LogTag UHADO-16 Temperature and Humidity Data Logger

The LogTag UHADO-16 is a reusable temperature and humidity logger that records temperature and relative humidity from -30 to +70°C. LogTag specifies the UHADO-16 at ±0.45°C (0 to +50°C), ±0.8°C (+50 to +70°C), ±0.95°C (-30 to 0°C) accuracy with 0.1°C resolution. On the UHADO-16, humidity is measured from 0 to 100 %RH at ±3 %RH (20 to 80 %RH), ±5 %RH (0 to 20 and 80 to 100 %RH). Down to -30°C, the UHADO-16 covers 2–8°C fridges as well as -20°C freezers.

Memory holds 16,128 readings with an interval settable from 30 s to several hours, about 168 days of logging at 15-minute steps. LogTag lists the maximum runtime of the UHADO-16 as 112 days at 10 min, 168 days at 15 min logging. Recording on the UHADO-16 starts by button and scheduled. Plugging the UHADO-16 into a PC through its USB connector creates a PDF report automatically, with CSV and LTD export as well. Alarm options on the UHADO-16 are high/low (4 temperature, 2 humidity).

Physically, the UHADO-16 has LCD display, IP61 protection and a replaceable battery. Unstarted UHADO-16 units have a shelf life of 1 year storage. In practice the LogTag UHADO-16 fits storage areas where humidity affects quality, 2–8°C or frozen.
