Available in single and dual input versions (up to 8 cylinders) it comes bundles with an advance PC analysis and configuration SW> Built with a rugged aluminum enclosure for rigorous use.
Features: Best-in-class Audio Quality. Improved SNR (signal-to-noise ratio) by 20dB, with much higher audio clarity and 10 times lower noise.
Transflective Display 2.3'' transflective LCD display offers better viewing in daylight and outdoor conditions thus enabling knock detection on the device without a PC being always necessary.
Dual Knock Sensors Inputs Optional dual-knock sensor input with increased dynamic range, suitable for twin bank engines or for enhanced knock detection. Choose whether to split the audio channels per sensor or listen to them combined. 0-5V Analog Load Sensor Input Connect a MAP or TPS sensor and perform 3-dimensional knock data on the device or PC.
Non-volatile Device Logging Memory Capture 3-dimensional knock information and log knock count with knock level per cylinder versus RPM and load.
Dual Audio Output Sockets Benefit from the two audio output sockets by using them either for training your apprentices or for cross-checking the knock signal with colleagues.
Higher-Performance Processor New higher performance main processor improves the calculating speed making the monitor faster and smother in operation/ Dual Power Options!
Now you can power up your knock monitor not only externally but also via its USB port. Detect knock with higher convenience irrespective of where you are.
Isolated USB Port USB port isolation provides electrical protection, more robust device communications and added noise immunity.
