Secondary and Industrial Lab Cells
Medium temperatures - fit into GEMINI R cavity These cells are suitable for the medium temperature cavities, and retain the full 65mm diameter. The cells contain 99.9999% purity metal giving a freeze or melt curve flat to ±0.01°C. The results, as seen by a radiation pyrometer, which are slightly sensitive to wall temperature, give an uncertainty of ±0.25°C. Easy replacement allows one piece of apparatus to work with any of the 4 cells. For smaller beam radiation pyrometers, orifice plates are available to reduce the aperture diameter to 50mm, 40mm, 30mm, 20mm or 10mm. Each reduction in aperture is accompanied by an increase in the effective emissivity. Apparatus and Accessory Details
