BT‐645 Portable Dust Monitor

Applica ons: x� Public and Workplace Monitoring x� Industrial / Occupa onal Hygiene x� Indoor Air Quality Note: Not recommended for con nuous outdoor use.

Op cal Sensor A laser op cal sensor is used to detect and measure par culate concentra ons up to 100 milligrams per cubic meter. The con nuous flow op cal sensor is combined with purge air to ensure accurate measurements in adverse environments.

Rugged Design The op cal sensor, matched electronics and backlit display, are enclosed in a rugged metal enclosure to protect the instrument from normal daily use.

Data Storage

The internal datalogger will store over 5,000 samples. Sample history events can be viewed on the display or downloaded to a computer using Comet so ware.

Ba ery Opera on The internal ba ery pack provides over 10 hours of con nuous opera on. Ba ery recharge me is approximately 2.5 hours.

Op onal Inlets The standard unit is supplied with a TSP inlet. Op onal sampling inlets are available for PM2.5, PM4 and PM10.

Key Features: x� ‘Real Time’ monitoring x� Simple opera on x� Rugged design x� Built‐in Datalogger x� Purge air system x� Low power consump on

Thermo Scientifi c PersonalDataRAM pDR-1500 Monitor Active, real-time aerosol monitor/data logger with aerodynamic sizing

The Thermo Scientifi c™ pDR-1500 personal DataRAM was developed to meet the need for a fully integrated, active sampling personal scale instrument with greater accuracy, increased capabilities, low size and weight, maximum ease-of-use and increased operating time.

• True volumetric fl ow controlInterchangeable cyclones for higher

• Accuracy cut points Personal aerosol instrument with benchtop performance

• Full compensation for environmental variables

• Suitable for NIOSH Methods 0500and 0600

The pDR-1500 personal DataRAM is designed for applications such as site remediation, size discrimination, mass validation, exposure modeling, and protection of asthma patients.

The pDR-1500 personal DataRAM accurately measures aerosol concentration in real-time, with relative humidity compensation, true volumetric fl ow control and legacy pDR nephelometry. An integrated sample fi lter enables post-gravimetric validation of data.

Superior particle-cut points compared to those achievable using impactors are delivered through volumetric fl ow control and ACGIH traceable cyclones, available in pairs, for PM10 and PM4 or PM2.5 and PM1. A toroidal entrance assures optimized aerosol aspiration and a representative sample even without a cyclone.
