LED pyrometer CellaPort PT 120

°C°FUSB

Product description:
The CellaPort PT 120 is a digital pyrometer for non-contact temperature measurement from 250 to 2,000 °C. Its wide measuring range and interchangeable focus optics make it suitable for diverse industrial applications. Through-the-lens sighting ensures precise target alignment. Emissivity, measuring range, smoothing and other parameters are adjustable via rear buttons and shown on the LED display.

• Measuring range: 250 to 2,000 °C
• Focusable interchangeable lenses for accurate distance adjustment
• Broadband anti-reflective precision optics
• 4-digit red LED display (digit height 8 mm) and multi-LED status indicators
• USB interface for data connection
• Rechargeable battery pack (approx. 15 h continuous at Ta = 23 °C)
