Professional digital thermometer and hygrometer TFA 31.1066.01
Professional digital thermometer and hygrometer TFA 31.1066.01
The TFA 31.1066.01 is a digital professional thermo-hygrometer for orientation and operational monitoring of temperature and relative humidity. The device design is suitable for manual measurements in the field and indoors, where climate conditions need to be checked quickly without installing a fixed monitoring system.
The device shows the current temperature and humidity on a display with backlight. For work in operational environments, the HOLD function is useful because it allows the currently measured value to remain shown on the display. The MAX/MIN function is used to display the highest and lowest values since the last reset.
The thermometer with hygrometer is suitable for checking the microclimate in warehouses, technical rooms, residential areas, greenhouses, workshops and operations where air temperature and humidity need to be monitored continuously or by spot checks.
Calibration option
If required, we offer accredited calibration of temperature and relative humidity in our own accredited calibration laboratory. A calibration certificate can be issued for the calibration. It serves as proof of measurement traceability and is suitable for operations where the control of measuring instruments must be documented.
Calibration is particularly suitable for companies, laboratories, warehouses, food operations, facility management or other workplaces where measured values are used for environmental monitoring, internal documentation or quality system requirements.

Instruction manual
Power supply and operation
The device is powered by two AA 1.5 V batteries, which are not included in the package. When the battery symbol appears on the display, the batteries must be replaced. The device should be switched off before replacing the batteries.
The thermo-hygrometer is intended for manual measurement. After inserting the batteries, it is ready for use and displays the current temperature and relative humidity.
Display and controls
The display shows the current temperature and relative humidity. The display also includes MAX/MIN value indicators, the battery symbol and the HOLD function.
The display backlight is activated by pressing any button. The backlight duration can be set to 1, 5, 10 or 15 minutes, with the default setting being 1 minute. The temperature unit can be switched between °C and °F.
