Radio Ampstik

The Radio Ampstik by Sensorlink is radio linked multiple reading ammeter

The Radio Ampstik is a radio linked high voltage ammeter and uses the same current sensor technology as the original Ampstik. The key feature of this unit is the ability to display the current reading up to 50 feet (15 m) from the sensor on the remote receiver.The user has the option to hold the receiver in their hands, mount it to a hot stick or hang it on the bucket.

The current sensor doesn't use magnetic materials and has no moving parts. The 2.5 inch (6,35 cm) opening of the sensor is electronically closed and external currents are also electronically rejected. Is durable and able to accurately measure from 1 to 5000 amps.


  • Heads-up display for instant confirmation of the reading.
  • Records up to four readings.
  • Remote read out up to 50 feet (15 m) away.
  • Slips on and off the conductor with 1% accuracy.
  • Open CT that rejects stray magnetic fields.


  • Verify current before breaking load.
  • Spot verify current when investigating power diversion.
  • Check for load balance.
  • Conduct load studies.
