Stanley Digital Voltage Tester

Stanley Digital Voltage Tester

is a portable voltage measuring device with 2 methods of measurement, contact and contactless. This means that this device can be used to measure voltage by touching the probe to a voltage source directly (contact) or can also be used to measure the voltage without touching the source of voltage directly (contactless).

To display the reading result, the LCD graph has been provided 0.75 ".The device is compatible for 12 - 220V voltage range either AC or DC.
