Brannan Digital Max Min Thermometer – Indoor/Outdoor Garden Temperature Monitor

Overview

Meet the Brannan Digital Max Min Thermometer, a compact, high-visibility device designed to keep an eye on ambient temperatures in both the garden and home. The large digital readout simultaneously shows the current air temperature while maintaining the day’s highest and lowest readings until you reset. Built to withstand real-world conditions, this thermometer covers a wide range from -10°C to 50°C with a precise 0.1°C resolution, making it useful for greenhouses, conservatories, or indoor spaces where temperature stability matters. Encased in a green ABS shell measuring roughly 30 x 50 x 180 mm, it complements outdoor walls and indoor shelves alike. A convenient keyhole slot enables quick wall mounting, so you can position it where you most often check the climate.

Performance, setup, and care

Performance is oriented toward simplicity and reliability. The device samples temperature roughly every 10 seconds, ensuring timely readings without constant attention. The max/min memory is retained until you reset, so you can observe trends over a day, a week, or a growing season. The unit switches easily between Celsius and Fahrenheit for regional convenience, and the included battery supports quick start right out of the box.
