Zero Point Dry Well

PR540 zero thermostat is applied with the enhanced semiconductor refrigeration technology, the peak cooling rate can be up to 6℃/min, which can, only after 10 min at room temperature, be stabilized to 0℃ as required for calibration. It can provide a stable and accurate temperature field for the thermocouple reference end for an extended period of time and is an ideal replacement for the traditional freezers and is ideally suited for calibration of thermocouples or related instruments.
