The LittleDoctor is the brainchild of an electrical engineer and physics teacher.  In both his work and his teaching, he noticed that there is a great need for a versatile data logger that can give good, reliable performance without the astronomical price of the existing professional models.  To solve this problem, he invented the LittleDoctor.

The LittleDoctor comes packed with features including:

  • USB Connectivity
  • Screw Terminal Connections
  • 10-bit Voltage Resolution
  • 1% Basic Voltage Accuracy
  • Up to 4750 Samples/Second
  • 8 Analogue Voltage Inputs
  • x10 Amplifier on 2 Inputs
  • 2 Microphone Input Jacks
  • Internal Temperature Monitor
  • Internal Light Monitor
  • 3 Digital on/off Inputs
  • Frequency Counter Digital Input
  • Time Interval Digital Input
  • Analogue Output (e.g. Sine Wave)
  • Variable Frequency Digital Output
  • On-off Power Output with LED
  • Graphs any Inputs Simultaneously
  • Print Graphs or Copy to Clipboard
