TFA Dostmann digital thermo-hygrometer Comfort Control 30.5011 (Misc.)
Buy at Amazon.com

Customer Review

the deviation of the hygrometer was 1.5 points.

The deviation of the temp was 0.1 points.

Measurement setup Horizontal, devices placed in a circle display inward, so that the air from the outside could emphasize through device.

If one now considers that the same devices at 6 and these are not calibrated, are the very good values.

Would not hesitate to re-buy these devices.
