Company Profile

G. Lufft Mess- und Regeltechnik GmbH, located in Fellbach near Stuttgart, has been Developing and producing professional components and systems for climate and environment measurement for more than 130 years.


The precision workmanship of highly skilled specialists has enabled the LUFFT label to be known and the products to be purchased worldwide. Intelligent meteorological sensors form the basis of highly available measuring networks along roads, rail and at airports all over the world. Meteorological services and environmental bodies appreciate the precise and longlasting Lufft quality as do building equipment manufacturers and energy suppliers as well.


Lufft underlines its claims to high quality by operating its own calibrating laboratory. This laboratory contains an accredited wind tunnel in which all wind sensors are tested thoroughly before delivery.


LUFFT products and equipment are to be found wherever atmospheric pressure, temperature, relative humidity and other environmental factors require to be measured or recorded.


We are certified according to DIN EN ISO 9001.

Lufft OPUS 20 TCO Data logger

The amount of carbon dioxide had been virtually constant at 280 ppm (particles per million) – i.e 280 gas molecules per million air molecules – the last ten thousand years. However in recent years, this measured value has been increasing rapidly at approx. 2 % per year.

A high level of CO 2 in the air within a room causes headaches, tiredness and lack of concentration. The regulation on CO 2 concentration was established in order to evaluate IAQ (Indoor Air Quality). Normal atmospheric air in so-called ‘clean air areas’ has a level of 360 ppm and approx. 500 ppm in urban areas. The limit of 1,000 ppm (“Pettenkofer Figure”) is still seen as being adequate indoor-air quality, which is especially important when regarding all meetings and conference rooms, as well as schools and open-plan offi ces. As a guideline for school rooms in the USA the limit of 1,000 ppm applies; for workplaces the occupational exposure limit is 5,000 ppm.

WS501-UMB Compact Weather Station

WS501-UMB Compact Weather Station for measuring of air temperature, relative humidity, solar radiation, air pressure, wind direction and wind speed. Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. The world renowned technology of Kipp+Zonen CMP3 is integrated. Ultrasonic sensor technology is used to take wind measurements. Measurement output can be accessed by the following protocolls: UMB-Binary, UMB-ASCII, SDI-12, MODBUS. One external temperature or rain sensor is connectable.

Ultrasonic Anemometer Ventus-UMB

Extremely precise and maintenancefree measurement of wind speed, wind direction and air pressure as well as calculation of acoustic virtual temperature. The ultrasonic wind sensor is designed without mechanical parts as known with traditional "cups and vane". The digital or analog output delivers instantaneous, average, min or max value with flexible measuring rate.

The Ventus-UMB is heated in case of critical ambient conditions. Made for cold climates! Recommended for: Wind turbines, marine/ships, meteorology and building automation.
