TFA have thought of everything when designing this sleek window thermometer. The large, clear display of current temperature is easy to read from indoors, even at night thanks to the time-controlled auto backlight, illuminating the readings if dark between 5am and 9am, and 9pm and 11pm. This feature can also easily be turned off with Eco mode.

The Vision thermometer displays both min and max temperatures, which are auto-reset at convenient times. Maximum temperatures are rest at 8am to capture day-time highs, and minimum temperatures are reset at 8pm to capture night-time lows.

Choose between Celsius or Fahrenheit, and pop the handy clock into DST mode with the touch of a button.

We recommend charging the rechargeable battery in your solar thermometer on a sunny day before first use, or using a rechargeable battery charger.
