Product information

Description

The TFA-Dostmann 30.3249.02 temperature transmitter is designed for indoor temperature monitoring within a range of -40 to 60 °C. It connects wirelessly with compatible TFA thermo-hygrometers and weather stations to provide remote temperature readings. The unit features a clear LED display and compact dimensions that allow discreet placement in rooms, cabinets or technical spaces where accurate ambient temperature measurement is required.

Advantages

This temperature transmitter offers a wide measuring range suitable for a variety of indoor environments, from cold storage to heated living areas. The LED display ensures readings are visible when accessing the sensor directly, while battery operation allows flexible placement without wiring. Its small size makes installation simple and unobtrusive, and wireless compatibility with TFA devices enables centralized monitoring and logging when paired with the appropriate receiver.

Suitable for

Monitoring room or equipment temperature in homes and offices
Supplementing TFA wireless thermo-hygrometers and weather stations with additional measuring points
Temperature monitoring in storage areas, closets or small cold rooms within the specified range
Use in technical rooms or near HVAC components to check ambient temperature

Key specifications

Measuring range: -40 to 60 °C
Display type: LED
Power supply: 1.5 V battery
Dimensions (approx.): 45 mm width × 25 mm depth × 125 mm height
Wireless transmission compatible with TFA indoor thermo-hygrometers and weather stations

How to use

Insert a 1.5 V battery and place the transmitter in the desired indoor location, avoiding direct sunlight and sources of radiant heat for representative ambient readings. Follow the pairing procedure of your TFA thermo-hygrometer or weather station to add the transmitter as an external sensor; once paired, temperature readings from the transmitter will appear on the base unit. Position the device at a height and spot that reflect the conditions you need to monitor, and periodically check the battery status to ensure continuous operation.

Usage recommendations

For stable readings, mount the transmitter in a ventilated area away from heaters, windows and doors. Replace the battery before the transmitter’s signal weakens to maintain reliable wireless communication with your TFA device. When using multiple external sensors, label each transmitter and register them in the base unit according to the manufacturer’s instructions to avoid confusion.
