Pyrometer with LED display CellaTemp® PA 30

°Cwith laser pointerRS485

Product description
The CellaTemp® PA 30 is a digital single‑colour pyrometer for non‑contact temperature measurement from 400 to 2,500 °C. Its short spectral range (0.78–1.06 µm) provides increased accuracy on metallic targets. Sighting options include through‑the‑lens aiming, laser pilot light or an optional video camera. Emissivity, measuring range, smoothing and other parameters are configured via rear buttons and displayed on the 4‑digit LED; normal operation shows the current measured temperature.

Special features
