When a shielded room is necessary?
· If your lab is near a broad spectrum emitter (i.e equipment that transmits multiple frequencies under 400Hz), radio tower, mobile phone transmitter or other large field generators, then you should consider a shielded room.
· If your research is in the gamma band and you do not want to use a 60/50Hz notch filter to remove mains power noise, you might consider a shielded room. We recommend taking the steps above to first minimize the mains power noise. If that is not sufficient for your needs, then a shielded room may help.
Product Features | ||||
Shielding panels are made of molded cold-rolled steel plates. They are jointed in way and welded with CO2 protection, which can restrain the plates from distortion and ensure the leveling of the steel plates. | ||||
Self-supported frame construction is made of section materials. | ||||
Shielding door is optional: standard electromotive door (electromotive / manual alternative), full-automatic shielding door (light-activated with password) sliding door. Subshining stainless steel decoration is on surface of the door. Standard dimension of the door is:0.85×2(m). | ||||
Large-scale hanging sliding shielding-door, electromotive sliding push-in door, electromotive sliding gasbag door, rotated door with track. | ||||
Ventilated window is designed in cellular wave-guide type with dimension:300×300(mm). | ||||
Power filter is in condition of high-performance and low-leakage. | ||||
Telephone, air-conditioning, fire-fight devices, optical fiber and CAT5 cables can be equipped customized. | ||||
Decoration will be arranged in the shielding room according to standard equipment room requirements. | ||||
