Description:

AC single phase with RS485 serial port multi-function monitoring box; can measure voltage, current, power, power, frequency, power factor, maximum 10A! It can display six measurement parameters on the computer when communicate through the software; it can also communicate with the buyer's own micro controller (the buyer should program by yourself)!

The high accuracy, better compatibility will make it use widely.
