We manufacture rugged, robust instrumentation kits to safeguard hard-working turbo-charged diesel engines.

Heat, in the form of excessive Exhaust Gas Temperature [EGT], is a common cause of failure in turbo-diesel engines, especially failure of the turbocharger itself. This is particularly relevant to vehicles which carry heavy loads or tow heavy trailers or caravans. Fitting and using an EGT gauge [Pyrometer] is an inexpensive way to safeguard your engine from expensive repairs due to excessive EGT.

Our primary product is the ThermoGuard EGT Gauge [Pyrometer] kit.

The ThermoGuard EGT Gauge is unique in that it provides a precise digital readout of EGT and includes, as standard, the facility to record and display the maximum temperature measured. An industrial-quality thermocouple and fittings are also included. Versions for both 12V and 24V vehicle systems are available.

This kit is suitable for most turbo-diesel engines including all popular 4WD and light truck engines. This kit contains all the components needed to install a fully functional EGT Gauge. It can be installed by a competent 'home mechanic' or any qualified diesel specialist.

The Boost Gauge!

Previous visitors to this site may recall that an electronic boost gauge for turbo-charged vehicles, with dynamic LED bar-graph display, has been "under development" for some time. We have assembled a small number of gauges to individual order and they seem to be performing well. However full roll-out of this product has been delayed by on-going difficulties sourcing suitable electronic pressure transducers at a reasonable cost. We will let you know when the gauge is available again.
