The DCP007 Series of industrial photometers (photo) can measure the concentration of light-absorbing substances over the wavelength of 280 to 2,000 nm. The new units use solid-state LED lamps and laser diode technology, and a dual wavelength, four-channel measurement technique enables the device to determine concentrations from high down to trace (ppm) amounts. All units are CE marked, IP65 housed, and ATEX-enclosure certified (I I 2 GD EExd-IIB-T5). Lamps have a typical lifetime of more than 100,000 h. Hall 10.1, Stand F20 – G21 — Kemtrak AB, Täby, Sweden
