Digital thermo-hygrometer tfa dostmann 30.5027.02 — temperature and humidity measurement

Compact digital thermo-hygrometer tfa dostmann 30.5027.02 measures ambient temperature and relative humidity and displays current values on a clear screen. The device is designed for indoor use in homes, offices and storage spaces to help monitor climate conditions. By providing continuous readings of temperature and humidity, it enables timely ventilation, heating adjustments or dehumidification to protect comfort and stored items.

Advantages

The thermo-hygrometer offers a compact design with easy-to-read display and straightforward operation. It provides accurate temperature and relative humidity readings suitable for everyday indoor monitoring and requires minimal setup or maintenance. Its small footprint allows placement on desks, shelves or mounting on walls to fit different monitoring needs.

Suitable for

• Monitoring room climate in living rooms, bedrooms and nurseries
• Office environmental monitoring at workstations and meeting rooms
• Storage and archive monitoring to protect sensitive items and documents
• Greenhouses and indoor plant areas where humidity control is important
• Cellars and laundry rooms prone to excess humidity

Key specifications

• Measured parameters: ambient temperature and relative humidity
• Display: digital readout for temperature and humidity
• Intended use: indoor monitoring
• Power supply: battery-powered (user-replaceable batteries)
• Mounting options: free-standing or wall-mounted
• Compact physical dimensions suitable for desk or wall placement

How to use

Place the thermo-hygrometer on a stable indoor surface or mount it on a wall at approximately eye level away from direct sunlight, heaters or drafts for representative readings. Insert the required batteries, allow the sensor to stabilise for several minutes and read the current temperature and relative humidity on the display. For long-term monitoring, check the device periodically and replace batteries when the display dims or readings become inconsistent.

Usage recommendations

Position the device in the area you want to monitor rather than near windows, radiators or ventilation outlets to avoid distorted measurements. For storage rooms and archives, aim to keep relative humidity and temperature within ranges recommended for the stored materials and use the thermo-hygrometer to verify the climate before taking corrective actions such as ventilating, heating or using dehumidifiers.
