The measuring device must only be operated in a non condensing atmosphere.
4 System Description
The PocketMonitor consists of an absorber and a display as well as an operating unit.
Both components are connected via a swivel joint. In a folded state, the absorber protects
the display as well as the operating elements from damages of any kind.
For the measurement, the absorber is exposed to laser radiation. The microprocessor
based electronics measures the temperature rise of the absorber by means of which
the power of the laser beam is calculated.
The 4½ digit display either shows the measured laser power or the temperature of the
absorber.
A lithium cell supplies the PocketMonitor with current for approx. 10,000 measurements.
Depending on the dierent power ranges, six dierent absorber versions are available.
The special version has a separate absorber.
