High Frequency Electric Pokers The name is slightly misleading as the frequency of vibration is a rather standard 200hz (12000 vibrations per minute).  The “high frequency” part of the name comes from the electric supply given by the convertor.  Regular mains supply of 50/60 hz is converted to 200hz to power an in-head motor. The supply is also stepped down to a safer 42v.  The mains power delivers enough motive force to maintain good amplitudes whilst the motor and vibrator remain synchronised with the 200hz supply. As electric supplies are becoming more common on construction site this type of poker is gaining popularity. They deliver good vibration from a plug in and switch on unit. This on site simplicity and clean running has it’s place on advanced construction sites. Please see the downloads section for our guide on how to use concrete poker vibrators.
