Glass Aquarium Thermometer AQUA DELLA model 227/103852 — thick glass, stick-on or submersible use

Glass aquarium thermometer AQUA DELLA model 227/103852 is a compact tube-style temperature sensor made from thick glass for aquarium use. The thermometer indicates water temperature with a clear scale and is designed for either stick-on attachment to the inside tank wall or for fully submersible placement. It is suitable for both freshwater and marine aquaria where reliable temperature monitoring is required to maintain stable conditions for fish, plants and invertebrates.

Advantages

The thick glass construction provides mechanical strength and good thermal contact with the water column while remaining chemically inert and corrosion-resistant. The compact tube design allows unobtrusive placement inside the aquarium and the dual mounting options — adhesive attachment or free submersion — give flexibility depending on tank layout and monitoring preferences. The visible temperature scale enables quick visual checks without electronic components or power requirements.

Suitable for

• Freshwater aquariums where regular temperature checks are needed
• Marine and reef tanks for monitoring stable temperature conditions
• Breeding setups and planted tanks that require consistent thermal control
• Temporary measurements during water changes or equipment checks

Key specifications

• Material: thick glass tube designed for aquarium environment
• Display type: analog temperature scale visible on the tube
• Mounting options: adhesive stick-on to the inner tank wall or fully submersible placement
• Use environment: suitable for freshwater and saltwater aquaria
• Dimensions: compact tube form factor for minimal visual impact

How to use

For adhesive mounting, clean and dry the inside surface of the aquarium glass, remove the protective film from the adhesive pad (if supplied) and press the thermometer against the glass at the desired depth so the sensor is in contact with aquarium water. For submersible use, place the thermometer fully underwater positioned away from direct heater output or strong water flow to obtain a representative reading. Allow several minutes for the thermometer to equilibrate with tank temperature before reading the scale. Avoid placing the glass thermometer where it may be contacted frequently by fish or maintenance tools.

Usage recommendations

Check the thermometer regularly as part of routine aquarium maintenance and compare readings with other temperature monitoring devices when adjusting heaters or after major water changes. Inspect the glass for chips or cracks; replace the thermometer if any damage is found to prevent breakage in the aquarium. When attaching with adhesive, use a pad rated for aquatic environments and ensure secure placement to avoid accidental detachment.
