Envirotect can offer a range of independent testing services.
RF Attenuation Test
Envirotect can perform RF attenuation tests on RF cages using highly sophisticated test equipment, consisting of a Signal Generator, Spectrum Analyser and a pair Di-pole Antennae. The procedure can also cover ground isolation testing of the cage. Results will be recorded accordingly and a test report will be issued.
EMI (Electromagnetic Interference) Test
Imaging diagnostic equipment such as MRI & CT Scanners are sensitive and can be disturbed by environmental electromagnetic interferences.
An EMI Test evaluates the level and source of electromagnetic interference generated by a number of sources including moving vehicles, trains, elevators, power lines, transformers which may affect the performance of the imaging diagnostic equipment.
The test involves placing a magnetometer at the exact position of the isocenter of the proposed MRI Scanner and measuring over a period of time the AC fluctuations and DC disturbances in X, Y & Z axis.
Information is recorded by the data acquisition unit and will indicate whether the proposed siting of the scanner is within the specification of the MRI/CT Scanner manufacturer.
Imaging diagnostic equipment is very sensitive to environmental vibration. Structural vibrations can be generated by a number of sources including motors, pumps, elevators and moving vehicles.
The survey is performed to measure steady state and transient vibration using a PCB Piezotronic Seismic Accelerometer positioned either at the proposed isocenter of the imaging diagnostic unit or a position dictated by the customer. The data acquired and recorded on the data acquisition unit over a period of time will indicate whether the proposed position of the imaging diagnostic unit is within the specification of the MRI/CT Scanner manufacturer.
