The 1.5M Mini Digital Thermometer Hygrometer is a high-accuracy, ultra-compact environmental sensor designed for localized monitoring in tight or specialized spaces. At Electrapac, we recommend this "mini" version for users who need the precision of a digital readout without the bulk of a full-sized weather station.

Product Overview

This device features a 1.5-meter (approx. 5ft) external waterproof probe, allowing the main LCD display to stay conveniently outside an enclosure while the sensor sits inside. It is the perfect tool for monitoring "micro-climates" where temperature and moisture levels are critical to the success of a project or the health of a pet.

Key Features for Electrapac Customers

• Panel-Mount Design: The rectangular housing features "snap-in" clips, making it ideal for embedding into a custom 3D-printed enclosure, a wooden cabinet, or a plastic bin lid.

• Extended Reach: The 1.5-meter cable gives you the flexibility to monitor distant or hard-to-reach areas while keeping the display at eye level.

• High-Contrast LCD: Designed for high visibility even in low-light environments, showing both temperature and humidity percentage simultaneously.

• Low Power Consumption: Runs for months on two tiny LR44 batteries, making it a "set-and-forget" solution for long-term monitoring.

• Waterproof Probe: The temperature/humidity probe is ruggedized to handle high-moisture environments like terrariums or steam-prone areas.

Setup & Installation Tips

To ensure your Electrapac sensor provides the most accurate data:

1. Probe Placement: For humidity monitoring, ensure the probe is not touching a wet surface or buried in soil; it needs airflow to measure relative humidity (RH) correctly.

2. Mounting Hole Size: If you are embedding the unit, use a cutout dimension of approximately 46mm x 27mm.

3. Battery Replacement: When the display becomes dim, simply slide the back cover off and replace the two LR44 batteries.

4. Avoid Direct Heat: While the probe can handle up to 70°C, the LCD display unit should stay at room temperature to avoid damaging the liquid crystal.

Primary Applications

• Reptile Terrariums: Ensuring your pets have the exact humidity and heat they need to thrive.

• Cigar Humidors: Maintaining a steady 70% RH to keep expensive cigars in peak condition.

• Incubators & Brooders: Monitoring egg-hatching environments where a 1-degree difference matters.

• PC Case Modding: Mounting the display on your computer case to monitor internal intake/exhaust temperatures.

• Dry Boxes: Keeping 3D printer filaments or camera lenses in a low-humidity environment to prevent mold or moisture damage.
