The mobile phone-sized Land Guide M4, a thermal imager, is available from Land Instruments International.
Incorporated into the design are features such as fingertip controls, thermal and visual images with voice annotation, on-board image processing, memory and USB connectivity.
With a sensitivity of 0.12 degrees C, the product detects small temperature differences within the measurement range -20 to 250°C and displays them as high-resolution, 16-bit thermal images.
The link with the target object is made by the digital images captured by the built-in visual camera, and a built-in laser locator that helps to pinpoint hot spots. To simplify the identification of potential problems, there are four measurement modes – simultaneous four-spot and four-area analysis, line profile and isotherm analysis – all of which can be saved as images.
The position and temperature of the hottest spot within the image is automatically tracked and indicated by a cursor, and 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 product 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 programme offers a range of temperature measurement, image processing and report generating functions.
