Criteria for Choosing the Best Hygrometers
Before venting out or starting to scour the Internet in a desperate search for the best or most suitable hygrometer, it’s important to take several factors into consideration. In addition to cutting down the time and effort you’d otherwise expend on the endeavour, it also ensures you get one that’s most relevant to your scope of application. Some of the crucial factors to keep in mind include ease of use, pricing, performance – including accuracy, and battery life, among others. The idea is to narrow down your scope, eliminating unsuitable matches until you end up with one that best meets your requirements.
The scope of Application/Use
The most critical consideration in your search for a hygrometer is the intended use. Different people buy hygrometers for different purposes, and it’s this difference in intended use that informs the different model sizes and accuracies. For domestic and light-duty to medium-duty commercial use, any mid-sized hygrometer should do the trick. Users running high-end commercial establishments or those with private wine cellars and cigar humidors appreciate the need for investing in military-grade and dead-on accurate hygrometers. Consequently, they will not settle for anything less than the highest quality hygrometers capable of simultaneously monitoring temperature and humidity changes all through the day and keeping the highest and lowest records for several days for purposes of analysis and forecast.
Since this piece is intended to guide homeowners in choosing a most suitable hygrometer, we’ll insist that you consider whether you need monitoring in several rooms and whether you’ll need remote monitoring. In the same vein, it would be prudent to go for a hygrometer with remote monitoring if you occasionally travel out of town but don’t want to leave anything to chance.
Measurements and Accuracy
Contemporary hygrometers also provide the option for simultaneously monitoring the levels of temperature in addition to humidity. With regard to measurements, consider the range you want to work with. High-end models make it possible for the user to monitor humidity from a range of 0% to a high of 100%. While this is obviously impressive, it may be beyond the scope needed for domestic use. A range of between 20 and 90% is more sufficient for everyday use around the house. The same goes for temperature monitoring. The vast majority of modern hygrometers are capable of working within a range of between 32ºF and 122 ºF, the equivalent of 0ºC to 50ºF. As for accuracy, something with up to ±4% RH should be sufficient. For commercial applications, try and limit that to ±1% RH.
Ease of Use
Like all other handheld machines, the manufacturers of hygrometers tend to ensure they are both practical and easy to use, at least for the most part. To this end, the machines come with a wide assortment of convenience features that aim to take away the time, effort, and guesswork away from monitoring temperature and humidity. As a result, it is not surprising that most hygrometers have large LCD displays to make the data easy to see and read from across the room and from multiple angles. High-end models even have a backlight to illuminate the readout in dimly lit environments properly. Consequently, you still get to use the hygrometer thermometers all throughout the day and night.
A second convenience feature is the ability of hygrometers to store the highest and lowest temperature and humidity data recorded over a 24-hour period. In addition to providing all round the clock monitoring, the data saving option also makes it possible for the user to compare data over several days, which can help predict conditions over the next few days, thereby eliminating any surprises. Thirdly, if the machine comes with several sensors, you’ll be able to monitor multiple rooms simultaneously, helping you know the rooms that are hottest or most damp. To these features add the ease of installation. A hygrometer should be easy to mount on different surfaces. Those with foldout stands can go on any flat surface while the ones with magnetic backings mount easily and quickly on metal surfaces.
Yet another important consideration is how pricey or pocket-friendly a hygrometer is. As a rule, high-end models with all the bells and whistles command a higher price compared to their off-brand, run-of-the-mill counterparts. However, before committing your hard-earned money, consider whether the unit has the most basic features and accuracy that will make your work easy and painless. Those with remote monitoring might be expensive, but in the long-run, they’ll make your work much easier. In the same breathe, its pointless pouring lots of cash on an expensive model when you only need something practical and functional for occasional use around the house. The decision boils down to personal preferences, anyway.
Frequently Asked Questions
Q: How do I calibrate my hygrometer?
A: The need to calibrate or re-calibrate a hygrometer is an important one. Even though there are varieties out there that come already calibrated, doing it yourself leaves no room for errors in measurement as it ensures accuracy at all times.
