Three Zone Hydrogen Gas Tube Furnace with Hydrogen Detector for Processing Material up to 1200°C Safely

Product Name: Three Zone Hydrogen Gas Tube Furnace with Hydrogen Detector for Processing Material up to 1200°C Safely

Product Model: OTF-1200X-III-H2

Product Description: OTF-1200X-III-H2 is a safe hydrogen tube furnace. The processing tube is made of high-quality Ni-based superalloy which never cracks and is broken at flowing Hydrogen gas. Two hydrogen detectors are included which will shut down the Hydrogen gas generator and gas inlet valve immediately once detecting hydrogen gas leaking. The tube furnace is designed for processing material under hydrogen gas up to 1200°C safely. The precision temperature controller is 30 segment programmable.
