shift. Further savings may be realized by reduced ESD damage from broken wrist straps.

Capacitance Technology

The CM300 one operator continuous monitor sends out a signal through the wrist strap that detects the capacitance of the person and ground. When both are present, the monitor goes into an unalarmed state. If the electrical connection to the person or to ground should fail, the circuit will go into the alarm state to signal there is a problem.

The CM300 constant monitors are factory calibrated and will never need recalibration. It is a fixed resistor system and is go no go, there is no calibration needed. You can verify proper working conditions with the CM410PV  periodic verification.
