The Black and Decker TLD100 Thermal Leak Detector is a handheld diagnostic tool designed to help homeowners and tradespeople identify temperature anomalies caused by poor insulation, draughts, and air leaks around the home. Using thermal detection technology, the TLD100 scans surfaces and air currents to pinpoint both hot and cold problem areas. An intuitive LED indicator provides instant visual feedback — shining blue for cold draughts and red for warm draughts — making it straightforward to identify where heat is escaping or cold air is entering. The detector is well suited to checking window frames, door seals, loft hatches, and areas around pipework or electrical fittings. Adjustable sensitivity settings allow the user to fine-tune the detection threshold, and the selectable °C/°F measurement scale makes it a practical choice for a range of users. Ideal for energy efficiency surveys, pre-winter home checks, or identifying draught issues before remedial work begins.
