MIGCON ML-4W WiFi data logger with external probes

WIFI Data Logger (External Sensor)

Model ML-4W


  • Five sensor types on one logger — RTD, type K or T thermocouple, thermistor, 4-20mA or 0-1V, predefined at order so it arrives ready to use.
  • −200 to 800°C span — cryogenic storage through to furnace and autoclave work, with precision set by the sensor you choose.
  • Multi-channel logging to your dashboard — 40K readings on one channel or 20K per channel, streamed over WiFi to cloud or local server software.
  • Battery backup behind the 5VDC adapter — a 3.6V lithium half-AA keeps recording through a power cut, so the compliance record has no gaps.
