SMARTRO SC92 Professional Indoor Outdoor Thermometer - Pro Accuracy

Our review of the SMARTRO SC92 finds it best suited for people who need reliable, repeatable indoor and outdoor temperature and humidity readings without fuss. The biggest reason to buy is its combination of a world-leading Swiss sensor and pre-calibration that together deliver highly accurate measurements across extreme conditions; anyone monitoring a greenhouse, nursery, wine cellar or baby room will appreciate readings that stay within tight tolerances. Setup and daily use are straightforward, and the large backlit screen makes data easy to read in dim locations.

Key Features

• Swiss sensor accuracy: The built-in world-leading Swiss sensor tracks subtle humidity and temperature shifts so readings remain consistent across diverse environments.
• Wide condition tolerance: Designed to tolerate arctic cold, scorching heat and high jungle humidity so values stay within 0.5F and 2% RH in many situations.
• Pre-calibrated with manual calibration: Ships pre-calibrated for accurate use out of the box and supports manual calibration to restore accuracy if readings are impacted.
• Multi-sensor support: Wireless transmission lets you connect additional sensors so the display can show readings from up to four locations up to 200ft apart.
• Large backlit display: The 3.5-in HD LCD and one-touch backlight provide clear, power-saving visibility and large numbers that are easy to read in low light.
• Flexible placement: Retractable stand, magnets and wall-mount hardware make it simple to place the unit in a baby room, closet, greenhouse or basement.

Who It's For

The SMARTRO SC92 is an excellent pick for hobby gardeners, greenhouse keepers, wine collectors and parents who want a reliable indoor/outdoor view of temperature and humidity with professional-level accuracy. The ability to add wireless sensors makes it a good match for anyone who needs to monitor multiple zones such as a cellar and living space or storeroom and office.

Users who want a simple single-sensor budget gadget may find the SC92 more feature-rich than necessary, and people requiring integrated smart-home cloud logging or app-based alerts should look for networked models instead.
