Digital Thermometer -58 to 230°F USB

USB-Powered Digital Thermometer

This USB-powered digital thermometer measures temperatures from -58 to 230°F (-50°C to +110°C) with ±1° accuracy. It updates readings every 0.25 seconds via a remote NTC sensor on a 1-meter stainless-steel cable. The unit operates on any DC 4–25V or USB 5V source, making it suitable for PC monitoring, aquariums, pet habitats, vehicles, and greenhouses. It is not for buyers who need a graphics card or video output.

Compact LCD Unit with Blue Backlight

The display measures 1.89 x 1.1 x 0.67 inches and features a built-in blue backlight for clear visibility in darkness. A selector switch on the rear toggles between Fahrenheit and Celsius units. The probe is rustproof 100% stainless steel (10k, B=3435K) and the 3.3 ft cable allows remote placement in ducts, tanks, or cases. It is not for users who require wireless logging, data export, or probe lengths beyond 1 meter.

Switchable Display and Versatile Mounting

Pulling or installing the shorting jumper on the back changes the temperature display unit between °F and °C. The unit can be flush-mounted or surface-mounted on any flat surface for a professional look. Power is drawn directly from a PC, laptop, power bank, or any USB port without an external adapter. It is not for applications involving corrosive liquids or environments outside the -58 to 230°F range.
