DMS500 Key Features
Measurement of the aerosol size spectrum from 5nm to 2.5μm for both solid particles and liquid droplets
The fastest time response available: 10 Hz data, 200ms T10-90% response
High sensitivity - suitable for ambient measurements
Integrated two stage dilution for high concentration measurements, including combustion exhaust
Electrical Mobility Measurements
The DMS500 combines electrical mobility classification of particles with sensitive electrometer detectors, allowing generation of particle size / number distributions in real-time.
These outputs may be further processed to give simultaneous outputs of particle size, number and mass.
With flexible sample handling options the DMS500 is ideally matched to a range of applications from ambient and process monitoring to direct measurements of high concentration sources such as combustion.
Fast Time Response for changing aerosols
Patented features of the DMS500 give it a T10-90% response of just 200ms; the fastest time response available in any ultrafine aerosol sizer.
This fast time response is especially applicable in resolving of fast changing phemomena, with applications including combustion emissions, drug delivery systems, tobacco smoke research, pyrotechnics and indoor air pollution.
Low Diffusion Losses
The DMS500 uses a high sample flow rate (8 litres per minute) and unique multiple sheath flows in the charger, resulting in low diffusion losses even of small particles smaller than 10nm.
No Radioactive Charger
The DMS500 uses a controlled corona charger - no radioactive sources are required. This makes the DMS500 easily transported to different laboratory, industrial or even domestic settings for measurements.
Each DMS500 undergoes a traceable calibration procedure, involving real aerosols, taking full account of particle losses, and even different particle morphologies thus preventing the drop in accuracy at larger sizes seen in some other analyzers.
An optional portable size check kit allows the user to check the sizing accuracy of the DMS500 on site, without the need for any other equipment.

User Interface Software
The user interface includes full datalogging of measurements and operating parameters, and runs on a Windows PC. The software is supplied as standard with a multi user licence- no need to dedicate a particular PC.
The DMS500 is easily to integrate with other test equipment- four analogue inputs are recorded to the data file, and four analogue outputs may be configured in software. The instrument can be controlled via digital remote control and can even trigger other equipment at a preset aerosol concentration (for example a roadside camera). Data presentation tools for MS Excel are included to assist in understanding the data from the DMS500.
Sample handling & conditioning options
The DMS500 may be ordered with an integrated two-stage diluter and heated sample line, allowing measurements from engine exhausts with no additional equipment.
To facilitate unattended operation in applications such as ambient monitoring, the DMS500 supports scheduled operation based either on fixed time intervals, or a more sophisticated schedule text file.
