Temperature calibrator PD-1020

for thermometersportableprecision

The PD-1020 is a compact, portable, and economical dry-well temperature calibrator designed for low-temperature applications. The unit features a cylindrical heating block and heat transfer sleeves, with a well diameter of 20 mm (0.79 inches). It can be powered by a 12V lead-acid battery, making it particularly suitable for scenarios without AC power supply. The calibrator comes standard with a carrying case and has a sales history of over 20 years, demonstrating proven reliability. It offers a temperature range from -20°C (-4°F) to 110°C (230°F), with a temperature stability of ±0.02°C per 10 minutes and a well depth of 160 mm (6.30 inches). Customized heat transfer sleeves can be machined to accommodate specific thermometer diameters. - Range (at 23°C ambient): -20 ℃ to 110 ℃ (-4°F to 230°F) - Working Area: Tapered Casing: Diameter 16mm (0.63"), Depth 138mm (5.4") - Casing Material: Aluminum - Temperature Control Method: Fully digital PID control - Display Resolution: 0.01 ℃ - Display accuracy: ±0.2 ℃ full range - Temperature Stability: ±0.02 ℃ /10min full range - Axial uniformity: ±0.04°C at –20°C(-4°F), ±0.02°C at 0°C(32°F), ±0.05°C at 100°C(212°F) - Heating Time: 8 minutes from 25°C(77°F) to 110°C(230°F) - Cooling Time: 20 minutes from 25°C(77°F) to -20°C(-4°F) - Stabilization Time: 5~8 minutes - Operating Voltage: 110VAC±10%, 60Hz or 12V, 7AH(Lead-Acid Battery) - Rated Power: Approximately 120W - Dimensions: 268mm (10.6") x 125mm (4.9") x 256mm (10.1") - Net Weight: Approximately 7.5 kg (16.5 lb)
