The PocketMonitor (PMT) is a portable, easy-to-use power meter which has been developed specifically for use in everyday production environments. Key features are its compact and robust design and quick, straightforward use. Thanks to the solid aluminium housing, the electronics are protected from knocks and damp. In its folded-up state, the absorber shields the operating controls from damage. The microprocessor-based electronics measure the temperature of the absorber and calculate the power of the laser beam with a resolution of one watt. Thanks to the high resolution, measurements can be taken in a very wide power range with uniform accuracy. The exact power or the temperature can be selected on the large 4½-place display . The built-in lithium cell provides the PocketMonitor with current for around 10,000 measurements.
