Zero Point Well
The PD-3000A is a specialized cold junction compensation (0°C) thermostatic device designed for thermocouple calibration. The bath is engineered with 11 precision wells of 7.5 mm (0.30 inches) in diameter, allowing users to insert glass tubes—enabling simultaneous cold junction compensation for up to 10 thermocouples under test and 1 reference thermocouple. By incorporating MPtest's jet-stream agitation technology, the temperature variation among the 11 wells is controlled within 0.02°C, significantly reducing the uncertainty of cold junction compensation.
