LogTag UHADO-16

Humidity & temperature multi-use data logger

Humidity & temperature multi-use data logger


  • Record and display Temperature & Humidity readings simultaneously
  • Up to 16,000 sets of recordings - enough for the longest trip
  • Automatic generation of a PDF report without special software
  • Supports fast download using standard LogTag® Interface cradles, including those with WLAN connection
  • User configuration for alarm settings, logging interval, trip duration etc.
  • Audible alarm & red LED signals a temperature alarm.


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.

Product Model UHADO-16
Temperature Sensor Measurement range -30 °C to +70 °C (-22 °F to +158 °F)
Recorder operating temperature range -30 °C to +70 °C (-22 °F to +15 8°F)
Storage Temperature Range +10 °C to +50 °C (+50 °F to +122 °F)*
Rated Temperature reading accuracy Better than ±0.45 °C (±0.8 °F) for +0 °C to +50 °C (+32 °F to +122 °F), typically ±0.3 °C (0.6 °F). Better than ±0.8 °C (±1.4 °F) for +50 °C to +70 °C (+122 °F to +158 °F), typically ±0.5 °C (0.9 °F). Better than ±0.95 °C (±1.7 °F) for -40 °C to +0 °C (-40 °F to +32 °F), typically ±0.6 °C (1.1 °F). Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration

Humidity Operating Range 0% RH to 100% RH (non-condensing), with limitations
Storage Humidity Range 20% RH to 60% RH*
Humidity Resolution Better than 0.1% RH
*Optimal Storage Condition For optimal Humidity logger storage, store units in original packaging in an air conditioned area. Storage temperature shall be in the range of 10°C to 50°C and humidity at 20 to 60%RH. Ensure good ventilation (fresh air supply) in storage area to avoid high concentrations of volatile chemicals. Do not store units in the same room as solvents or any other strong smelling products.
Rated Humidity Reading Accuracy Better than ±3%RH for 20%RH to 80%RH, typically ±2%RH. Better than ±5%RH for 0%RH to 20%RH, typically ±4%RH. Better than ±5%RH for 80%RH to 100%RH, typically ±4%RH. Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration.

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.
