About the Rotronic HygroLog HL-NT
The Rotronic HygroLog HL-NT is a reusable Wi-Fi temperature logger that records temperature and relative humidity from -100 to +200°C. Rotronic specifies the HygroLog HL-NT at ±0.1°C, ±0.8 %RH accuracy. On the HygroLog HL-NT, humidity is measured from 0 to 100 %RH. A lower limit of -100°C puts dry ice and -80°C freezers within reach of the HygroLog HL-NT. The probe is interchangeable HygroClip HC2-xx probes (ordered separately).
The HygroLog HL-NT sends readings over Wi-Fi to HW4, so alerts arrive while the logger is in place.
Physically, the HygroLog HL-NT has Optional LC display and keypad (HL-NT2-D) display. In practice the Rotronic HygroLog HL-NT fits dry ice, -80°C freezers and frozen shipments.
