The SV 104 BIS is an intrinsically safe noise dosimeter with a robust half-inch patented MEMS microphone. Among its features are automatic noise dose calculation software, sound pressure level logging, audio recording, octave band frequency analysis and auto-calibration.

QuantiFit2 uses patented controlled negative pressure technology to perform quantitative respirator fit testing. The test uses only air and takes less than two minutes to complete. The instrument creates and maintains a negative pressure within the respirator facepiece and measures the exact amount of air that leaks in.

The OHD Quantifit uses scientifically proven and patented controlled negative pressure technology to directly measure respirator leakage.

Complete fit testing in two to three minutes with the Quantifit.
