Diris A30 - A41

DIRIS A-30/A-41

Multifunction performance metering & monitoring device - PMD Energy monitoring

The DIRIS A-30 and A-41 are performance metering & monitoring devices that provide the user with all of the measurements needed to complete energy efficiency projects and to assure the monitoring of electrical distribution. All of the this information can be used and analysed remotely using energy efficiency software packages.

Advantages

User-friendly operation

With its large backlit multiple-display screen with 6 hot keys, the DIRIS A-30 is easy to use.

Detects wiring errors

The DIRIS A-30 is provided with a correction function for TC wiring errors.
