Features
A hand-held meter used to test the performance of ESD floors in combination with a person per ANSI/ESD STM 97.2. and IEC Standard 61340-4-5.
The electrostatic charge of a person walking on an ESD safe floor with ESD safe footwear can be measured with the EFM51WT Walking Test Kit. This test provides measurement data on the actual charge on a person while walking which is used to determine the effectiveness of the floor/footwear grounding system.
The EFM51 holds the PEAK value of the measured body voltage, as well as the LIVE static voltage measured on the operator’s body.
The kit includes the EFM51 static field meter, walking test adapter plate, hand probe and conductive carrying case. The EFM51 is a fully function field meter that in addition to the Walking Test, measures and detects electrostatic fields, surface potentials and discharge times (with optional charge plate accessory – p/n 7100.EFM51.CPS.SET.)

How to Use
Prepare the Field Meter
- The electrostatic field meter should be placed into the grounded foam base that is on a flat surface near the floor to be tested.
- Hold the function button until “change mode” appears. Press the button until “Max Value” appears (This is 6 button presses). This mode will become active in 2 seconds.
- Hold the probe in one hand and perform the walking test:
The operator walks on the floor section in a six-step pattern and comes to rest with both feet on the floor specimen in front of the EFM meter. The step pattern requires forward and backward steps and a cross over step:
Perform the test three times and record the results.
Reading the Meter
- The upper display line indicates the maximum positive and negative body voltage generated on the person when walking.
- The lower line indicates the minimum body voltage on the person.
Understanding the Measurements
Two sets of measurements are obtained during the procedure. The first measures voltage generation during the walking cycle and is defined as the Maximum Body Voltage. The second measures the voltage obtained at the end of the cycle with both feet on the floor specimen and is defined as the Minimum Body Voltage.
What Clients are Saying
StaticWorx has been an extremely valuable resource for helping to evaluate and specify ESD flooring to our team. On a recently completed project, consisting of 30,000 SF of microelectronics lab, our team worked with StaticWorx and President Dave Long to create the perfect ESD flooring solution for our client–blending required performance (both in terms of static control and highly sought after comfort on foot), aesthetics, and cost. The research and technical resources that StaticWorx provided helped to inform our team and client of the pros and cons of various ESD flooring solutions, and ultimately, guided in flooring specification and use. StaticWorx is a proven leader in static control flooring solutions–our interactions with their team members, and most importantly, their product performance, is a testament to that fact!
We appreciate Dave taking the time to travel to Savannah to share his extensive technical knowledge of static control flooring and practical experiences. The hands on testing he showed our team was extremely beneficial. Dave’s presentation piqued a lot of interest and as our team members review the wealth of information on your web site they have come to realize there is a lot they did not know. . . I expect we will have additional questions in the future.
…the floor is awesome! It’s very durable and it’s very convenient that we can lift tiles up to remove debris from underneath, and even replace tiles if they are damaged. So from a functional perspective, this is the best floor for our manufacturing operation.
You would never know it was ESD, WHICH IS AMAZING! Your product rocks and I’m so glad we were able to find an attractive solution that didn’t leave us with some run-of-the-mill ugly disaster in the middle of our workspaces!
