DORHEA Aquarium Thermometers, 20-Pack with LCD Display and Submersible Probe

DORHEA aquarium thermometers are a 20-piece set for monitoring water and liquid temperatures, with an LCD display and a measurement range of -58°F to +158°F (-50°C to +70°C).

• 20 aquarium thermometers — equip multiple tanks or keep units available for different setups.
• Measures from -58°F to +158°F (-50°C to +70°C) with ±1°C accuracy — monitor a broad range of temperatures.
• LCD display with a °C/°F switch — choose the temperature scale you prefer.
• Submersible sensor probe — take readings in water while keeping the display unit dry.
• Two suction cups — attach the display and probe separately.

Keeping track of water temperature is useful in aquariums and other setups where temperature readings matter. DORHEA thermometers are suited to water and high-moisture environments, including terrariums and vivariums, and can also sense the temperature of different liquids. Their separate probe and display make it possible to place the sensor where a reading is needed while keeping the main unit out of the water.

Which water types can these thermometers measure?

DORHEA aquarium thermometers can measure temperature in fresh water, tap water, salty water and marine water. The sensor is also suitable for temperature sensing in many types of liquids, making the set useful beyond aquarium water.

• Made for use in aquariums, terrariums and vivariums.
• Suitable for water and high-moisture environments.

How do you set up and read a DORHEA thermometer?

Press the PWR button to turn the thermometer on, place its sensor probe in the water and read the temperature on the LCD. Use the button to switch between Celsius and Fahrenheit; press and hold PWR for 3 seconds to turn the unit off.

• One suction cup holds the display against the side of the aquarium; the other secures the probe.
• Clean the suction-cup surface to help it adhere.
• Only the sensor probe is waterproof; keep the main display unit away from water.

What comes in the 20-piece set?

The set contains 20 DORHEA aquarium thermometers. Each thermometer has an LCD display and a sensor probe, so the probe can be positioned in the liquid while the display remains outside it.

• Temperature accuracy: ±1°C.
• Temperature units: Celsius or Fahrenheit, selected with the button.

This set suits aquarium, terrarium and vivarium keepers who want to monitor temperatures across several setups, as well as users measuring the temperature of liquids. It is designed for probe-in-water readings, not for submerging the display unit.
