ELECTROSTATIC VOLTMETER ESVM 2000

The electrostatic voltmeter ESVM 2000 is a hand-held non-contacting voltmeter which measures the electrostatic charges

on very small objects. It is an ideal instrument for measurements on semiconductors, printed circuit boards, connector

pins and other areas where a conventional electrostatic fieldmeter cannot be used.

The ESVM 2000 comes with a high resolution sensor which provides accurate results even in very small areas.

• Dimension: 6 x 3 x 13 cm (W x H x D)

• Range: 0 up to ± 2 kV DC

• Accuracy: 5% of full scale

• Recommended Probe-to-Test

surface distance: 15 mm ± 10 mm

• Power supply: battery operated

• Display: LCD-Display ( 3 ½ digits)

• Sensor: probe (10 x 80 mm)

Includes:

ESVM 2000, probe, 9 Volt battery,

conductive carrying case, operating instructions in

German and English and calibration certificate.

CONTACT VOLTMETER ESVM 821HH

The electrostatic contact voltmeter ESVM 821 is a hand-held contact voltmeter which measures

the electrostatic charges on very small objects/surfaces. The ESVM 821 HH measures the

surface potentials on conductive or insulative objects without charge transfer to the probe.

Therefore, measurements can be performed with high accuracy.

• Dimension: 240 mm x 140 mm x 52,5 mm (H x W x D)

• Range: 0 up to ± 2 kV DC or AC (peak)

• Accuracy: < 1% of full scale

• Input resistance: > 1 x 10

ohm

• Input capacitance: < 1 x 10

translated to the electrostatic potential (V) according to the preset

distance. An additional field strength mode is also available.

• Test method: Rotating chopper

• Test range: 0 V – ± 160 kV distance mode

0 – 800 kV/m Field strength mode

• Display: LCD display

• Operation: Battery operated

• Includes: ground cord, German and English operating

instructions and calibration certificate
