Excerpt: be sure - Flue gas analyzers from Testo
Measuring instruments are often exposed to demanding or harsh environmental conditions in daily use. It is not uncommon for gas analysis sensors to be temporarily overloaded by extreme temperatures or gas concentrations beyond the specified measuring range.
Mechanical impacts, such as dropping the instrument, cannot be ruled out either. In addition, dirt and material deposits can impair its function over time.
Pulse test analysis is used to determine whether measurement readiness is still complete after such events. The sensor is enabled to check its functionality independently at regular intervals.
The pulse test analysis provides an integrated self-monitoring function which regularly checks the readiness of the sensor for use and ensures its proper functioning. As a leading manufacturer of measuring instruments, Testo develops and produces both the actual gas sensor technology and the evaluating electronics of the instruments.
Comprehensive know-how and access to all aspects of the measurement process are thus available for research into new sensor functions.
Currently, Testo is working on the development of a pulse test analysis integrated into the measuring instrument. The automatic sensor self-monitoring runs in the background and has no influence on the use of the instrument.
