Hot Particle Detector HPD 1/8

Detection of hot particles and glowing embers

Industrial  production  processes  often  create  hot materials or hot large masses without them glowing in a visible range. Coaly or sooty deposits within ducts or high volumes of comminution processes as they occur in exhaust ducts of hardening shops or foundries as well as in recycling plants,  for  example,  are  detected  by the HPD  1/8  detector.  The  HPD  1/8  detector reliably detects dangerous potentials in this low, non-glowing temperature range.
