Min-Max Thermometers

A min-max thermometer tracks the lowest and highest temperatures reached over a period, using small sliding index markers that stay in place after the column moves past them.

What is a min-max thermometer?

A min-max thermometer tracks the lowest and highest temperatures reached over a period, using small sliding index markers that stay in place after the mercury or alcohol column moves past them. A reset button returns the markers to the current reading, ready for a fresh 24-hour cycle.

SmartLabs stocks wall-mountable min-max thermometers, ideal for monitoring greenhouses, storage rooms, and cold storage where temperature swings matter.

Common uses of min-max thermometers in the lab

Where tracking a temperature range matters more than a single reading.

  • Tracking Extremes

    Sliding index markers record the lowest and highest temperatures reached since the last reset.

  • Resetting the Markers

    A reset button returns both markers to the current reading, starting a fresh monitoring cycle.

  • Storage Monitoring

    Mounted in a cold room or cupboard, a min-max thermometer confirms the space stayed within a safe temperature range.

  • Compare Case Styles

    Different housings suit different mounting spots, from a simple hook to a peaked, weather-resistant roof.
