- Individually programmable user key - NOx measurements without heated sampling - 2 universal measured value inputs - 5 additional temperature inputs - Instrument air-conditioning for high measuring accuracy The ecom-KDheating diagnosis computer is a comfortable and extensively equipped, transportable measuring system for combustion installations. In addition to recording the measuring variables O2, CO, NO (option: NO2, SO2), T gas, T room and draught the device can also record up to five temperatures (e.g. flow and return temperature) and two analogue signals (e.g. oil and gas pressure). Long-term measurements are possible in automatic, unsupervised mode. All relevant data is saved in its chronological sequence on an RAM card. Via the built-in interface this data can be read out and processed further on the PC. The device is completely self-monitoring and is secured with the help of an electronic key to prevent operation by unauthorized outside parties. If the optional NO2 or SO2 sensors are used, there is no need for heated sampling thanks to the special removal technology for short-term measurements (also optional).
