Large Volume High -Temperature Dry- Well
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.
