Faster, Easier & Accurate
The S291 Electronic Photofluorometer is specially designed to carry out fluorescence measurements faster, easier, and with higher accuracy. It has unique features like the zero and calibration adjustment with fine sensitivity potentiometer and digital display.
The S291 can also be used for ultraviolet and thermal stability tests on liquid penetrants. It can be used to measure the fluorescence of fluorescent and dual colored magnetic powders.
Measure of fluorescent brightness of penetrants as required by AMS 2644 (replacing MIL-I-25135), ASTM E-1417 (replacing MIL-STD-6866), EN ISO 3452-2. The NDT S291 is listed in ASTM E-1135 and completely meets the EN 571-2.
