Brannan & Sons has manufactured and supplied thermometers, gauges and instrumentation since 1913.
Over a century of tradition, combined with modern manufacturing methods at our facilities in the UK ensure unequalled service.
The Company has operated a quality management system since 1991 and currently operates within the scope of ISO 9001: 2008.
Complimenting our production facilities, the Company provides a calibration service operating its own UKAS accredited laboratory where, in addition to having new thermometers tested, customers may also have existing instruments re-calibrated.
Following the 2014 EU ban on mercury, a wide choice of electronic instruments and organic, non-hazardous filling materials, including our Patented LO-toxTM fillings, are available.
