SALD-3101 is useful wherever there is a need to measure coarse or dense particles, including the fields of metals, minerals, pharmaceuticals, chemicals, environment, river conservation, disaster prevention, civil engineering, construction, agriculture, and soil.

Seamlessly covers an extremely wide range of particle diameters from 0.05 to 3000µ using a single measurement principle, a single optical system, and a single light source. Always achieves accurate particle size distribution measurements across the entire measuring range using a single standard, without data discontinuities from a multiple optical system combination.

The sampler incorporates a powerful vertical radial pump with a flow rate of 5000 cm3/minute to reliably circulate coarse or dense particles from several hundred microns to several millimeters in size. This powerful particle circulation is the key technology behind the 3000µ (3mm) upper measuring limit.

Select from an extensive range of options to suit the sample type and the aim of the measurements.

Dry Measurement Units
These units measure the particle size distribution of a sample powder dispersed in the air.
Use these units for particle size distribution measurements of powders with no suitable dispersion medium and powders that dissolve in liquids.
Two unit types are available, to suit the sample state and measurement aim.

SALD-DS21 Injection type Dry Measurement Unit (measuring range: approx. 0.8 to 1000um) (P/N 347-60100-20)
Sample powder is dispersed for measurement by injecting in the air from a nozzle.
The unit offers three types of sample suction mechanism and three types of nozzle, which allow setting of the optimal dispersion force and sample volume conditions to match the sample state and aim of measurement.

SALD-DS3 Free-fall type Dry Measurement Unit (measuring range: approx. 10 to 3000um) (P/N 346-61206-10)
The sample is measured during free fall.
Even easily damaged particles can be directly measured,
A separate dry-measurement detector case (P/N 347-60010-20)
compressor (SALD-DS21 only) and dust collector are required to use the dry measurement units.

SALD-AC30 Acyclic Motion Sampler (P/N 346-83746-02)
Completes one measurement cycle in 30 seconds, Including washing. Automatically detects sample infuse to start measurement and data storage. The rapid measurement time saves effort and makes this the optimal unit for measuring samples with a rapidly changing particle size distribution, such as powder undergoing a grinding process.
