PHOTOCALORIMETER ACCESSORY

The improved Photocalorimeter Accessory (PCA), for the Q2000 and Q200 DSC, permits characterization of photocuring materials between -50 and 250 °C. UV/Visible light(250-650 nm) from a 200W high pressure mercury source is transmitted to the sample chamber via an extended range, dual-quartz light guide with neutral density or band pass filters. Tzero™ technology permits direct measurement of light intensity at both the sample and reference positions. It also provides for simultaneous measurement of two samples.
