People who value a healthy indoor climate and high energy efficiency can use the PTD 1 thermal detector from Bosch in future. It can be used to quickly and easily detect what are known as thermal bridges and mold risk areas. Thermal bridges are areas of the building where heat escapes and energy is lost. Typical examples of these are poorly insulated windows or uninsulated areas of outer walls. Depending on the mode selected, the tool measures room temperature, surface temperature of walls and objects, and humidity. It then assesses these readings in relation to each other and interprets the data. This is made possible by three sensors and Bosch-developed software. The result is presented to the user in a traffic light system using three LEDs: red means “there is an high risk”, yellow means “there is an increased risk”, and green means “there is no risk”. This reveals critical positions in seconds, and the user can then take action to make their home more comfortable and energy efficient.

Easy measurement for quick results
The thermal detector is easy to operate and has only a few buttons. It works in three modes:
· In Mode 1 the tool measures the surface temperature of walls and objects, for example radiators, with a measuring accuracy of ± 1 degree Celsius. This enables you, for example, to determine whether radiators are working properly.
· In Mode 2 the PTD 1 detects thermal bridges by taking various temperature readings.The tool uses a red LED to warn you when it discovers hot or cold draughts.
· In Mode 3, to locate a mold risk, the thermal detector measures the room and surface temperature and the humidity with an accuracy of ± 2 percent. It uses these three readings to locate mold risk areas. The tool uses a red LED to warn you when there is an acute risk.

The exact measured values can be quickly and easily read on the illuminated display. Easy-to-understand symbols show each operating mode, the battery status and the unit of measure in degrees Celsius or in percent if it is humidity. The measuring field is indicated on the wall or object by a laser circle. The maximum working range of the PTD 1 is five meters, and the optimum measuring distance is one meter. This thermal detector sits comfortably in your hand during every measurement due to its classic pistol-grip shape. The tool is switched on either using a button on the control panel or using the switch on the handle. The illuminated display then instantly lights up and the PTD 1 will automatically be in the most recently used mode. The thermal detector is powered by two standard AA batteries.

The PTD 1 thermal detector will be available from October 2012 onwards at the recommended retail price of 129.99 euros including VAT.
