The Model S380 shares the convenient features of the Model S370, with the added flexibility of an additional channel. With the S380 you can measure two light sources simultaneously, or perform real-time ratio measurements.

Add the appropriate sensor head and the model S380 becomes a versatile, easy-to-use photometric, radiometric or fiberoptic power meter.

As the user programs each test parameter, the microprocessor provides step-by-step prompts via an LCD screen. The second channel is as easy to program as the first, since it is prompted and controlled similarly.

The S380 can be controlled by a simple, 10-function keypad or from a host computer via the IEEE-488 interface. Functions such as sending and receiving data, viewing operational data on the host computer’s monitor, and programming the S380 can be performed from a remote location.

The UDT Instruments unique plug-in calibration module enables limitless calibration. The module is an EPROM that is preprogrammed by qualified technicians in a UDT Instruments calibration lab. All calibrations are NIST-traceable and multiple modules are also available.

The S380 has five functions that eliminate tedious calculations. In “Linear”, the S380 can be used with any linear photodiode. “Log” permits attenuation measurements or measurements relative to a reference level. “Log Ratio” allows the user to set a measurement as a reference level to which other measurements may be compared. “Ratio” takes the ratio of a reference value to subsequent measurements. “Responsivity” permits the user to program the responsivity of any uncalibrated sensor head into the S380. The S380 also offers an analog output and an analog bar graph display on the front panel.
