LMT System Flash Meter SF105

l = 397

The System Flash Meter SF 105 is a universal precision instrument for the measurement of rapidly changing illuminances, e.g. flash lights. The system consists of an especially fast system-photometer head SP 05 F00 with a V(λ)-corrected Si-photoelement with built-in measuring amplifier and an electronic console SF 105. The system is able to measure rise times between 5 and 200 ms (the higher the intensity, the shorter rise times can be measured). The system stores 32000 values in its memory, which can also be stored as a standard ASCII-file. The system calculates numerous different characteristics automatically after the measurement. The characteristics contain for example the effective intensity of the flash.
