Two-pack aquarium thermometers

This two-pack supplies digital thermometers for monitoring water temperature in aquariums, terrariums or refrigerators. Each unit includes a probe on a 24.88 in cable and a main display measuring 2.17 x 1.46 in. The probes are 1.57 in long and the display body is 58×38×15 mm. The set is aimed at hobbyists who need simultaneous readings in two separate tanks or zones.

Probe placement and power

Attach each display unit outside the tank with the supplied suction cups and submerge only the stainless-steel probe. A single LR44 cell battery is included in each thermometer. Press the PWR button for three seconds to power the unit off when not in use. The external display keeps electronics dry while the probe handles fresh, tap, salty or marine water.

Sustained temperature tracking

The sensor delivers readings across a -50 °C to +70 °C range with a stated accuracy of ±1 °C. The large LCD updates continuously so gradual drifts are visible during long-term observation. Because the probe remains immersed and the display stays outside, condensation does not obscure the screen during extended operation.

Questions about this item

How far does the probe cable reach before the display unit must sit?

The probe cable extends 24.88 in, so the display unit stays outside the tank while the probe sits in the water.

Does the LCD stay readable and the battery last when the unit runs continuously in a warm tank?

The display is designed for constant immersion of the probe only; the main unit stays dry and the included LR44 cell powers the thermometer without active cooling.

What mounting hardware comes in the box so I can install both units right away?

Each of the two thermometers includes suction cups for the display and a submersible probe, so no extra parts are needed.
