Electrostatic Field Meter

Basically, there are various types of field meters as indicative and quantitative. The indicative meter is generally simpler in construction and indicates whether the electrostatic field is large or small with the help of some kind of LED display, which in itself is a challenge for interpretation. In practice, one can only determine if the electrostatic field is large or small, which makes it difficult to compare different measurements with each other. The advantage of quantitative field meter is the ability to categorize, compare, identify, and store different measurements for various process and product conditions, which in turn facilitates documentation of troubleshooting, process optimization and so on for future use.

Some field meters cannot be used near ionizing equipment, due to discharging of the field meter which results in incorrect readings.

Thus, for measuring static electricity it is important that adequate measurement equipment is used to ensure if the problem is related to static electricity or not, e.g. for continuous monitoring of critical processes, troubleshooting of a production line, etc.
