Accessories	Description & Features
Digital Recorder	6 channel or 12 channel The digital recorder is commonly used in stress relieving and critical preheat applications. The recorder stores temperature data based on time. It is not required to perform successful heating applications.
Post Weld Heat Treatment Blanket	Post Weld Heat Treatment Blanket The blanket efficiently insulates and optimizes the coupling distance between the coil and the workpiece, safeguarding the liquid-cooled cable. Its fully enclosed, sewn design also reduces dust, creating a cleaner and more conducive work environment.
Thermocouple & its accessories	Directly welding thermocouples onto the heated part offers unparalleled accuracy in monitoring and controlling temperature during the heating process, making it the most precise method for recording temperature data. Thermocouple wire, 150 m Thermocouple connectors (10 pack) Thermocouple attachment unit Thermocouple Extension Cable (15 m) :Our system offers a streamlined solution for integrating thermocouple inputs from the heated part to the power source. A robust cable eliminates the need for individual wire stringing, reducing clutter. The terminal connection allows for the use of up to six thermocouples with ease and efficiency.
Switch Remote	Switch Remote Control the heating process remotely using our wired rocker switch remote, allowing for easy start and stop functionality. The remote comes equipped with a 7-meter cable for added flexibility and convenience.
