GF12R Smart Infrared Photoelectric scanning head for testing of electronic meters
The photoelectric scanning head Type GF12R is especially designed to detect pulses from electronic meters and Mechanical energy meter. A permanent ring-magnet is built into the scanning head, thus enabling the GF12R scanning head to be magnetically attached to meters with built-in
metal ring or magnet around the light emitting diode. Thanks to this magnetic holding device, the scanning head can be used for both measurements on meter test consoles or in the field.
