Environmental Meters, Thermometers and Weather Stations

Brannan offers a wide variety of environmental meters, thermometers and instruments which measure Wind Speed; Sound Levels; Light; Humidity; Moisture and Temperature. Our hand held devices are robust, accurate and easy to use, and are supplied in complementary large or compact sizes depending upon customer preference. Our large size professional range comes in a handy carry case. Clear LCD screens are simple to read, and the range is fully compliant with CE standards.

A traceable calibration certificate is provided as standard with each digital environmental meter and measurement device, and further calibration is available if required. We also offer analogue liquid-in-glass whirling and fixed (Mason’s) hygrometers to measure atmospheric water vapour on a percentage scale known as Relative Humidity (%RH). The difference between the “wet” and “dry” bulb temperatures enables the %RH to be determined through the use of a tables or a calculator. Finally, our popular range of digital indoor / outdoor weather stations complements the range.

Trusted for over 100 years.
