Fluke thermal imagers for preventative maintenance Fluke has launched two rugged thermal imagers the TiS55+ and TiS75+, suitable for carrying out preventative maintenance. Designed for one-handed use, the infrared inspection tools capture professional, high quality images of hot spots on machines and factory equipment, ensuring potential problems are caught before they lead to failures. Both the TiS55+ and TiS75+ provide a sharp, clear view of potential issues, and can be used by customers with no infrared imaging experience. Able to store around 500 images, the TiS55+ and TiS75+ come with built-in personal assistants that organise captured images and offer increased functionality by enabling users to add their own information.
