  • Description

    Product withdrawn from the offer

    • power to the analyzer is supplied from tested mains (internal power supply) and is used in all types of networks from 64 V to 760 V,
    • with particular emphasis on measurements at low voltage poles, due to the ease of connection.
    • has an independent power supply socket, especially suited for voltage measurements for transformers and DC circuits.
    • remote control and data transfer through a built-in GSM modem (GPRS),
    • anti-theft feature - SMS notification in the event of position change - built-in GPS receiver,
    • real-time clock synchronized to GPS protocol.
