TFA 30.1009 Digital Maximum-Minimum Thermometer

The TFA 30.1009 is a digital max-min thermometer that measures indoor ambient temperature via integrated internal sensor and outdoor or remote point temperatures using a 3-meter wired external sensor. It is a practical solution for temperature monitoring in environments such as residences, offices, storage facilities, greenhouses, and refrigeration units.

The device's most practical feature is the max/min value indicator: the highest and lowest temperature readings recorded within a specified time interval are stored and can be displayed or cleared with a single button press. This enables retrospective monitoring of temperature fluctuations that occur throughout the day or overnight.

With a sensor measurement range of -50°C to +70°C, it is suitable for use in outdoor environments, refrigerators, and freezers. The indoor ambient measurement range is -10°C to +50°C. With +/-1°C accuracy, it provides sufficient precision for daily use applications. It operates on a 1.5V AAA battery with simple setup and operation.
