Extended Temperature Measurement Ranges up to 1500°C

Due to popular demand, the PREDATOR” Series of Thermal Imaging Cameras from General Tools & Instruments (General®) is expanding to include nine extended temperature range models. General’s GTi10, GTi20 and GTi50 are now available in models with temperature measurement ranges up to 600°C (1112°F), 1000°C (1832°F) and 1500°C (2732°F).

Ideal for revealing hidden heat-driven problems, General’s thermal imaging cameras detect very small temperature differences from a distance and convert an object’s invisible infrared radiation to a visible color image. These visual thermal images (called thermograms) with multiple temperature points enable the diagnosis of equipment malfunctions and poor performance far more effectively than single-spot conventional temperature measurement devices. Like the products in the original line, the new extended temperature range models offer outstanding benefits and value with a range of sophisticated features all at a best-in-class price.

These instruments can generate significant long-term savings by helping to quickly and easily:

  • diagnose heat exchanger, motor or compressor maintenance issues
  • locate invisible or inaccessible thermal leaks and pinpoint leak sources (e.g., in piping or ductwork)
  • inspect integrity of thermal insulation
  • reveal overheated electrical circuits
  • check/monitor combustion or temperature-controlled processes
  • assess the “thermal envelope” of any building and detect specific areas of energy loss
  • identify automotive issues like a misfiring cylinder, malfunctioning catalytic converter, clogged condenser, restricted refrigerant line, and hot spots signifying engine cooling system blockage
  • support maintenance and repair efforts by documenting problem areas


General’s thermal imaging cameras are a strategic investment and typically pay for themselves in a short period of time. The cameras’ manual focus, optional interchangeable lenses and high resolution provide more accurate images and assessments than competitive models. They generate powerful, convincing images (called thermograms) and related data that help technicians and contractors document findings, design solutions and convince customers or managers to authorize recommended repairs. Temperature data is displayed numerically and as an infrared colorized thermal image. The user can assign a range of colors to signify specific temperature ranges. In-camera analysis tools increase operator efficiency by allowing real-time access to and collection of all relevant temperature data. Included software enables more detailed temperature analysis and reporting.

General’s GTi10 model ($1,999 MSRP) offers the following top features:
