Why Influx Technology
Built to work with what you already have
Learning hub
Start with eight thermocouple channels. Stack a second module for sixteen. Add analog voltage, vibration or wide-range voltage measurement and they stack too, sharing a single CAN bus. Channel count is limited by CAN bus bandwidth, not by the hardware. Scaling up doesn't mean replacing what you already have.
Stackable instrumentation
InstrumentationSensor measurements are synchronised with vehicle network data on the CAN bus. Compare a thermocouple reading, a vibration spike and an ECU fault code against the exact moment they happened. No stitching separate files. No offset guessing. Just aligned data from the moment it hits the bus.
One recording, one timebase
