The temperature and humidity performance test is based on the relevant regulations of the IEC60068-3 standard; the sensor is placed at the unit outlet.
Overall structure and chamber was composed of three parts as below.
Insulation box, separate refrigeration units, and electrical control cabinet.
1.Chamber size Inside size: W 700 × H 700 × D 480 mm
Exterior size:Approximately W 900 × H 1735 × D 1500 mm
2.Insulation box ※ wall material: high-quality carbon steel with static color spray
inner wall material: SUS304 # matte stainless steel plate
Insulation materials: rigid polyurethane foam insulation layer + glass fiber.
3.Door Single door, left open,Heating wire was installed at the door frames to prevent condensation at low temperatures.
Two explosion-protected chains are added on both sides of the box door. The chain is longer. When the box is opened, it can be opened a bit, letting Quick release of internal air pressure, but no pop.
4.Observation window With 1 set 210 × 270mm (width × height) observation window,Glass enclosed
stainless steel protective net, to prevent the explosion when flying glass (can not guarantee absolute
5.Lighting device LED Lighting devic *1 located on observation window.
6.Heating Quality nickel-chromium alloy wire electric heaters,
Non-contact control mode (SRR).
7.Humidifying Steam heating and humidification method;
Stainless steel sheathed heater;
Heater control: contactless control (SSR);
Water level control device, heater anti-dry device.
8.Water outlet hole Equipped with studio condensate and unit condensate drain holes.
9.Cable hole Φ100mm*2 located on both sides (each*1) with rubber stopper and plastic cover
10.Sample holder Two layers of stainless steel sample holder,Height adjustable,every holder could load 30KG.
11.Mobile Casters Mobile Casters *4 with foot cups.
control box Total power circuit breaker, over-temperature protection.
supply system Water pump automatic supply.
14. Explosive pressure
Release device When the pressure in the equipment or pipeline exceeds the pressure of the safety valve, it will automatically open and relieve pressure
Equipped with: sensor switch, exhaust fan
a. When the test article in the box is exploded, there can be a pressure release pipe.
b. Protect test equipment from damage caused by sudden pressure changes.
c. Protection personnel.
