A broad-range measuring device allows for use of the test instrument in all alternating and 3-phase electrical systems with voltages from 65 to 500 V and frequencies of 16 to 400 Hz.
A broad-range measuring device allows for use of the test instrument in all alternating and 3-phase electrical systems with voltages from 65 to 500 V and frequencies of 16 to 400 Hz.
The Profitest Master Mxtra is a universal electrical installation tester with a broad range of measurements that is ideal for applications with voltages from 65 V to 500 V and frequencies from 15.4 Hz to 420 Hz. A unique advantage of the Profitest Master is its intelligent, ergonomic design. Operation is simple, safe, and data can be conveniently read from the large illuminated display. Device identification data can be quickly entered via a barcode reader, and measurement results are communicated to a PC via a USB interface or Bluetooth.
