Increasing environmental and health concerns have encouraged the development of Brannan’s own unique mercury free maximum/minimum thermometers which replace the traditional mercury types, the standard design used for over 200 years. These products use a patented blue coloured liquid to replace the mercury but retain the ease of operation its predecessor had.

In addition to the traditional liquid-in-glass max/min thermometers, Brannan have a wide range of electronic max/min instruments suitable for indoor or outdoor use. These instruments can be supplied with certificate traceable to Recognised National Standard, if required. All are CE, WEEE and RoHS compliant.
