Dry-block calibrator PD-2680

high-temperaturefully-automaticportable

The PD-2680 is a compact, portable, and economical dry-well temperature calibrator designed for high-temperature applications. It features a conical heating block and heat transfer sleeves. The large end of the heating block has a diameter of 25.4 mm (1.0 inch) and is manufactured from a high-temperature copper alloy that resists oxidation at temperatures up to 680°C (1256°F). This product comes standard with a portable carrying case and has a sales history spanning over 20 years, demonstrating proven long-term reliability. The calibrator offers a temperature range from 50°C (122°F) to 680°C (1256°F), with a temperature stability of ±0.03°C per 10 minutes, and a well depth of 160 mm (6.3 inches). Custom machining of thermometer bore diameters in the heat transfer sleeves is available upon request. - Range (at 23°C ambient): 50 ℃ to 680 ℃ (122°F to 1256°F) - Working Area: Conical Structure: Diameter 16mm (0.63"), Depth 160mm (6.3") - Casing Material: Copper Alloy - Temperature Control Method: Fully digital PID control - Display Resolution: 0.01 ℃ - Display accuracy: ±0.3 ℃ full range - Temperature Stability: ±0.03 ℃ /10min full range - Axial uniformity: ±0.05°C at 100°C(212°F), ±0.1°C at 400°C(752°F), ±0.2°C at 650°C(1112°F) - Heating Time: 30 minutes from 25°C(77°F) to 600°C(1112°F) - Cooling Time: 120 minutes from 600°C(752°F) to 50°C(122°F) - Stabilization Time: 8~10 minutes - Operating Voltage: 110VAC±10%, 60Hz (Customizable Technical Specifications) - Rated Power: Approximately 660W - Dimensions: 268mm (10.6") x 125mm (4.9") x 256mm (10.1") - Net Weight: Approximately 7.5 kg (16.5 lb)
