HumidiProbe is the straightforward and practical way to measure and record humidity and temperature using your PC.


  • Records temperature and relative humidity
  • Measures 0 to 100% RH (non-condensing)
  • Measures 0 to 70 °C
  • Small form factor design
  • Connects to a PC or laptop via a USB port
  • No power supply required

The HumidiProbe is a self-contained humidity and temperature measuring data logger. Simply position the HumidiProbe near the source you want to measure, plug the cable into the USB port on your PC, and you're ready to measure humidity and temperature.

Monitoring temperature and humidity is very important: temperature and humidity play an important part in health, comfort and productivity. Extreme temperatures can also cause electronic equipment to age faster and mechanical equipment to breakdown. If humidity is too high it can lead to corrosion of equipment, mould growth — even printers jamming; if the humidity is too low it can lead to problems with static electricity and dehydration problems with everything from wine making to wood storage.

Versatile and expandable

HumidiProbe

The HumidiProbe's compact, all-in-one design allows it to be used in various locations and in a wide range of applications. Up to 4 HumidiProbes can be connected to one PC allowing you to accurately monitor the temperature and humidity in multiple locations at once, and at a low cost.

Easy to use software

The easy to use PicoLog data acquisition software is supplied with the HumidiProbe — this powerful, yet flexible, data acquisition software allows you to collect, manipulate, analyse, and display and export data. Software alarms can be configured for both temperature and humidity so as to provide a warning when measurements go out of a specified range. Updates to PicoLog can be downloaded for free from the Pico website.

An accurate and cost effective solution

If you need to measure, and record, temperature and humidity the HumidiProbe provides you with a complete solution that is compact, simple to use, accurate and cost effective.
