Personal aerosol monitor and datalogger

September 2013 Analytical Instrumentation & Environmental Monitoring

The Thermo Scientific personal DataRAM pDR-1000AN monitor is a passive sampling light-scattering nephelometer that measures real-time mass concentrations of dust, smoke, mists and fumes in industrial environments.

* Measures airborne particulate concentration in real-time.

* Simple zeroing and calibration.

* No moving parts, silent operation.

* Compact, durable and self contained.

Nephelometry, a light scattering technology, is highly sensitive and incorporates a pulsed, high output, near-infrared light emitting diode source, as well as a silicon detector/hybrid preamplifier, collimating optics and a source reference feedback PIN silicon detector .

An optical feedback and stabilised sensing system, sets the standard for sensitivity, long-term stability and reliability. Simple zeroing, with particle-free air, is quick using the included zeroing kit. The internal firmware controls an automatic calibration check. A gravimetric calibration can be performed by weighing a separate filter sample and programming the calibration constant to provide the same reading.

The Pdr-1000AN monitor is an ultra-compact, durable and self-contained instrument designed for hand-held or belt-worn unattended operation. There are no moving parts which provides for silent, dependable operation.

Selectable alarm levels with built-in audible signal and switched output, an RS-232 communications port and a programmable analogue concentration output are all included in this versatile instrument.
