OBD PRO NAPRO — RPM and Temperature Reading via OBD

Precise RPM and temperature readings directly from the ECU

The OBD PRO (On-Board Diagnostic Professional RPM Reader) from NAPRO Eletrônica Industrial enables monitoring of engine speed and coolant temperature with high precision, using data available directly from the vehicle ECU via the OBD connector. Unlike external sensors subject to interference, values read via OBD are the same ones used by the engine control system — guaranteeing maximum accuracy.

Communication with the computer can be via USB 2.0 or Class 1 Bluetooth with a range of up to 100 metres, enabling wireless monitoring even when the vehicle is moving or far from the data collection point. Compatible with Otto and Diesel vehicles via the NTCL Net protocol.
