The PMA4100 Series Photostability detectors are process control detectors that have the capability of being calibrated in the field by the end user.

The PMA 4100-420 Detector System has two detector types, the PMA 4110-420 UVA Detector and the PMA 4130-420 Photopic Detector.  The detectors detect light from their respective spectral bands and send a current proportioned signal on a 4 – 20 mA current loop.  The PMA 4110-420 Detector is sensitive to the 320 – 400 nm spectral band and has a maximum (20 mA) sensitivity of 1.000 W/cm².  The PMA 4130-420 Detector is sensitive to the CIE Weighted Photopic spectral range, 480 - 620 nm, and has a maximum (20 mA) sensitivity of 5000 Lux. 

This detector system includes reference detectors, transfer calibrated from NIST traceable standards. One Reference detector is available to calibrate the Process detector for the Photopic range and one Reference detector is available to calibrate the Process detector for the UVA.  The software system can perform an in situ transfer calibration when connected via the USB.
