Pro & Cons


  • Comes with built-In stand or mounting bracket
  • Temperature and Humidity Gauge
  • Designed for Industrial and Residential Usage


  • Not complete accurate



If you’re a home owner, it’s very important to know how humid the air is inside of your home. Humidity and moisture promote mildew and bacteria. These home invaders can lead to personal sickness, as well as an unpleasent experience for any visitors.

Additionally, humidity will encourage critters to enter your home. From crickets to centipedes to spiders, and pretty much every other creepy crawly that you most likely would prefer never enter the same shelter that you sleep in.

But if you live out of your car, then the ExTech Instruments Big Digit Hygro Thermometer may not be the best selection for you.

But aside from where you live, your career may dictate the usefulness of this little tool. If you’re a painter, then it’s important to keep an eye on how humid the air is. Too much humidity can prevent the paint from curing, or atleast delay it. And wet paint is never a good thing.

But if you’re a commercial or industrial painter, then the humidity in the air could actually make your job more difficult.  If you frequently use moisture cured urethanes, then your paint could be curing faster than you can apply it. if this is a foreign concept, then imagine using melted marshmellow paste as paint.

And that’s just the beginning for painters. Because temperature is always an issue too. If it’s too hot, then your epoxy can begin to cure before it’s spread over the floor. Or if it’s too low, then it might now cure at all.  And this is just one of the many professions where knowing what your relative humidity and temperature can be critical for a successful job.

But regardless of why you need this thermometer/hygrometer, it’s still an exceptional unit. It comes with a built-in stand and mounting bracket. So even if you don’t have a desk or table or stand to position it on, you can always secure it to a piece of equipment or machinery with the bracket.


Big digits

And they don’t call it Big Digits for nothing. With 1″ digital display, you can be keen and alert on what your readings are from where ever you are positioned. And not only is the display easy to read, it also has a memory function that allows you to review the previous humidity and temperature readings. But if the readings are becoming too abundant, then you can easily clear them and reset the memory for a fresh start.

And not only is the ExTech Instrument Hygrometer and Thermometer excellent at its job. It can perform even more detailed and accurate work when you combine it with the probe. The probe can be mounted directly onto the unit. It has a tether, which can be used to snake into a duct, or vent, or pipe, or anything else that a person would need to get a temperature or humidity reading from.


need it or not?

This verisitility, accuracy, and dependibility has made granted the ExTech Instrument as one of the most purchased hygrometers and thermometers on the market. And what makes it even more exciting is whether you’re purchasing it for a personal residence, a commercial building, and an industrial environment, you can buy with confidence, knowing that you’re thermometer will perform as a high-end product.

But even if you don’t need a thermometer or hygrometer hanging around the house or building, it could prove to a great acquisition after you install it. Maybe you’re seeing some creep crawlers in your house. Or maybe you’re sneezing more often. The hygrometer would be a great tool to help find the root cause. And if it is humidity, then a de-humidifier would be a complimentary purchase.

Or if you’re running a food manufacturing plant, you might have very sensitive ingredients that can’t get wet or moist. Then a digital hygrometer could help production save millions or dollars by preventing valuable product from getting destroyed.

And the benefits of the thermometer should be duly noted. However, the benefits of the thermometer and temperature readings are pretty obvious. If the room or facility is too hot, then it’s a dangerous working environment. Or if the room is too cold, then the working environment is also dangerous to both the person or the product.



So overall, even though the hygrometer and thermometer seem like impractical and unnecessary toys for people with more money than they know what to do with, they have proven time and time again that they are beneficial to health, safety, and production. So no matter which background you’re representing; the home-body, the busy-body, or the production-body, ExTech Intrument’s Big Digit Hygrometer and Thermometer can serve as a useful and beneficial tool no matter where you’re coming from or what you’re trying to prevent.
