مقياس الرطوبة من نوع كاليبر الغربي

Finally, a hygrometer that actually matches my other calibrated devices — the ±3% accuracy is spot on. I love that I can switch between Celsius and Fahrenheit with a single button. Makes monitoring my guitar humidor effortless.

I was skeptical about the +/-3% accuracy claim, but after a week of daily checks against two other gauges, this one is spot-on every time. The temperature display in Fahrenheit is a nice bonus for quick readings.

Finally a hygrometer that doesn't require a degree to set up—switching between Celsius and Fahrenheit took two seconds. The ±3% accuracy gives me confidence my guitar case is staying safe from humidity swings. Wasn't expecting such a clean digital readout for this price point.
