Economical Low-Temperature Dry-Well
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.
