Brannan Thermometers Limited

Brannan Thermometers Limited is a leading British manufacturer of thermometers, pressure gauges, and associated instrumentation products. Founded in 1913 by Sydney Brannan in south London as a glass medical thermometer maker, the company relocated to Cleator Moor in Cumbria during World War II. Brannan operates a highly mechanised manufacturing facility in England and a second plant in Sweden (acquired in the 1990s). The company supplies products to over 180 countries worldwide and holds a market-leading position in HVAC and industrial pressure gauges in the UK. Brannan's product range spans five sectors: industrial (pressure gauges, dial thermometers, digital meters, process instrumentation), scientific and education, catering, home and garden, and healthcare. The company operates one of the most technically advanced commercial temperature and pressure calibration laboratories in the UK, accredited by UKAS under ISO 17025. Key oil and gas applications include process instrumentation, pressure monitoring, and temperature measurement for harsh industrial environments. Brannan remains a privately owned, family-heritage business committed to British manufacturing.
