There are no features at all on this model. It’s either on or off, and if you read around in here, the hygrometer only works on some of them. It certainly didn’t work on mine. Unlike some of the units featured on this list, this Brannan thermometer doesn’t measure humidity, but it does still display the maximum and minimum temperatures. These are easy to read, displayed in numbers that are the same size as those displaying the current temperature. Resetting the max and min temperatures needs to be done manually, using a small button on the side of the unit.

Hygrometers measure the humidity of air or soil. You may want a hygrometer to measure the humidity of the air in a pet’s tank, or perhaps you are completing an experiment that requires a humidity reading. In addition, many people buy a humidity meters like hygrometer for their home to monitor the air quality for health reasons. Whatever reason you have for wanting a hygrometer, you have come to the right place for advice on choosing the best device for you. If you need to record changes in humidity, opt for a hygrometer that records data at certain intervals programmed by the user. For instance, some devices let you record the humidity every hour. On the other hand, perhaps you want a device that will monitor findings constantly. Either of these hygrometers is available. AccuracyOutdoor hygrometers are made for outdoor use and are more weather-hardy and durable than an indoor hygrometer. Choose the right one for the job at hand. Soil Some thermometers don’t mention any form of weatherproofing, in which case you should presume that they haven’t got any. For a greenhouse thermometer to be long lasting and effective, it should ideally at least describe itself as ‘water resistant’. The humidity temperature gauge displays all-time high and low records for both humidity and temperature Keeping a close eye on the temperature inside your greenhouse is vital for the health of the plants. Certain plants require different temperatures to flourish, and if the greenhouse is too hot or too cold, they will struggle to carry out necessary processes like photosynthesis. As mentioned, a lot of digital thermometers will provide max/min temperature readings as well as the current temperature. But why is this useful?

Even though the unit is compact, it still clearly displays humidity and temperature readings. On top of showing the current data, it also shows ‘low’ and ‘high’ readings from the last 24 hours, and indicates whether the humidity is considered ‘dry’, ‘comfortable’ or ‘wet’. It’s one of the best greenhouse thermometers if you need something small and compact. Plus, it has the added bonus of people able to affix to many different surfaces, depending on where will save the most space.

It is important to make sure that the hygrometer you choose is compatible with the power sources available in the location you want to place it. It will need an electricity source or a battery. Wi-Fi There are options to either hang the monitor, or prop it up on its own stand. Therefore, you can easily move it around and keep it on any surface, including shelves in the greenhouse.
