Universal temperature controller, -50…+50 °C, hysteresis 0.5-5 K, internal setting

Electronic universal temperature controller. Various sensor designs allow universal use in heating, ventilation, air conditioning and refrigeration technology as well as in machine and apparatus construction. The heating status is indicated by a red LED. Sensors are not included in the scope of delivery. The sensor cable can be extended up to 100 m if a cable cross-section of at least 1.5 mm² is used.
