Product information

Description

TFA 30.5055.02 is a compact indoor electronic hygrometer and psychrometer with a rectangular digital display designed to monitor relative humidity and temperature. Housed in a white casing measuring 55 × 40 × 15 mm and powered by a single 1.5 V battery, this device records current values and stores maximum and minimum readings for later review. It can be placed on a flat surface using the fold-out stand or attached to metal surfaces with two small magnets on the back. The climate comfort display provides an immediate visual indication of conditions using a smiling, neutral, or sad face. The device offers four selectable application modes to match common monitoring needs: room climate, musical instruments, tortoise terrariums and humidor storage.

Advantages

The hygrometer provides clear digital readout of temperature and relative humidity in a small, easy-to-position housing suitable for a variety of indoor locations. Stored maximum and minimum values are accessible with a button press, enabling monitoring of fluctuations over time. The selectable comfort-mode settings and intuitive smiley climate indicator make it simple to evaluate whether conditions fall into recommended ranges for general indoor comfort, wooden musical instruments, tortoise enclosures or cigar humidors. Battery operation and built-in magnets plus a fold-out stand offer flexible placement options without the need for permanent installation.

Suitable for

Monitoring room climate in homes and offices
Protecting and storing wooden musical instruments
Maintaining appropriate conditions in tortoise terrariums
Controlling humidity and temperature inside humidors for cigars
Monitoring small storage areas, greenhouses or cabinets

Key specifications

Measured values: relative humidity and temperature
Display: rectangular digital screen with comfort indicator
Dimensions: 55 × 40 × 15 mm
Power supply: 1.5 V battery (single cell)
Modes: selectable application modes for room climate, musical instruments, tortoise and humidor
Memory: records and displays maximum and minimum values
Mounting options: rear magnets for metal surfaces and fold-out stand for tabletop use

How to use

Insert the 1.5 V battery into the battery compartment and place the device in the desired location away from direct heat sources and strong sunlight for representative readings. Choose the appropriate application mode (room climate, musical instruments, tortoise or humidor) to align the comfort indicator with the relevant recommended ranges. Use the max/min button to view stored extreme values and monitor changes over time. Attach the hygrometer to a metal surface using the magnets or stand it upright on a flat surface with the fold-out stand. Check readings regularly and replace the battery when the display becomes dim or unresponsive.

Usage recommendations

For reliable monitoring, position the device where air circulates freely and avoid placing it directly next to radiators, ventilation outlets or humidifiers. For instruments and humidors, aim to keep conditions as stable as possible; review stored maximum and minimum values frequently to detect and correct strong fluctuations. When using the tortoise mode or storing sensitive items, verify species- or product-specific humidity and temperature requirements and adjust environmental controls accordingly.
