Model HD-1004
Hãng sản xuất: Environmental Devices Corporation - Mỹ
Applications
- Determining levels of worker respiratory protections for OSHA compliance.
- Compliance program reviews.
- Evaluating work practices and controls of any dust generating practice.
- Can be combined with NIOSH video exposure monitoring for real-time graphical overlays.
- Welding fume exposures.
- Air quality studies in occupational health and industrial hygiene.
- Haz-Mat air quality investigation and waste site remediation.
- The Haz-Dust IV Monitor is a useful tool for all air monitoring applications involving lung-damaging particulates.
When used as part of a routine air-monitoring program HD-1004 can significantly reduce the number of filter gravimetric tests and laboratory analysis. For example: OSHA compliance air monitoring program may dictate air monitoring for particulates on a monthly basis to determine that work practices are below Federal Regulations. If a company has 10 or more employees at risk of exposure this can result in as many as 10 to 20 tests per month and subsequent lab analysis. By implementing a HD-1004 real-time dust monitor, particulate concentrations can be determined immediately and in real-time. No special skills are needed and no laboratory analysis is required. HD-1004 actually pays for itself by reducing the number of filter gravimetric tests by 25% to 50%. HD-1004 alerts you in seconds and allows you to take immediate corrective action.
HD-1004 is a personal real-time dust monitor with an internal air sampling pump that is microprocessor controlled. This allows for large data storage and on screen statistical calculations. The detached sensor is miniaturized and easily attaches to the individual's lapel for true breathing zone measurements.
