## Summary description

## Long description

AQUA DELLA LCD Aquarium Thermometer EB-3906 — Stick-on Digital Temperature Display is an adhesive-backed LCD thermometer designed for continuous external monitoring of aquarium water temperature. The slim, battery-powered unit attaches to the outside of the tank glass and shows temperature in degrees Celsius on a clear digital screen. Designed for both freshwater and marine tanks, it provides fast response readings that help maintain stable conditions for fish, plants and invertebrates without exposing electronics to moisture.
Advantages
The stick-on design allows placement anywhere on the external glass for unobtrusive monitoring. The LCD display provides clear numerical readings in Celsius, making it easy to check temperature at a glance. Because the sensor is mounted outside the tank, the thermometer remains dry and reduces the risk of corrosion or electrical contact with water. The compact profile and adhesive backing enable quick installation and repositioning as needed.
Suitable for
 Home freshwater aquariums
 Saltwater and marine tanks
 Breeding or planted tanks where stable temperature monitoring is required
 Temporary setups, quarantine tanks, or transport containers with glass walls
When it may not be suitable
This external stick-on thermometer measures glass surface temperature and infers water temperature; readings may differ slightly from in-water probes, especially if the tank has strong heating or cooling gradients. It is not designed for direct immersion and should not be used where a waterproof submerged sensor is required for precise control of heaters or chillers. Adhesive performance can degrade on very textured, curved or dirty glass surfaces.
Key specifications
 Display type: LCD digital readout
 Temperature unit: Celsius
 Mounting: adhesive-backed stick-on sensor for external glass mounting
 Power: battery-powered (internal cell)
 Suitable tank types: freshwater and marine aquariums
 Response: quick display update for ongoing monitoring
 Construction: compact, low-profile housing to minimize visual impact
How to use
Clean and dry the outside of the aquarium glass at the desired location to ensure good adhesive contact. Peel the protective film from the adhesive backing and press the thermometer firmly against the glass, avoiding air gaps. Allow a short settling time for the sensor to match the tank temperature and then read the value on the LCD display. Reposition or replace the unit as needed by gently removing it and applying to a new, cleaned spot. Replace the internal battery when the display becomes dim or unresponsive.
What to consider before purchase
 Intended use: external monitoring only, not for immersion
 Surface condition: requires clean, flat glass for best adhesion
 Accuracy needs: in-water probes may be required for precision control
 Battery maintenance: check and replace internal battery as needed
Usage recommendations
Place the thermometer at mid-height on the tank glass away from direct heater output or heavy filtration flow to obtain representative readings. For critical temperature control, use this stick-on display together with an in-water temperature probe for calibration and cross-checking.
