IRC 45 ... IRC 150

• 9 different types for fixed adjusted temperatures of 45°C, 70°C, 75°C, 95°C, 100°C, 110°C, 120°C, 140°C or 150°C
• High emissivity: 98%
• Large aperture diameter: 50.8 mm
• Short warm-up time
• High temperature stability
• Small dimensions
• Stainless steel housing

The calibration sources of type IRC 45 to IRC 150 are instruments for inspection of the measurement accuracy of pyrometers (radiation thermometers) at a fixed temperature value. The highly accurate controlling ensures a constant and stable heating of the large emitter surface with a high temperature uniformity with a maxium deviation of 0.2°C. This enables in combination with the high emissivity of the emitter surface at 98% also the exact verification of pyrometers with larger spot sizes.

The robust stainless steel design guarantees the operation even under rough industrial environments. The compact dimensions also enables the checking of fixed installed pyrometers at the measuring location.
