SM-7204 Personal Silica Monitor
SM-7204 Personal Silica Monitor Overview
SM-7204 Monitor Kit includes monitor, 37-mm 2-piece opaque filter cassette, open-faced sampling adapter, thoracic sampling inlet, IOM inhalable sampling head, flow adapter, zero accessory, battery charger, and DustComm Pro Software
Requires calibration with equipment sold separately
The Environmental Devices Corporation SM-7204 provides immediate identification of problem areas and tasks. Quickly implement controls to reduce exposures to hazardous particulate and then measure the effectiveness of controls moving forward. There’s no further need for two co-located devices – one SM-7204 with built-in compensating pump and preweighed filter cassette simultaneously provides real-time particulate readout and gravimetric sampling. The SM-7204 alerts users of approaching thresholds for immediate corrective action. Designed carefully with you in mind, the SM-7204 provides cost-savings and the widest range, lowest detection, and best resolution of any personal dust monitor on the market.
