Hornady Digital Hygrometer 95909 — Touchscreen Temp & Humidity Monitor for Gun Safes

The Hornady Digital Hygrometer (95909) is a compact touchscreen thermometer and humidity gauge designed to monitor and record indoor temperature and moisture levels for gun safes, cabinets, and small storage spaces.

Keeping firearms, ammunition, and valuables safe from corrosion starts with knowing the conditions inside the storage space. The Hornady 95909 gives clear, on-demand temperature and relative-humidity readings on a large LCD touchscreen, stores high and low values, and offers flexible mounting so you can place it where measurements matter most. Small, battery-powered, and easy to read, this hygrometer helps you verify that dehumidifiers, desiccants, or climate controls are doing their job.

How does this hygrometer help protect firearms and metal gear?

By continuously reporting both temperature and humidity, the Hornady 95909 gives you the data needed to prevent moisture buildup that can accelerate rust. The device records 24-hour and all-time minimum and maximum values so you can track trends and react when conditions drift out of the safe range.

• Measures relative humidity and temperature in Fahrenheit or Celsius.
• Shows current, high, and low readings to spot problematic swings.
• Helps verify dehumidifier or desiccant effectiveness inside safes.
• Alerts you—visually—when conditions are outside desired ranges.

What features make the display and controls easy to use?

The 95909 uses a large touchscreen LCD that presents clear numeric readings and simple icons for mode and trend information. You can toggle temperature units and review recorded highs and lows directly on the device, without needing an app or extra equipment.

• Capacitive touchscreen for quick, intuitive control.
• Large digits for easy reading even in low light conditions.
• Displays both current and stored min/max values at a glance.
• Operates on two common AAA batteries—no special power source required.

Where and how can I mount or place the hygrometer?

The 95909 is built for versatility: set it on a shelf with the fold-out stand, attach it to an interior safe door using the quick-connect bracket, or place it in cabinets, workbenches, closets, or cases. Its compact dimensions make it easy to position where readings are most representative of stored items.

• Fold-out stand for freestanding placement on safe floors or shelves.
• Quick-connect bracket for secure vertical mounting on doors or walls.
• Compact footprint (about 5.125 x 3.25 x 1 inches) fits small storage areas.
• Lightweight and portable for temporary monitoring in vehicles or cases.

How does the 24-hour and all-time recording work and why it matters?

The monitor logs minimum and maximum readings over a 24-hour window and retains all-time extremes so you can identify daily cycles and longer-term shifts. This historical data is useful for diagnosing intermittent humidity spikes or temperature drops that can harm stored items.

• 24-hour min/max shows recent daily variations for quick checks.
• All-time min/max helps detect slow-developing trends over weeks or months.
• Stored readings enable better decisions about adding dehumidification or insulation.
• No external logging required—data is viewable on the unit itself.

Who is this for? The Hornady Digital Hygrometer 95909 is aimed at firearm owners, collectors, and anyone who stores metalwork, electronics, or paper valuables in small, enclosed spaces. If you use a gun safe, locker, case, RV compartment, or closet and want a straightforward, battery-powered way to confirm temperature and humidity, this compact touchscreen monitor provides the essential readings and recorded extremes needed to maintain proper storage conditions.
