Clockswise Wall Thermometer and Hygrometer, 10-Inch

What to know

If you only need to check temperature, a basic thermometer may be enough. The Clockswise wall thermometer and hygrometer combines temperature and humidity readings in one large, round dial, which is more useful when you want both at a glance in a home, garden, greenhouse, or office. Its 10-inch diameter and bold numbers are intended to make quick checks easier from a distance, while the dial includes Fahrenheit and Celsius scales.

It needs no battery, so there is no battery to replace for its readings. The white finish also gives it a simple decorative look, though the product details don’t describe its materials or how it holds up to outdoor conditions.

How to use it

Place it where you want to monitor the room or area, then read the temperature and humidity from the dial. In a greenhouse, for example, a quick glance while tending plants can show both readings without checking separate instruments. The same combined format can be handy in an office or at home if you’re keeping an eye on more than temperature alone.

Keep in mind that no weather-resistance rating or care instructions are provided. Although it is described for indoor and outdoor use, don’t assume that means it is suited to every kind of direct exposure, choose its location with that missing detail in mind. The product information also doesn’t explain how to calibrate the readings, so this is best treated as a convenient visual monitor rather than a precision instrument.

Practical tips

Think about where you’ll read it before choosing a spot. The large dial is meant to be visible from a distance, but it still needs a clear line of sight, placing it behind objects or in a crowded area would undercut that benefit. For a greenhouse or garden, consider whether the location is sheltered, since no specific outdoor-protection details are supplied. Indoors, it can serve as a shared reference point when you want temperature and humidity together instead of relying on a temperature-only gauge.

The listed 10-inch diameter is a useful fit check: it gives the dial room for prominent numbers, but it also takes up more wall space than a compact monitor. The product description lists a 2-inch thickness as well. There are no supplied details about mounting hardware, so don’t count on a particular installation method being included.

Practical doubts

Does it need batteries? No. The product description says no battery is required.

Can it show both Fahrenheit and Celsius? Yes. Both temperature scales are listed on the dial, alongside the humidity gauge.

Is it intended for outdoor use? It is described for indoor and outdoor spaces, including a garden or greenhouse. However, no weather-resistance rating is given, so its suitability for exposed locations isn’t clear.

Should you buy it?

A solid pick if you want a wall-mounted, battery-free way to see temperature and humidity together, and have room for a large dial. It makes more sense than a temperature-only gauge when the humidity reading matters too, such as during a quick greenhouse check. Not the best choice if you need stated accuracy, calibration information, or confirmed protection from outdoor conditions, those details aren’t provided. The main trade-off is straightforward: you get a broad, easy-to-scan display, but less guidance about precision and weather exposure than a more fully specified monitor might offer.
