Sound Level Metering

Our OptiSLM sound level metering (SLM) systems bring advanced, innovative monitoring capabilities to MRI facilities and other settings where conventional SLM instruments are not suitable. OptiSLM brings excellent, real-time measurement capabilities for environmental monitoring, enabling dynamic microphone calibrations before and during MRI sessions. We offer two OptiSLM models:  OptiSLM 100A (for mounting inside ear defender)  OptiSLM 100B (for installation in MRI scanner room)

OptiSLM Features  Compact, self-contained, passive measuring device, compatible for use    with Optimic™ microphones  Enables environmental measurements for standard A and C weightings at    up to 140 dB  Complete EMI/RFI immunity means no effect on MR imaging  Operates over distances of 100 meters and greater  Option available for operation at high temperatures
