Photocells - Polifemo Radio

 Fotocellule - Polifemo Radio - Professional Timing | Microgate

The radio system embedded in the Polifemo photocell allows easy and rapid positioning of the photocells wherever you want along the course. The timekeeper can then receive the total time via radio and take up to 6 intermediate times, all of them identified.

  • EncRadio SF impulse transmission system embedded in the photocell
  • Selection of 16 transmission channels
  • Radio transmission range of about 2 km.
  • Selection of impulse type (start, stop, up to 6 laps, each one individually identified)
  • Reflection functioning with a range of over 35 metres;
  • Low battery indicator;
  • Embedded ‘smart’ recharge circuit;
  • Possibility of substituting the rechargeable batteries with two AA batteries (over 15 hours of battery life)
