Ultra Stable Surface DC Volt Meter

Manufactured in the USA by AlphaLab, Inc.

SKU: USSVM $570.00

This is a chopper-stabilized (rotating) sensor meter with a remote sensor head at the end of a 100 cm long flexible cable. It measures down to 1/10 volt on a surface, and up to 20 000 volts (20 kV). Readings are normally done with the sensor 1" (2.5 cm) from the surface being tested. This meter is unaffected by an ionizing environment (an environment with electric sparks nearby). It does not require manual resetting; the "Zero Fine Adjust" knob (on the right-side surface) only needs to be set once to offset any existing voltage on a surface, if desired, up to +/- 15 volts. At 1/10 volt resolution, it is the most sensitive electrostatic meter available.
