THERMASGARD
Calibratable surface-contact temperature measuring transducer THERMASGARD
eight switchable measuring ranges, continuous output, in an impact-resistant plastic housing with quick-locking screws, optionally with ⁄ without
display, cable sensor with a pipe feeder (ALTM 2), incl. strap.
The surface-contact sensor is used to detect the temperature on lines, pipes (e.g., cold and warm water) or on heating sections for heating control.
The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
