Optical probe for reading meters with IEC 62056-21 protocol (formerly IEC 1107) - For M-Bus, DLMS.

Optical probe for reading energy meters equipped with an optical port compliant with IEC 62056-21 (formerly IEC 1107) specifications.

Optical probes allow access to data present in energy meters, gas meters, and water meters that integrate an optical port.
The data here can be read via the M-Bus (Meterbus) or DLMS protocol.

ANDROID application available for download from GOOGLE PLAY STORE, usable with the probes. The application name is ZROBO.

Optical probes are ideal for use with all types of meters. An economical solution for local meter reading. The optical probes have two LEDs on the back that show the operating conditions of the communication. Very easy to use and monitor communication status.
