The all new 1928-C benchtop optical meter delivers unrivalled performance at a very competitive price for a benchtop optical meter. It can measure pulse, peak-to-peak and DC source measurements in units of W, dBm, dB, J, A, V, Sun, and relative units, either directly or as a measurement relative to a reference value. Its 4-inch full color, graphical LCD display enables both numerical and graphical representations of measurements.
This single channel benchtop optical meter is extremely versatile and sensitive, capable of measuring optical power ranging from 11 picoWatts to 20 kWatts, and optical pulse energy from 7 µJ to 20 kJ. All 918D Series semiconductor-based low power, 818P Series thermopile, and 818E Series pyroelectric detectors are fully compatible with the instruments and hot-swappable; there is no need of recycling the power when a different sensor has to be used.
The 1928-C optical meter is also equipped with several green features: the meticulously designed circuitry allows much lower energy consumption compared to the 1936-C model, eliminating the need for a cooling fan. It also features a Stand-by mode for further energy savings when the meter is not being used actively. The optical meter can be activated again with the press of ...

It also features a Stand-by mode for further energy savings when the meter is not being used actively. The optical meter can be activated again with the press of any button on the front panel. Finally, the meter can display irradiance in ‘Sun’ units, enabling photovoltaic researchers to use the power meter as a complementary tool to a reference solar cell.
