Digital Humidity + Temperature Gauge

Keep your guitars safe!
Knowing the humidity where you keep your guitars is absolutely crucial! This simple hygrometer is the first step to preventing expensive repairs.

Affordable, accurate, and essential
Too much or too little humidity will damage your guitars! If it’s too dry, woods will shrink and crack and frets will sprout. If it’s too wet, woods will swell and bulge, making braces come loose and more. Newly sprayed finishes will blush in high humidity environments too.

This digital hygrometer is super accurate (within 3%) and constantly measures humidity and temperature in Fahrenheit and Celsius. It also records the minimum and maximum readings so you can track dangerous spikes.

It measures relative humidity between 30%–90% and temperatures between 23°F–140°F (-5°C–60°C). Experienced luthiers and repair techs keep their shops at 40–50% relative humidity—this is where stringed instruments are the most stable.

It’s small enough to fit in any case and the large display is easy to read at a glance. Each hygrometer comes with a secure velcro mount—hang it where you spray, store your guitars, and anywhere you need to be sure your guitars are safe!
