The RPM Counter 165 is a Tecnomotor device designed to measure engine RPM and temperature directly via the OBD port, without the need to connect sensors in the engine compartment. Completely wireless, it transmits data to a PC or diagnostic tools via a Bluetooth connection, simplifying testing and maintenance procedures.
Equipped with a large transflective graphic LCD display, it ensures clear and immediate readings even in direct sunlight. The rechargeable lithium battery, built-in shock protection, and compatibility with major OBD protocols make it a practical and reliable solution for auto repair shops and inspection centres.
The product line also includes the RPM Counter 165 version with a battery detection adapter, which allows engine RPM to be measured either via the EOBD port or directly from the vehicle’s battery. Dedicated accessories are also available, such as a vibration sensor, an oil temperature probe, and a kit for measuring RPM from the battery.
