Small thermal imager, big benefits
The mobile phone-sized Land Guide M4, the world’s smallest and lightest thermal imager, is now available from Land Instruments International.
Features include: fingertip controls, high-quality thermal and visual images with voice annotation, on-board image processing, a large-capacity memory, and versatile USB connectivity. With a sensitivity of 0.12°C, the Guide M4 can detect minute temperature differences within a –20°C to 250°C measurement range and display them as high-resolution, 16-bit thermal images.
The link with a target object is made by the high-quality digital images captured by a built-in visual camera, while an in-built laser locator helps to pinpoint hot spots. There are four measurement modes to simplify the identification of potential problems — simultaneous four-spot and four-area analysis, line profile and isotherm analysis.
The position and temperature of the hottest spot within the image is automatically tracked and indicated by a cursor while a second cursor in the image centre is used to indicate the temperature and provide a reference for inspection analysis. An audible alarm is activated when the measured temperature exceeds a pre-set value.
The Guide M4 has a 1Gb memory for recording and on-board storage of over 5,000 files, each of which can include a thermal and visual image with voice annotation.
A Windows-based post-processing software program offers an extensive range of temperature measurement, image processing and report generating functions.
