10 BEST HYGROMETER MODELS & WHICH TO GET FOR YOUR GREENHOUSE
One of the most important factors to consider when keeping a greenhouse or garden, either as a professional or a hobbyist, is to know how to manage the humid conditions of the place. Humidity is simply, the amount of water vapour in the air and this affects the moisture level in the greenhouse or garden. When the level of the water vapour is very high (too much humidity), condensation occur which can lead to transfer of diseases and growth of fungal pathogen such as Botrytis. Over the years, humidity plays a significant role in the choice of plant to keep in our greenhouses or gardens, because the plants can only thrive in conditions that are similar to that of their native region. However, technology has made it possible to be able to keep those plants you love while regulating the conditions required for them to grow well. This is made possible by the aid of a device known as a Hygrometer. Although, there are several hygrometers out there, this post will guide you on how to choose the best hygrometer for your greenhouse or garden!
FEATURES TO LOOKOUT FOR WHEN CHOOSING THE TYPE OF HYGROMETER TO BUY
As you are planning to purchase a hygrometer for your greenhouse, there are some factors you must check out before buying so that you can get not just the one that would suit your needs but the one that is also cost effective. Below are some of the key factors in no order of preference:
- ACCURACY: Getting a hygrometer that gives accurate reading is not really possible. However, it is advised to go for devices that monitor the changes in temperature and humidity with marginal error of about 3%RH (Relative Humidity).
- EASY TO USE: No one would love to get a device that is too difficult and complex to use. Hence, a simple or less complicated model that would not require many years of experience would be a better choice.
- AUTOMATED SWITCH FEATURE: Aside from considering the cost of purchasing the device, it is also necessary to go for the one that would not incur more expenses after purchase. For example, there are some hygrometers that does not have an auto shut off feature and this might cause the increase in your electricity consumption and bill. This auto shut off feature enables it to shut down automatically when not in use.
- SIZE: Are you bothered about the size of your greenhouse or garden space? If yes, then you don’t have to. This is because hygrometers come in difference sizes ranging from the one that could perfectly fit into your Cigar humidor to the one that can suit your larger greenhouse space!
- MULTIPLE SENSORS: There are several hygrometers that support multiple sensors which are connected to a master device. This is an added advantage for you if you have multiple rooms and you need to monitor the level of humidity and temperature at a go. Some hygrometers with apps do support this feature.
- DOWNLOADABLE APPS: Recent hygrometers now have apps to which they pair to, where you get information remotely delivered to your device! They do these either with Wifi and Bluetooth connection.

WHAT IS A HYGROMETER?
A hygrometer is a device that uses changes in pressure and temperature to determine the level of humidity in an environment. It is often referred to a humidity meter or humidity gauge.
Hygrometers are not only used to monitor greenhouse or gardening humidity. They are also used in ensuring food storage areas are moisture free, to monitor wine cellars, the level of humidity needed for one’s health and many more.
HOW IT IS USED?
Older hygrometer devices needs to be calibrated before use and also from time to time. However, recent technologies have developed new hygrometers that are already calibrated and are ready to use. Some of them might just require you connecting them to sensor after which you have downloaded the app that comes with it. You can then place the sensor wherever you want to check the humidity level and carry out the test!
TYPES OF HYGROMETERS AND THEIR USES
- ELECTRICAL / DIGITAL HYGROMETER: They use capacitance or resistance to measure the amount of humidity in the air. They read the humidity level by the amount of electric charge stored in the metallic plates (for capacitance) or ceramic plates (for resistance) when they are exposed to air. They are the most commonly used hygrometers. They are also fast and accurate.
- PSYCHOMETERS: This hygrometer consists of a set of twin thermometers – a wet bulb and a dry bulb. The decrease in temperature level in the wet bulb than that of the dry bulb indicates evaporation had occur. Humidity is the cause of the changes in temperature. Ideal for outdoor humidity.
- DEW POINT HYGROMETERS: They are used the measure the saturation of moist air in a gas. They are the most precise of all the different types of hygrometers. This is because they are used to determining the minute quantity of moisture.
Although, most people believe that the higher the price, the higher quality. It is however important for you to know that are very efficient. It is however, advised to check out for the one that would serve the purpose for which you are buying it efficiently regardless of the price.
