Product information

Description

The TFA-Dostmann 30.5055.02 indoor temperature & humidity sensor is a compact, freestanding device for monitoring room climate. It shows current temperature and relative humidity, stores maximum and minimum values for later review, and offers a climate comfort display that classifies conditions with a smiling, neutral or sad face. The unit can be placed on a flat surface using its fold-out stand or attached to metal surfaces with two small rear magnets. Four selectable application modes—room climate, musical instruments, tortoise and humidor—allow quick selection of the appropriate reference range for each use case.

Advantages

The sensor is small and battery-powered (1.5 V), making it easy to position anywhere indoors. It records and displays maximum and minimum readings at the push of a button and provides a clear visual comfort indicator for immediate assessment. The two magnets and fold-out stand offer flexible mounting options, while the four predefined application modes simplify monitoring for specific needs such as instruments, pets or cigar storage.

Suitable for

Monitoring general indoor climate in living rooms, bedrooms and offices
Protecting wooden musical instruments (pianos, violins, guitars) from harmful humidity fluctuations
Maintaining appropriate terrarium conditions for tortoises (activity phase)
Controlling humidity and temperature in humidors for cigar storage

Key specifications

Model: TFA-Dostmann 30.5055.02
Power supply: 1.5 V battery
Form factor: freestanding with fold-out stand; two rear magnets for metal surfaces
Measurements displayed: temperature (°C) and relative humidity (%)
Functions: current reading, max/min memory and recall, climate comfort indicator, four application modes
Dimensions (approx.): 55 mm × 15 mm × 40 mm

How to use

Insert a 1.5 V battery, place the device on a flat surface or attach it to a metal surface using the rear magnets, and select the desired application mode (room climate, musical instruments, tortoise or humidor). Read the current temperature and relative humidity directly from the display. Press the button to view stored maximum and minimum values. Use the climate comfort icon to quickly assess whether conditions are within the recommended range for the selected mode.

Usage recommendations

For room climate monitoring, aim for 19–25 °C and 40–60% relative humidity. For many wooden musical instruments, 18–24 °C and 45–55% RH are advisable and conditions should remain as stable as possible. For European tortoises during their activity phase, 25–32 °C and 45–65% RH are typical; check species-specific needs. For cigar humidors, 18–22 °C and 65–75% RH help preserve aroma and storage life.
