Stationary Pyrometers

CellaTemp PQ/PL Series

The CellaTemp PQ/PL compact pyrometers feature an integrated LED display. The temperature reading can be viewed even at a distance of several meters. Connect a USB interface to set parameters such as emissivity and smoothing function or to perform diagnostics from a PC. CellaTemp PQ models 27, 28 and 38 provide a patented LED spot light as a target marker. All CellaTemp PL models feature this LED spot light as well as focusable lenses. The LED spot light facilitates sharp focussing and indicates the exact size and position of the measured target spot.
