The 3M™ 718 Static Sensor is a portable, handheld instrument designed for measuring voltages associated with electrostatic charge. Its intended use is for measuring the amount of voltage, in a range from 0-20 kilovolts, associated with an electrostatic charge buildup on a surface. Any deviation from this intended use could impair the instrument’s effectiveness and possibly lead to an unsafe operating condition. The 3M™ 718A Air Ionizer Test Kit is a set of accessories for use in conjunction with the 3M 718 Static Sensor. Their intended use is for verifying the operation of air ionizers by measuring the neutralization time for a static charge placed on a stationary metal plate. Any deviation from this intended use could impair the instrument’s effectiveness and possibly lead to an unsafe operating condition.
