Elitech Tlog 100EH Temperature and Humidity Data Logger

The Elitech Tlog 100EH is a reusable probe temperature logger that records temperature and relative humidity from -40 to +85°C through an external probe. Elitech specifies the Tlog 100EH at ±0.3°C (-20 to +40°C), ±0.5°C otherwise accuracy with 0.1°C resolution. On the Tlog 100EH, humidity is measured from 0 to 100 %RH at ±3 %RH (20 to 80 %RH at 25°C), ±5 %RH otherwise. Down to -40°C, the Tlog 100EH covers 2–8°C fridges as well as -20°C freezers. The probe is external temperature-humidity probe on a 107 cm cable.

Memory holds 32,000 readings with an interval settable from 10 s to 24 h, about 333 days of logging at 15-minute steps. Plugging the Tlog 100EH into a PC through its USB connector creates a PDF report automatically. Alarm options on the Tlog 100EH are single and cumulative (up to 3 high and 2 low (temperature)).

Physically, the Tlog 100EH has LCD display and IP65 protection. For calibration, the Tlog 100EH comes with: factory calibration certificate included; ISO 17025 certificate optional. In practice the Elitech Tlog 100EH fits storage areas where humidity affects quality, 2–8°C or frozen.
