The LogTag® UHADO-16 Humidity and Temperature Logger measures and stores up to 16,000 sets of high resolution humidity and temperature readings over a measurement range of 0 to 100%RH and -30°C to +70°C (-22°F to +158°F).


The display shows current Temperature & Humidity readings, Alarm status and Recording status.

The UHADO-16 is fitted with three contact pins so it can be used with the LogTag® LTI-USB, LTI-HID and LTI-WiFi Interface Cradles.


When the UHADO-16 is connected to a computer using the integrated USB plug, a detailed PDF report of the recorded humidity and temperature data can be automatically generated without the need for extra accessories and proprietary software.


For more detailed data analysis, the UHADO-16 also creates an encrypted data file compatible with readily available LogTag Analyzer® operating software and LogTag Online®.
