HD-7204 Personal Direct Reading Aerosol Monitor
The all new Haz-Dust™ HD-7204 offers a flow compensated pump for compliance monitoring. The days of requiring two devices and co-locating a FRM filter cassette and real-time reading instrument are over! The HD-7204 offers a flow compensated pump with real-time capability. The sensor, which is mounted in the OSHA defined breathing zone, is sandwiched between the sampling inlet and a FRM filter cassette option.
