The Static Meter electrofield meter is a small hand-held field strength meter with digital display for measuring electrostatic charges in Volt. It perfectly combines easy operation with accurate measuring technique.
The Static Meter measures charges according to the field influence principle C: The influenced charges, caused by the electrical field, generate an alternating current proportional to the electrical field strength. The selective amplifier converts this value into the corresponding field strength or electrical potential - without withdrawing energy from the electric field over the averaged time.
Special Features and Advantages:
- Variable measuring distance :In order to obtain optimum results, the distance between test object and sensor head - depending on the degree of charge and the condition of the object's surface - can be selected incrementally
- Hold function : The device is equipped with a Hold function to keep the measured value stored on the display.
- Display in Volt :The integrated micro-computer automatically converts the measured field strength into the equivalent charge in Volt.
Mode of Operation:
Field pattern of a uniformly charged film A and of a uniformly charged film above the earthed/grounded metal plate B: The electric field of the electrostatic charge is converted into a measuring alternating current through the cyclical covering of the sensor plates. The display shows a tension proportional to the intensity and polarity of the field to be measured.
Field strength meters that work according to this principle have a high measuring sensitivity and allow very accurate measuring.
Two 26 mm long spaces are supplied together with the device. These ensure that the distance of measurement is always correct (= 2 cm).
The LG is an indispensable production aid for film processing, electronic manufacture, and precision mechanics. This device has also proven to be very reliable and efficient for the manufacture of measuring devices and control gears, for pcb assembly as well as for screen and pad printing and other printing procedures.
