Custom resisters
In consultation with hans rudolph inc., customized resisters can be provided according to customer specifications. Technical support because the flow range of each r value is limited
Designation (cmh2o/l/s, hpa/l/s)。
Custom resisters for the mri environment, made entirely from non-ferrous metal materials, may be requested。
Attention
Attention
1. Do not attempt to clean, disinfect or sterilize. This will render warranty and calibration ineffective。
2. Do not attempt dismantling. This will render warranty and calibration ineffective。
3. These resistors do not apply to respirators or other equipment
4. These resistors do not apply to any wet-gas flow circuits because the hydroccumulation in the resistance element affects calibration performance。
• these resistors do not apply to any type of respiratory circuit because there are no proven methods of cleaning, disinfection or sterilization, the result of which may cause biological harm to patients, clinicians and researchers。
• these resistors do not apply to any wetter patient or other air flow circuits, as the accumulation of moisture in the resistance element affects calibration performance。
• linear electrical resisters do not apply to the calibration standards for humans or as medical equipment。
