we are introducing a unique product in the world. After more than 20 years of motorcycle brake dynamo-meter measurements, I had the idea to check the accuracy of the AFR measurement system. Many measurements did not bring the expected results. That is why we have launched the AFR CALIBRATOR GAS SAMPLE product, which can be used to check the authenticity of the exhaust gas measurement. The spray contains a gas mixture suitable for checking 25 probes. Target market: motorcycle/car tuning companies competition teams EFI tuners. Kit contains M18x1,5 adapter for testing O2 sensor.
