BWR-4DD thermostat
delivery time：1 week
The
product uses a new generation of "multi-turn spring tube" as the
driving element, and the instrument greatly improves the temperature
measurement accuracy and service life. The all-stainless steel shell can
effectively protect the internal parts from environmental influences and dirt
intrusion.
