Sera suction cups for precision thermometer, pack of 2 — compatibility accessory

Replacement suction cups from sera for precision thermometers, supplied as a pack of two. These small mounting elements are intended to attach a thermometer securely to aquarium glass or other smooth, non-porous surfaces, ensuring stable positioning for continuous temperature monitoring. The design matches common mounting points on compatible sera thermometer models and similar devices, providing a simple spare or replacement solution when original cups are lost or worn.

Advantages

These suction cups are sized and shaped for reliable adhesion to flat, smooth surfaces and help keep a thermometer in the optimal viewing position without adhesive or permanent mounting. Supplied as a pair, they allow replacement of both cups on a single thermometer or provide a spare for future use. The material resists typical aquarium conditions and supports repeated removal and reattachment without losing functionality.

Suitable for

• Attaching a precision aquarium thermometer to glass walls
• Replacing worn or lost suction mounts on compatible thermometer models
• Temporary mounting of small temperature sensors on smooth surfaces

Key specifications

• Pack quantity: 2 suction cups
• Material: flexible, water-resistant elastomer
• Mounting type: suction cup for flat, smooth surfaces
• Intended use: external mounting for small precision thermometers and sensors
• Compatibility: designed to fit sera thermometers and similarly sized devices

How to use

Before attaching, clean the glass or other smooth surface with a lint-free cloth to remove dust and residues. Moisten the suction face slightly if recommended by the thermometer manufacturer, press the cup firmly against the surface while holding the thermometer in the desired position, and ensure the cup’s rim makes full contact to create a vacuum seal. To remove, gently lift an edge of the cup and peel it away from the surface. Replace both cups if one shows signs of wear to maintain stable mounting.

Usage recommendations

For consistent adhesion, avoid mounting on textured, porous, or curved surfaces. Regularly inspect suction cups for cracking or loss of elasticity and replace them in pairs to maintain stable attachment and accurate temperature reading positions.
