Over 25 years' experience in instrumentation and control systems for industry.
ThermoGuard Instruments was established in 2003 by Ian and Annette Petersen. Ian is a qualified electrical engineer with over three decades experience in instrumentation and control systems for industry.
In 2001, Ian and Annette purchased a 1997 Land Rover Discovery turbo-diesel 4WD (300Tdi engine) which they since used using for extensive travels across Australia, with a well-loaded caravan. With his usual enthusiasm for technical knowledge, Ian set about extending his knowledge of turbo-diesel engines - what makes them work and how to get the best out of them.
This soon led to confirming the importance of EGT measurement - without doubt, the most critical measurement to ensure the efficient and safe operation of a turbo-diesel engine. Using his industrial experience, Ian designed an EGT gauge for his own vehicle, using industrial-quality components. Some 17 years and 320,000 km later, this first gauge is still performing trouble-free. Shortly after completing this first gauge, he began producing kits for other 4WD enthusiasts.
During 2003, during a 12 month 'working holiday' in Alice Springs, demand for the kits grew to the point where they registered the business name, obtained an ABN and began thinking about the website, which came 'on-line' in 2004.
In 2003, Ian completed a module of study in Diesel Fuel Systems Service and Repair at Centralian College, Alice Springs, Australia, and private study including Bosch diesel fuel injection system manuals.
As ThermoGuard Instruments is now based on a rural property in SE Qld, personal collection of EGT gauge kits is not practical. All products are delivered by postal services.
