Brannan Digital Greenhouse Thermometer — Max Min Temperature Monitor for Indoor & Outdoor Use

Reliable climate insight for your greenhouse and garden

The Brannan Digital Greenhouse Thermometer combines a familiar max–min concept with a clear digital readout. It’s built to sit in greenhouses, conservatories, home gardens, or laboratories, giving you quick visibility into how temperatures shift throughout the day and night.

Designed for versatility, it operates in a wide span from -20 to 50°C (or -4 to 122°F). You’ll see the current temperature at a glance, while the device also records the highest and lowest readings since the last reset. This simple snapshot helps you understand microclimates, without waiting for external data or complex setups.

Why it fits your space

With a flip-out roof, it’s easy to protect the sensor from direct rain while keeping readings accessible. The slim profile means it won’t dominate a shelf or wall, and the included battery ensures you won’t need immediate replacements to start using it.

It’s a tool that supports informed decisions.
