Differential pressure measurement fast, simple and precise: This is what the testo 512-2 measuring device stands for, which measures pressures up to 2000 hPa. In practice, it is convincing due to its flexibility and application diversity. This means that the gas pressure on burners can be controlled just as quickly and precisely by measuring the gas flow pressure and the gas rest pressure, as is the testing of filters on air-conditioning systems. The position-independent differential pressure sensor thereby provides for reliable and highly exact measurement results. The testo Smart APP for smartphones and tablets supports you with these features: Configuring the meter, displaying graphs of measurements, saving measurement data, managing customers and measuring points, on-site documentation, e-mail delivery of the report.This text is machine translated.
