## Summary description

TFA-Dostmann 30.1052.02 is an electronic indoor environment thermometer for measuring air temperature in °C and °F. Battery-powered (AAA 1.5 V) device suitable for home or office use, offering clear digital readout and straightforward operation for monitoring room climate and everyday temperature checks.

## Long description

The TFA Dostmann 30.1052.02 is an electronic indoor environment thermometer with a waterproof cable sensor for accurate temperature monitoring in refrigerators, freezers, aquariums and other damp or enclosed spaces. The digital display shows current temperature in °C or °F and records maximum and minimum values. An adjustable visual and acoustic alarm notifies you immediately when temperature goes outside preset limits. The compact display unit can be attached magnetically, fixed to a wall via a hanging slot, or placed on a surface using the integrated stand. The device is battery-powered (AAA) and designed for straightforward, professional use.
Advantages
The thermometer uses a high-quality waterproof sensor cable and precise measurement electronics to deliver reliable readings across a wide range from -40 °C to 70 °C. It stores and displays maximum and minimum temperatures, includes a configurable alarm with three volume settings (loud, normal, mute) and offers multiple mounting options (magnet, hanging slot, table stand) for flexible placement. The clear digital display and simple button controls enable easy operation and quick resetting of stored values.
Suitable for
Monitoring temperatures in refrigerators and freezers
Keeping stable conditions in aquariums and terrariums
Climate checks in laboratories, storage rooms, and food-preparation areas
General indoor temperature monitoring at home or in the office
When it may not be suitable
This thermometer is intended for indoor and damp-environment use with its waterproof external sensor; it is not designed as a standalone industrial probe for harsh chemical or high-vibration environments. It also relies on AAA battery power, so it may not be ideal where mains power or continuous long-term operation without battery replacement is required.

How to use
Place the display unit on a stable surface, attach it to a magnetic exterior surface, or hang it on a wall using the hanging slot. Position the waterproof sensor cable in the area you want to monitor—inside a refrigerator, freezer compartment, aquarium sump or other damp location—ensuring the cable and sensor are immersed or placed where temperature should be measured. Use the controls to select °C or °F, set alarm thresholds, and choose the preferred volume level or mute. The display continuously shows the current temperature and stored maximum/minimum values, which can be reset with the dedicated button.
What to consider before purchase
Required measurement range and the thermometer's −40 °C to 70 °C capability
Need for a waterproof external sensor and the approx. 2 m cable length
Power source: AAA batteries and expected battery-replacement intervals
Mounting options required (magnet, wall hanging, tabletop)
Required alarm functionality and available volume settings
Usage recommendations
For reliable readings, place the waterproof sensor where it is representative of the monitored environment (not directly against cooling elements or heating sources) and replace the AAA battery when low battery indication appears. Regularly check and, if needed, reset the maximum/minimum memory after adjustments to alarm thresholds or sensor placement.
