10-bit Data Logger for Innovation and Accuracy  

Two data logger models are available:

  • Internal Temperature sensor plus one external sensor input
  • Humidity and Temperature sensors plus one external sensor input

The 10-bit MicroLogPRO carries all all the benefits of the 8-bit MicroLog plus some additional innovative new features.

  • Higher sampling resolution for more
    accurate readings
  • Increased memory - 52,000 samples
  • Enhanced 4 digit LCD display

MicroLogPRO 10-bit offers a Temperature data logger and a combined Humidity and Temperature humidity data logger together with a full range of external sensors.

The MicroLogPRO is fully featured, enabling its use in a wide range of applications including pharmaceutical; food production and storage; transportation; museums, clean rooms and HVAC, to name a few.
