Aquarium Thermometer DT-A045

Aquarists and reptile keepers needing a simple

This unit is not for buyers who want continuous data logging, wireless alerts or a fully submersible display module. It also does not suit installations that require multiple probe inputs or calibration certificates.

Verify probe placement

The sensor probe attaches with suction cups and must stay submerged while the main body remains dry. Power comes from one included LR44 button cell; check that you can access the battery compartment for future replacement. Ensure the temperature range of -50°C to +70°C covers your environment.

Questions about this item

What size aquarium or terrarium wall will the 2.3" by 1.5" display unit fit against?

The thermometer body measures 2.3 inches long by 1.5 inches wide and stays outside the water; only the probe goes in.

Will the probe suction cups hold on the glass of my older acrylic tank?

The two included suction cups attach the submersible probe to smooth aquarium glass or acrylic surfaces.

How do I confirm the DT-A045 is reading correctly after I put the probe in the tank?

Power on with the PWR button, check that the large LCD shows a value between -50 °C and +70 °C, and verify the °C/°F switch works.
