Thermometer and Humidity Gauge TechnoLine WA3055 — Classic Analog Indoor Measurement

The TechnoLine WA3055 is a classic analog indoor thermometer combined with a humidity gauge that displays ambient temperature and relative humidity on a single dial. Designed for simple, battery-free operation, this mechanical instrument gives immediate readings for monitoring home, office or storage conditions. The clear scale and compact housing make it easy to mount or place on a flat surface for continuous passive climate observation.

Advantages

The WA3055 combines two measurements—temperature and relative humidity—on one analog display, eliminating the need for power or electronic maintenance. Its mechanical movement provides reliable, low-maintenance readings and a straightforward visual reference for assessing indoor climate. The device’s compact design allows placement on desks, shelves or walls without requiring additional installation tools.

Suitable for

• Monitoring room climate in living rooms, bedrooms and offices
• Protecting stored items in closets, cabinets and basements
• Checking conditions in hobby rooms, workshops and greenhouses (indoor, non-extreme environments)

Key specifications

• Measurement types: ambient temperature and relative humidity
• Display: analog dial with separate scales for temperature and humidity
• Power: mechanical operation, no batteries required
• Mounting options: free-standing or wall-mounted
• Housing: compact, lightweight casing suitable for indoor use

How to use

Place or mount the WA3055 at the height and location representative of the space you want to monitor, away from direct heat sources, open windows or humidifiers to ensure accurate ambient readings. Allow the instrument to stabilize for several minutes after placement before reading the dial. Read the temperature and relative humidity directly from their respective scales; periodic visual checks are sufficient for most indoor monitoring needs.

Usage recommendations

For consistent readings, avoid placing the device near radiators, direct sunlight or ventilation outlets. If used for storage monitoring, position the gauge inside the storage area rather than outside to reflect internal conditions. Clean the casing with a soft, dry cloth and avoid exposure to excessive moisture or corrosive substances.
