- 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Product withdrawn from the offer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.
- Measurement of external temperature in range -55°C…125°C
