Large Volume Medium-Temperature Dry- Well
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.
