Note: It is strictly forbidden to twist and the ground is towed during construction. The tube head sheath is only allowed to be disassembled when the joint is installed;

●Sampling system: It can combine various types and materials of sampling tubes: Teflon PFA, FEP, PE, nylon 610, 12, copper tube, 316SS, 304SS, etc.

● Thermal system: high-efficiency insulation, flame retardant and lightweight insulation; automatic temperature-controlled self-regulating electric heating or parallel constant power heating.

●Electrical system: It can be equipped with instrument signal cable, compensation cable and control cable to meet the instrument display monitoring.

●Safety system: adapt to different process conditions, shield each system with aluminum foil or wire mesh to achieve fire safety, anti-static, electromagnetic shielding, and some waterproof membrane and reinforced flame retardant, UV-resistant jacket. The combination of multiple systems combines versatility into one, making the complex project simple and simple. It provides a good guarantee for remote work and remote diagnosis of the system. The heat tracing system keeps the gas in the pipe from condensing and keeps the measurement above the dew point, so the measurement accuracy can be guaranteed, creating conditions for centralized centralized computerization; the outer sheath can be strengthened to prevent crossover or damage due to other factors.
