Ultra Stable Surface DC Volt Meter

USSVM2 - Alpha Lab, Inc. (Trifield)

The meter measures the magnitude and polarity of static charge on objects or surfaces. The sensor is calibrated for measuring a surface at 1" from the end of the sensor. On metallic or conductive surfaces, the meter measures the voltage on the surface. (As with any electrostatic voltmeter, the displayed reading depends somewhat on the size of the object being measured and the distance between the object and the sensor.) On insulating surfaces, "voltage" is not a well-defined number. In this case, the meter reads a number proportional to the static charge present.
