Dual Display Digital Thermometer with Waterproof NTC10K Probe for Car and Fish Tank Use
This dual-display digital thermometer gives you accurate, real-time temperature readings in a compact panel-mount form. It is designed for monitoring environments such as car interiors, fish tanks, incubators, or any space where a reliable temperature check is needed. The device uses a waterproof NTC10K thermistor probe capable of measuring from -55°C to +120°C, providing a wide range suitable for both cold and hot conditions. With a resolution of 0.1°C, you can observe fine temperature changes that matter for sensitive setups. The dual 0.28-inch LED displays show two three-digit readings clearly, and you can choose between red+red or red+green colour combinations to suit your preference. Operating on a DC4-28V supply with low current consumption under 15mA, this thermometer is energy efficient and simple to install.
Features and Construction
The thermometer combines a clear digital readout with a robust temperature probe. The housing is sized for panel mounting, and the LED display is designed for easy readability even from a short distance. The probe is waterproof, allowing it to be used directly in liquids or moist air without damage.
Dual LED Display
Two separate 0.28-inch LED digital tubes each display three digits, giving dual readings simultaneously. The display colours are available in red+red or red+green combinations, chosen at purchase. The refresh rate is at least 500 milliseconds per cycle, keeping the readings current without flicker.
Temperature Probe
The included NTC10K probe is waterproof, enabling immersion in fish tanks, water baths, or outdoor environments. It measures across a wide range from -55°C to +120°C with an accuracy of 0.1°C. The probe connects via a 150mm power cord, giving flexibility in placement relative to the display unit.
Compact Panel-Mount Design
The main display unit measures just 48mm x 29mm x 22mm, making it easy to fit into dashboards, control panels, or enclosures. The recommended panel cutout size is 46mm x 27mm. The unit is powered by DC4-28V and draws less than 15mA, so it can run on a wide range of power supplies including car batteries or small transformers.
Uses and Placement
The thermometer is suited for any scenario where dual temperature monitoring is useful. Its waterproof probe allows it to be used in wet or damp locations, while the compact display fits into spaces where larger meters may not.
Car and Vehicle Use
Mount the display in your car dashboard to monitor external temperature, engine bay heat, or interior cabin conditions. The wide voltage range (DC4-28V) directly matches typical automotive electrical systems. The small panel size means it can be installed in spare switch slots or custom panels.
Fish Tank and Aquarium Monitoring
The waterproof NTC10K probe can be placed directly into aquarium water to measure temperature accurately. The dual display allows you to monitor two tanks or compare temperatures at different depths. The LED digits are bright enough to read through glass or plastic tank walls.
Workshop and Hobbyist Applications
Use the thermometer in incubators, terrariums, or small climate-controlled boxes. The 0.1°C resolution helps maintain stable conditions for reptiles, seedlings, or fermentation projects. The compact display can be mounted into a lid or side panel without taking up much space.
Benefits and Buying Value
This thermometer provides reliable temperature measurement with a clear digital readout at a low cost. The dual display gives extra flexibility, and the waterproof probe extends the range of usable environments. The device is straightforward to install and requires minimal maintenance beyond avoiding direct sunlight.
Reuse and Low Maintenance
Once installed, the thermometer draws very little power (under 15mA) and has no moving parts to wear out. The LED display has a long lifespan and remains readable for years. The waterproof probe can be cleaned with a damp cloth if needed, as long as the unit is powered off.
Why Choose This Product
This dual-display model offers a practical way to monitor temperature in two locations simultaneously, or to see both a reading and a setpoint. The wide measurement range and 0.1°C accuracy suit both everyday and precision tasks. The DC4-28V power compatibility makes it versatile for vehicles, boats, and home projects without needing an extra voltage converter.
