## Description

Round Digital Hygrometer with Adjustment Feature - Never wonder if your digital hygrometer is accurate. The HygroSet II is the first digital hygrometer of its kind capable of being adjusted after calibration. Each click of the adjustment knob changes the humidity display (+ / -) by 1-percent. Button cell battery included. Note: Quality Importers HygroSet II Round Digital Hygrometer is not compatible with exterior mount humidor models.

Review: Great product…and a starters tip… - Works great! Just follow the instructions that are included. In difficult cases (dryer air, colder temps, new or unused humidor) remember that you can jump start the humidity in your humidor by using a cotton ball to blot the inside walls and box top with humidifier fluid. This gets you up to 72% faster and takes the load off of the humidifier device.
Review: Accurate, reliable, long battery life, mounts anywhere - This is the third one of these I've gotten in just more than a year. They have been used in sheltered locations in blizzard conditions and in hot/humid situations where both the temp and humidity were in triple digits. In waiting a decent period of time before reporting the experience with them, I wanted to be able to give more than just a first impression. DESCRIPTION: The device itself is 1 3/4 inches diameter, 1/2 inch thick, with LCD readout (not backlit) that's 1/4 inch tall in a window 1 3/8 in wide x 3/8 in high. I think it's easy to read with adequate light. It's powered by a 357A button battery (less than 30 cents apiece if bought in a 10 pack on desertcart) which is accessed by a slide compartment on the back. The battery space is designed under the mounting area so it's easy to replace, although the original is still going strong after a year. MOUNTING: It comes with a crescent moon shaped magnet built into the back (it's lightly glued and can be removed if desired) and is quite strong and not easily dislodged from a decent metallic surface. An adhesive backed strip with a thin metal pad the same shape as the magnet is also included for use in placing a mount where a metal surface does not currently exist. The adhesive is rather weak and short lasting and I would suggest that double sided mounting tape be used if this method were chosen for a more secure fixture. There is no hole on the back for a nail hanging. FEATURES: The humidity reading is adjustable by a 3/8 inch diameter rotating dial on the lower right face. Each click of the dial moves the setting up or down 1%. The red button in the top center changes the temperature reading from Fahrenheit to Celsius and there is a small slightly recessed button on the lower left face that needs to be pressed to reset the humidity reading after the dial is moved. It's a safety measure I think because the dial is prominent and easily moved if the operator is not careful, or if children pick it up. Moving the dial without pressing reset does nothing. The temperature reading is not adjustable. RELIABILITY & ACCURACY: Straight out of the box all three of the ones I currently have were within 2 degrees of a calibrated laboratory thermometer at temperatures varying from 2 degrees F to 106 F. Over time they differ by only one or two degrees generally when placed within one foot of one another for a 24 hour period. Similarly, compared to a laboratory grade hygrometer, straight out of the box they were within 2 points reading humidity, and over time have maintained that degree of accuracy from an 18% to 100% saturated environment. It responds to small changes in temperature (less than 10 degrees) within 5 minutes and humidity (less than 20%) within 10. The main reason I chose this model over others was the adjustability of the humidity reading. Consumer grade humidity readers are notoriously inaccurate, even ones from famous "Scientific" manufacturers from Oregon. I did place each one in a 75% calibration environment (laboratory grade because it was available, but there are consumer ones available on desertcart that work fine for under $6) and each one read between 74 and 76%. So for the small sample size of 3 devices in my experience, none needed calibration. I tried the adjustment dial anyway, just for fun, and as advertised, one click = 1%. The clicks are subtle however, so be forewarned - you may turn the dial farther than you intend. The device responds quickly so it does not take long to correct your mistakes. Don't forget to push the reset button though, or your efforts will have been futile. SUMMARY: For the money this is really a very accurate and reliable piece of equipment. It has a major advantage over other humidistats in being adjustable. But I think its greatest advantage is that it comes from the factory actually calibrated, so it's accurate out of the box. For these type devices temperature has pretty much become a no-brainer - even $5 desktop penholders are pretty close. But I have found it rare that humidity readings are anywhere near accurate. For people looking for a temp/humidity sensor for wine cellars or cigar boxes or damp basements for determining when to run a dehumidifier, or dry air during the winter for a guide running humidifiers, this thing would suit well.

### ⭐⭐⭐⭐ Great little device for keeping tabs on the temperature and humidity!
*by J***H on February 20, 2015*

I purchased two of these devices to use in monitoring the temperature and humidity levels on different floors of my home. When I received them I placed them right next to each other and both continued registering the same values throughout the course of the day. These values also matched a larger thermometer that I had so I conclude that at least the temperature portion is accurate. The humidity portion also seems accurate, at least to the point that both units register the same value. These have built in magnetic backs so they are easy to attach to a file cabinet, refrigerator, etc. for easy monitoring. They also include an adhesive backed slim piece of metal so you can stick the metal on any surface and then the device will mount using the magnet as usual. All in all this is exactly what I was looking for. It's compact and does what I need it to.
