Key benefits Provides a direct relative humidity (RH) reading so you can monitor and protect cigars and other humidity-sensitive contents. Designed for installation into a humidor by drilling, enabling a clean, integrated appearance and permanent monitoring. Metal construction offers durable long-term use in a humid environment. Rear-mounted reading keeps the visible face neat while the RH indication is accessed from the back. What it does Reads relative humidity (RH) inside your humidor. The hygrometer is used to measure the humidity of the humidor. Humidity is read from the back of the unit, allowing installation flush into the humidor wall. Key attributes Function: Measures relative humidity (RH). Compatibility: Intended for use in humidors where a drilled mounting hole is acceptable. Material: Metal housing for durability and resistance to handling. Readout orientation: Rear/back reading for integrated installations. Practical applications Building a custom humidor: Drill the required hole and install the hygrometer for a permanent, integrated humidity monitor. Retrofitting an existing humidor: Replace an older unit by drilling a small hole and mounting this rear-read hygrometer to maintain accurate RH awareness. Routine humidor maintenance: Use the unit to confirm humidification system performance and make adjustments to keep cigars at the desired humidity. Installation notes Ideal for drilling holes in any humidor; plan the hole location so the back-mounted readout is accessible after installation. Ensure the mounting hole matches the hygrometer’s dimensions for a snug, secure fit (verify dimensions before drilling).
