Two-Pack Aquarium Thermometer

This two-pack supplies digital thermometers built for aquariums, terrariums and vivariums. Each unit uses a submersible probe on a suction cup while the display stays dry. The bundle includes four suction cups and two LR44 cells ready to install.

Replaces Guesswork and Single Units

Swapping a single analogue strip for this pair lets you monitor two tanks or two zones in one system at once. The upgrade is worth it when you need simultaneous readings in fresh, tap, salty or marine water without moving a probe between setups.

Covers -50°C to +70°C with ±1°C Accuracy

The range handles tropical, temperate and cold-water setups from -58°F to +158°F. Readings stay within one degree Celsius across the span, but the probe-only immersion rule means the main body cannot go underwater.

Questions about this item

How is the probe secured inside the tank?

Each thermometer includes two suction cups; press the probe's cup against clean glass below the water line so only the probe is submerged.

Which button starts the unit and how do you turn it off?

Press and hold the PWR button to power on; hold the same button for three seconds to power off.

When will the LR44 cells need changing?

Replace a cell when the LCD dims or readings become erratic; each thermometer uses one standard LR44 button cell.
