715
Static Meter
The 715 Static Meter has been developed to enable industrial engineers to investigate static
electricity problems.
Its accuracy, stability and ease of use make it the leading instrument in its class.
Benefits and Advantages
· The 715 measures static electricity on the surface of a material, at a distance of 100mm.
· The meter can show where and how the static is generated, its magnitude and its polarity. This gives the engineer a scientific basis for problem analysis.
· The 715 monitors the effectiveness of the action taken to solve the problem. If the solution involves static control equipment, the 715 shows its most effective position.
· The 715 allows the engineer to set standards to avoid future problems. These can range from an acceptable level of charge in materials, to charge levels in products being produced by the process.
· The 715 has two ranges selected automatically. The high range measures up to 200kV with a resolution of 100V. The low range measures up to 20kV with a resolution of 10V.
· There is a “hold” facility to freeze the reading on the display.
How the 715 works:
Static electricity is a potential problem in many industrial areas. It shows production, reduces
product quality, attracts contaminants and gives shocks to operators.
It is a well-known phenomenon throughout the plastics, packaging, electronics, paper, medical,
pharmaceutical and textile industries – in fact in every area that processes or handles non-conductive
materials.
The 715 enables the engineer to investigate these static electricity problems scientifically. Static is a
coulombic charge – forming current when it moves, but difficult to measure when it is not moving.
The 715 measures the surface voltage using Q=CV : the 100mm reading distance is the constant
capacitance which allows the voltage to vary directly with the charge.
