Product Description
The PM21 digital power meter from Esensors provides a highly accurate, cost effective solution for advanced power metering applications. With integrated Wi-Fi/ wired LAN options, PM21 transmits the data through the Ethernet using a built-in TCP/IP Stack. Data is measured continuously and can be viewed using the built-in web interface. Data can also be polled using network monitoring software (eg. Nagios) that may be configured with preset thresholds to setup email alerts.
The low cost PM01 power meter at $240 monitors voltage only.
