Mini Digital LCD Thermometer & Hygrometer (Round, Indoor/Enclosure Monitor)

Product Description

The Mini Digital LCD Thermometer & Hygrometer is a compact, highly reliable environmental monitor that is absolutely essential for any 3D printing and electronics workshop. Knowing the exact humidity and temperature of your workspace or material storage is critical, as moisture-degraded filament can lead to stringing, poor layer adhesion, and failed prints.

Measuring just 45mm across, this round gauge is specifically designed for flush-mount embedding. It easily snaps into a standard 41mm circular cutout, making it the perfect upgrade for custom 3D printed filament dry boxes, heated printer enclosures, or climate-controlled CNC control cabinets. The clear, high-contrast LCD screen provides instant, real-time readings of both the ambient temperature and the relative humidity percentage.

Batteries are included and pre-installed, meaning this ultra-portable sensor is ready to use the second you take it out of the box. Whether you need to monitor the moisture levels of your premium PETG and Nylon spools or keep an eye on the temperature inside a laser engraving enclosure, this tiny, wire-free tool delivers accurate data at a glance.

Key Features

• Batteries Included: Comes ready to use right out of the box with standard LR44 button-cell batteries pre-installed.

• Dual Monitoring: Simultaneously displays the ambient temperature and relative humidity percentage.

• Embedded Design: Features snap-in side clips designed to fit perfectly into a 41mm circular cutout for custom panels and dry boxes.

• Clear LCD Display: High-contrast digital screen allows for easy reading even from a distance.

• Compact & Lightweight: Small enough to toss directly into vacuum-sealed filament storage bags alongside your desiccant.

Applications

• Monitoring moisture levels inside DIY or commercial 3D printer filament dry boxes

• Tracking ambient heat inside enclosed 3D printers (like Voron or Bambu Lab machines)

• Environmental monitoring for workshop CNC control boxes and server racks

• General indoor room temperature and humidity tracking
