Models & Specifications
The HygroLog is available in two configurations:
with or without LC display.

Both models are essentially the same. Because of the display, temperature limits are tighter on the HygroLog D and battery use is twice as high.

On both models, the temperature range of measurements can be widened by using a cable to remote the probe from the data logger.

HygroLog-D

Technical data
Probe standard: ROTRONIC HygroClip-S
other probes on request
Measuring Range 0..100%RH
-40..85°C (-40..185°F)
Humidity Limits 0..100%RH
Temperature Limits HygroLog:     -10..50°C (14..122°F) with alkaline batteries
                    -20..70°C ( -4..158°F) with lithium batteries
HygroLog-D:  -10..50°C (14..122°F) limited by LC display

Both models can measure over a broader temperature range when the probe is remoted with an extension cable (MOK-xx-DAT05).
Example: -40..85°C (-40..185°F) with the HygroClip S probe 
Accuracy at 23°C better than ±1.5%RH and ±0.3°C / 0.5°F
Repeatability < 0.5%RH and 0.1°C / 0.1°F
Recording Modes Start / Stop: programmable up to memory full
Loop: overwrites oldest data
