Temperature calibrator PD-4680

dry-blockhigh-temperaturefully-automatic

The PD-4680 is a high-temperature dry-well temperature calibrator. It employs a dual-zone heating system (upper and lower heating tubes) for precise temperature control, which effectively compensates for heat loss at the well opening. The calibrator offers a wide temperature range from 50 °C to 680 °C. It features a heating block with a diameter of 42 mm and a well depth of 200 mm, achieving a temperature stability of ±0.04 °C per 10 minutes. Operation and monitoring are facilitated through a color touchscreen that displays real-time data and temperature curves. An optional dual-channel electrical measurement module is available to meet diverse calibration needs. The unit is supplied with a sturdy carrying case for easy transport and storage. - Range (at 23°C ambient): 50 ℃ to 680 ℃ (122°F to 1256°F) - Working Area: Diameter 42mm (1.2"), Depth 200mm (7.9") - Casing Material: Copper Alloy - Temperature Control Method: Fully digital PID control - Display Resolution: 0.01 ℃ - Display accuracy: ±0.3 ℃ full range - Temperature Stability: ±0.05 ℃ /10min full range - Inter-hole ΔT: ≤ 0.3 ℃ at 650°C(1202°F) - Axial uniformity: ±0.1°C at 100°C(212°F), ±0.2°C at 650°C(1202°F) - Heating Time: 30 minutes from 25°C(77°F) to 600°C(1202°F) - Cooling Time: 180 minutes from 600°C(1202°F) to 100°C(212°F) - Stabilization Time: 10~15 minutes - Operating Voltage: 110VAC±10%, 60Hz (Customizable Technical Specifications) - Rated Power: Approximately 800W - Dimensions: 170mm (6.7") x 230mm (9.1") x 350mm (13.8") - Net Weight: Approximately 16 kg (35.3 lb) - Dual-zone heating system for precise temperature control - Wide temperature range: 50 °C to 680 °C - Heating block: 42 mm diameter, 200 mm depth - Temperature stability: ±0.04 °C per 10 minutes - Color touchscreen for real-time data and temperature curves - Optional dual-channel electrical measurement module - Supplied with a sturdy carrying case
