ALTA Wireless Voltage Detection - 200 VDC - AA Battery Powered, 900MHZ

The Monnit Voltage Detector - 200 VDC detects the presence or absence of electricity. It is intended for use on battery or other DC sources, up to 200 Volts. Not intended for use with AC Voltages. It is perfect for batteries, adapters, solar equipment, vehicles or machinery, and any other electrical appliance monitoring. The sensor triggers on voltage presence to voltage Absence and vice versa. The data is displayed as "Voltage Detected" or "No Voltage".
