TP-15 Dual-frequency optical scanning probe for accuracy test

TP-15 is two-frequency switchable optical scanning probe for meter accuracy testing.

  • Frequencies of optical pulses and electric pulses keeps the same, this mode is for normal meter constant.
  • The optical pulse is divided by 4 to electric pulse, this mode is designed for very high meter constant.


Light sense: TP-15 optical scanning probe can sense both light and IR(Infrared) light pulses emitted by LED, and then convert them to electric pulses.
Switching: The optical pulse can be switched by a press button, one LED indicating the frequency: green means1:1 and red 4:1.
Power supply: DC 5V±10%
Cable: Straight-line cable, 55cm in normal
Fastening: Magnetic adhesion
Connector: Optional item from Table of Connectors for Optical Scanning Probes.
Probe Fixture: TP-GS fixture can be used for probe fastening onto any type of meters.
