Available for hire

Hover to zoom

The TSI Quest Edge 4 and Edge 5 instruments are lightweight, at 85 grams, dosimeters that feature a thin, contoured shoulder mount. With the Edge 4 you can monitor and log noise studies by enabling two different parameter settings in one dosimeter, also refered to as "virtual dosimeters".  For instance you may want to set one dosimeter to log against IEC standards and also monitor noise with the OSHA settings.  The Edge 5 in addition to being intrinsically safe also allows you to monitor and log via the DMS software a third noise study.
