LogTag® UHADO-16 Humidity & temperature made easy

The LogTag® UHADO-16 Temperature & Humidity logger measures and stores up to 16,000 sets of high resolution humidity and temperature readings over a measurement range of 0~100 % RH and -30 °C to +70 °C.

Product Summary

The display shows current Temperature & Humidity readings, Alarm status and Recording status. By pushing the “Review” button, the user can check minimum and maximum Temperature & Humidity readings for the trip, and the duration of any Temperature & Humidity recordings in the Alarm range.

The UHADO-16 can be connected directly to a computer for configuration and data download using a standard Micro-USB to USB cable. The user has the option of automatically generating a PDF report on download. In addition, the UHADO-16 is fitted with three contact pins, meaning that it can be used with the LogTag® LTI-HID and LTI-WiFi Interface Cradles. Data can be processed using readily available LogTag® Analyzer and LogTag® Online cloud.



The multi-use data logger UHADO-16 is deployed whenever relative humidity (%RH) monitoring plays an important role in addition to temperature measurement.
This USB logger can be used in a variety of different applications, for example in pharma and food industries, but also in transport and warehousing or for monitoring museums and other indoor facilities. The PDF logger is not only compatible with any USB interface, but can also be connected directly to a PC via a USB lead.
