Level Probes and Transmitters   Level Switches     Duff and Macintosh are “The Pressure Specialists” – in fact we thrive under pressure! With our pressure regulation equipment, we can solve some of the most arduous pressure regulator and sampling applications. With the Honeywell group of companies and Sensortechnics as our major suppliers, you can measure 1” WC to 200,000 psi! with customising to customer requirements our specialty. OEM and Industrial Pressure Sensors   Ultra Low Pressure Sensors   Custom & Industrial Press. Sensors/Assemblies Digital Pressure Gauges Electronic Pressure Controllers   With our suppliers, Exergen, ITI and Honeywell, we can provide many temperature and heat detection and measurement solutions. Heat Flux Transducers   Infrared Temperature Sensors     Starting many years ago with Ultrasonics, we moved away from a “dynamic” approach to a simple approach. This, combined with our Hot Spot and temperature detectors make us a simple supplier of quality equipment. Ultrasonic Leak Detection Equipment   Infrared Hot Spot Detectors   Liquid Bubbling Leak Detector Lenox have been in this business for many years. Their expertise was used in “The Manhattan Project” all the way to modern power stations and incinerators. Auto Blow-Down & Heat Recovery   High Temp Boiler & Furnace Video Systems   Boiler Water Sample Conditioning Started in 1924 (yes, they are even older than D&M) Sentry Equipment had developed reliable and economical devices for Boiler water and steam sample conditioning components and systems for both grab sampling and continuous measurement. Since 2003, Bristol Equipment joined Sentry to form a comprehensive group who know their industry, the applications and their equipment. Sentry’s equipment is a bench-mark for all equipment in the industry. For the best equipment available, you cannot go past us. Wet rack panels and components are our business. Coolers, pressure reducers and complete panels can be supplied. Exotic materials are our forte.
