Chinese Professional Programmable Light Fastness Tester Equipment - HAST accelerated aging test chamber – Hongjin

 First, structure and materiala. Round inner box, stainless steel round test inner box structure, in line with industrial safety container stadards, can prevent dew condensation in test
meter.
b. Round lining, stainless steel circular lining design, can avoid the direct impact of vapor latent heat on the sample.
c. Precision design, good air tightness, low water consumption, and can be continuously operated for 400Hrs every time.
d. Patented packing design makes the door and the box more tightly integrated, which is completely different from the traditional extrusion type, which can extend the packing life. e. Critical point LIMIT mode automatic safety protection, abnormal cause and fault indicator display

Temperature electrothermal circulation system:
1. Heating system spinning: heat-dissipating ring electric heater;
2. Heating tube: It adopts all-stainless steel seamless casing, the insulation resistance is greater than 50MΩ, and it has anti-dry control;
3. Control mode: Balanced temperature control system (BTHC), P.I.D. control SSR solid state relay realizes high-precision non-contact switch control, so that the heating amount of the system is equal to the heat loss, so it can be used stably for a long time.
