Analog Static Charge Meter

Analog Meter instantly measures static charges. Achieve higher resolution when measuring below 3000 volts by setting the range selector to LOW setting; measure up to 30,000 volts in the HIGH range simply by multiplying the reading by ten. The "quick zero" function re-zeros the meter for repetitive measurements. Digital Meter with Output measures electrostatic fields by increasing the meter to charged surface distance. Meter features a 3-½-digit, 0.4"H LCD. HOLD button freezes current reading. Easily zero the meter with the turn of a knob, there is no need to re-zero between measurements. The output lets you permanently record your results. Order charge plate detector separately to verify proper operation of air ionizers and increase meter sensitivity by a factor of ten.
