Thermometer Hagen Minerva self-adhesive model 010628 for aquarium/terrarium

The Hagen Minerva self-adhesive thermometer model 010628 is a compact dial thermometer designed for aquarium and terrarium use. The instrument adheres to the outside of the glass and displays the surface temperature of the habitat, allowing visible, continuous monitoring without insertion into water or substrate. Its small size and adhesive backing make it suitable for routine checks and general temperature monitoring of fish tanks, reptile enclosures and other small vivaria.

Advantages

The self-adhesive mounting eliminates the need for probes or immersion, reducing stress to animals and simplifying installation. The analogue dial provides an immediate, easy-to-read temperature indication. Because it attaches to the outside glass, it avoids direct contact with water or humidity-sensitive electronics and is easy to reposition or replace as needed.

Suitable for

• Aquarium temperature checks for freshwater and community tanks
• Terrarium temperature monitoring for reptiles and amphibians
• Portable or temporary setups where non-invasive measurement is preferred
• General habitat maintenance and routine visual inspections

Key specifications

• Type: Self-adhesive analogue dial thermometer
• Mounting: Adhesive backing for external glass attachment
• Measurement method: Surface temperature reading through glass
• Display: Analog dial with temperature scale
• Size: Compact, designed for small to medium-sized enclosures

How to use

Clean the outside surface of the aquarium or terrarium glass where the thermometer will be placed, removing dust, algae or condensation. Peel off the protective film from the adhesive backing and press the thermometer firmly against the glass from the outside. Allow a short settling time for the reading to stabilise; avoid placing the unit near direct heat sources, filters or lighting that could affect the surface temperature. Read the temperature from the analogue dial through the glass.

Usage recommendations

Check readings regularly and compare with a secondary thermometer if precise control is required. For aquatic setups where water temperature control is critical, use this external adhesive thermometer as a quick visual check and complement it with an immersion probe or digital controller when precise monitoring is needed.
