Temperature calibrator PD-4480

dry-blockprogrammablehigh-temperature

The PD-4480 is a large-aperture medium-temperature dry-well calibrator utilizing electric heating rods, achieving a temperature range of 50°C (122°F) to 450°C (842°F). Featuring a cylindrical well design with a diameter of 63.5 mm (2.5 inches) and a depth of 200 mm (7.87 inches), it offers interchangeable heat-transfer sleeves for versatile applications. The calibrator delivers a temperature stability of ±0.02°C per 10 minutes, with parameters displayed on a color touchscreen supporting multi-segment programmable temperature control. Additionally, a dual-channel electrical measurement module is available as an optional accessory. The unit includes a protective carrying case as standard. - Range (at 23°C ambient): 50 ℃ to 450 ℃ (122°F to 842°F) - Working Area: Diameter 63mm (2.5"), Depth 200mm (7.9") - Casing Material: Aluminum - Temperature Control Method: Fully digital PID control - Display Resolution: 0.01 ℃ - Display accuracy: ±0.3 ℃ full range - Temperature Stability: ±0.02 ℃ /10min full range - Inter-hole ΔT: ≤ 0.15 ℃ at 400°C(752°F) - Axial uniformity: ±0.1°C at 100°C(212°F), ±0.2°C at 400°C(752°F) - Heating Time: 60 minutes from 25°C(77°F) to 400°C(752°F) - Cooling Time: 120 minutes from 400°C(752°F) to 100°C(212°F) - Stabilization Time: 10~15 minutes - Operating Voltage: 110VAC±10%, 60Hz (Customizable Technical Specifications) - Rated Power: Approximately 600W - Dimensions: 170mm (6.7") x 230mm (9.1") x 350mm (13.8") - Net Weight: Approximately 13 kg (28.7 lb) - Large-aperture medium-temperature dry-well calibrator - Temperature range: 50°C to 450°C (122°F to 842°F) - Cylindrical well: 63.5 mm diameter, 200 mm depth - Interchangeable heat-transfer sleeves - Temperature stability: ±0.02°C per 10 minutes - Color touchscreen with multi-segment programmable control - Optional dual-channel electrical measurement module - Protective carrying case included
