The Aerosol Particle Size Spectrometer LAP 322 provides the determination of aerosol particle size distributions (0.2-40µm) and particle concentrations. It is based on optical single-particle measurements by means of 90° scattered light measurement.
The particle counter LAP 340 is a mobile useable evaluation system for measuring the number and size of particles in air streams and gaseous media.
The measuring range comprises 0.3 … 10 μm in 16 particle size channels at a flow rate of 28.3 l/min.
This makes it suitable for a variety of measuring tasks. These include monitoring and checking of clean rooms, clean benches, filter facilities in operation rooms or filling facilities in the pharmaceutical industry.
Solid-particle aerosols are used for research, development and quality management in numerous fields. They are produced by dust generators. In case dry and easy flowing substances are applied, the dust generators of the model series SAG 410 are suitable. They transport the solid material using a dosing belt (VDI 3491-8).
The SAG 440 ASHRAE dust disperser has been especially developed to meet the requirements as defined by the ASHRAE 52.2 and DIN EN 779
standards for testing the performance of particulate air filters. Due to the particular physical properties of ASHRAE test dust it was necessary to adapt the instrument to this material.
The SAG 440 is particularly suited for dosing dusts containing a certain proportion of fibres and provides excellent results when producing test
dust to check separation efficiencies.
The products of the ATM series are used to generate test aerosols with defined properties (VDI 3491). The technological and design solutions
of the ATM ensure a high consistency of particle size distribution and particle concentration. The generated aerosol is highly reproducible.
The ATM 220 is powered by compressed air and is therefore particularly suitable for use in the lab or on the filter test stand.
The Atomizer Aerosol Generator ATM 226 is especially suited for clean room and filter testing applications according to international standards.
Function test at laminar flow boxes (DIN EN 12469) and cytostatica safety workbenches (DIN 12980), the qualitative test of filters for suspended matter (HEPA and ULPA filters), and acceptance measurements in clean rooms (according to DIN ISO 14644 and VDI 2083) are a essential necessity for personal security and product safety.
The aerosol generator ATM 228 is a further development of the aerosol generator ATM 226 and serves for the mobile generation of test and calibration aerosols from pure liquids, solutions and suspensions. The generator complies to all requirements of VDI 3491-2.
Aerosol generation is realised by a brushless com-pressor. Accordingly, no external compressed air supply is required. For the purpose of reproducible and long-term stable aerosol generation, the air flow rate is controlled via the pressure drop over the nozzle. This allows also a reproducible and stable generator operation even at very low air flow rates and thus also at lowest particle production rates.

DIL 550 - Dilution System for Aerosols
The Aerosol Dilution System DIL 550 is designed to accurately dilute aerosols to produce a defined particle concentration for certain measuring tasks. The main application of the dilution system DIL550 is the verification of test aerosols for testing clean rooms. DIN EN ISO 14644-3 defines the necessity of appropriate dilution systems when using test aerosols for verification.In the applied principle that corresponds to the standard VDI 3491-15, particles are removed from the sample aerosol according to the specified dilution ratio. The particle size distribution remains unchanged.
The DIL 554 has a stainless steel casing with integrated battery operation (AC adapter optional).
It was especially developed for validation and monitoring of clean room facilities.
Benefits
- designed for mobile use (no auxiliary pressurized air and additional exhaust needed)
- battery-operated with status indicator (optional with power adapter)
- constant and reproducible aerosol dilution even under changing operation conditions
- continuous control and display of actual dilution ratio
- long-term lifetime and reliability, minimum maintenance required
- precise operation in both over and under pressure mode
This device dilutes aerosols for total volume flows ranging from 0.5 l/min to 3 l/min, the dilution factor being
adjustable. Both of these values, the measured total volume flow and the dilution ratio are displayed to the user via the LCD display of the device. The device is easy to operate, ensures an
exact dilution of the aerosol and features flexible use due to its design.
Special Advantages
- Flexible total volume flow range
- Adjustability of the dilution factor
- Simultaneous monitoring of the total volume flow from the particle counter
- Continuous monitoring of the dilution ratio
- No auxiliary or exhaust air necessary
- Minimal maintenance
The DDS 560/C is an aerosol conditioning system
that serves for free-adjustable and defined
reduction of the particle number concentrations.
Moreover, the dilution system can be passively
operated by various aerosol sample flow rates.
Features
- free adjustable dilution factor over wide range (approx. one decade)
- compatible with various aerosol-analytical instruments (i.e., variable flow rate)
- automatic readjustment of setting value of dilution
- stand-alone or remote-controlled operation with parameter monitoring
