The DataRAM 4 is a high-sensitivity, two-wavelength nephelometric monitor with a light scattering sensing configuration that has been optimized for the measurement of the fine particle fraction of airborne dust, smoke, fumes, and mists in ambient, atmospheric, industrial, research, and indoor environments. The DataRAM 4 provides direct and continuous readout as well as electronic recording of the information gathered.
Key Features:- Compact, rugged, and totally self-contained
- Designed for portable operation, as well as unattended fixed-point operation
- Powered by internal rechargeable battery or by an AC power supply/charger (included)
- Instrument automatically checks its own optical background during the zeroing sequence and indicates any significant deviations requiring maintenance
- Covers a wide measurement range from 0.0001mg/m3 (0.1µg/m3) to 400mg/m3, a four million-fold span ranging from very clean air to air with extremely high particle concentrations
- Complete, large-capacity (50,000 data point) internal datalogging capabilities with data retrieval on screen or through an externally connected computer
- Stored information includes individual point averages, particle size, temperature and humidity with time information as well as overall average and maximum concentration and tag numbers
- Selectable alarm levels with built-in audible signal as well as switched and signal outputs, RS-232 and RS-485 communications ports, and a programmable analog (voltage and current) concentration output
In addition to autoranging real-time readout, instrument also offers wide range of information via four-line scrolling LCD screen:- Median particle diameter
- Scattering coefficient
- Angstrom coefficient
- Visual range
- Run start time and date
- Time averaged concentration
- Elapsed run time
- Maximum with time of occurence
- Air temperature and relative humidity
- Operating parameters and diagnostic information
