HAZ-DUST 7204 Particulate Monitor
Personal real-time aerosol monitor, capable of measuring a wide variety of harmful particles and aerosols.
HAZ-DUST 7204 Particulate Monitor Overview
The SKC HAZ-DUST 7204, superseding the SKC SM-4000 Personal Silica Monitor, provides comprehensive, personal, real-time aerosol compliance monitoring for a wide range of harmful airborne particles.
The SKC HD-7204 is intended to allow Occupational Hygienists and safety professionals to immediately identify areas and tasks which carry a high risk of exposure to lung damaging particles and aerosols. When used as part of a routine air-monitoring program, the HD-7204 Particulate Monitor reduces the number of filter gravimetric tests and laboratory analysis required by returning accurate particulate concentrations in real-time. Immediate results reduce testing costs and ensure that workers can be alerted straight away if they are in danger so that corrective action can be taken.
The SKC HD-7204 aims to make particulate monitoring simple and accessible without sacrificing comprehensiveness or accuracy. The instrument eliminates the need to use both an FRM filter cassette and a real-time reading instrument. By offering a flow compensated pump, compatibility with all pre-weighed filter cassettes and with real-time measurements, the HD-7204 can be used in a wide variety of industries including those at risk of silica exposure, pharmaceuticals and construction dust.
A comprehensive personal particulate monitor, the HD-7204 Monitor protects workers through the breathing zone mounted sensor which is located next to either a 25 or 37mm filter cassette and the interchangeable sampling inlets for respirable, inhalable and thoracic particulate size fractions.
The graphical touch-screen display informs the wearer of real-time particulate concentration through time vs concentration graphs and an early warning alarm system when exposure thresholds are at risk of being exceeded.
Protect workers and ensure compliance with the SKC HAZ-DUST 7204 for real time, comprehensive personal aerosol and particulate monitoring.
