LPA-3000S Split Spray Particle Analyzer 0.1µm - 3000µm Laser Particle Size

Product Specification

LPA-3000S split spray laser particle size analyzer, 0.1µm～3000µm 

Product Introduction

The LPA-3000S spray laser particle size analyzer (split type) uses the full-scale Mie scattering theory and Shuoboda's proprietary technology to calculate the particle size distribution of the measured particles. The stainless steel chassis is fully sealed, dustproof and waterproof, and has good electromagnetic shielding and anti-interference performance.

The interval position between the main machine and the auxiliary machine can be freely adjusted according to the size of the sample to be measured, and the maximum distance can reach 10 meters. The built-in camera automatic centering system is convenient for calibrating the light source on the test site. The automatic continuous test can be turned on under computer control to quickly analyze the particle size distribution data of the measured water mist, oil mist, smoke, etc. The unique precision mechanical structure makes the test fast, repeatable and stable. Through the particle size distribution data of the droplet measurement, the nozzle design and spray conditions are optimized, the spray effect is evaluated, and the purpose of research and development and product quality control is achieved.

Application field

It is widely used in pesticide spraying, medical atomization, fuel spraying, fire water mist, various atomizer production, research on combustion efficiency products such as aircraft engines, as well as various fields such as scientific research institutions.

Performance characteristics

1. Split structure: It is installed between the main machine and the auxiliary machine according to the measured component (provided by the user). The distance between the main machine and the auxiliary machine is not limited, which is convenient for testing large and small products. Under computer control, the device automatically turns on and off the measured product to automatically complete the test.

2. It adopts Fourier optical system, large diameter parallel light source, large test section, and strong data representativeness.

Large aperture lens, wide signal acquisition angle, fully collects the scattered signal of the spray, and ensures that the nozzle is used as far as possible, usually within the range of 100-3000mm.

3. 128-level multi-element detector. There are many particle size grades, small level difference, and high resolution of scattered signal detection. Each level of the detector background light is independently compensated to achieve gain, high-speed acquisition signal amplification, and sensitive and fast dynamic response. There is a complete spot image detection system behind the detector to obtain a real spot. Comprehensive monitoring of spot uniformity and shape.

4. Imported semiconductor laser, light source: wavelength 650nm, 30mw, life> 70000h. .

5. High rigidity optical structure, stable optical path, no adjustment is required during use. Ensure long-term stability of the instrument, good test accuracy and repeatability.

5. Due to the large difference in spray particle size and spray diameter, the laser power can be adjusted in the full range to ensure the resolution and accuracy of the instrument.

Multifunctional operating software

1. RS232 and USB data transmission methods are adopted, and the transmission distance can reach 100 meters.

2. The test data include: cumulative distribution, frequency distribution, cumulative 10%, 50%, 90%, 97%, average particle size and specific surface area, etc., which fully characterize the particle size characteristics of the sample. Each test takes a few seconds, and can be tested automatically one time or multiple times continuously.

3. The software operation interface can be selected in Chinese or English, and the output results can be printed directly, or converted to PDF and saved in format.

4. In order to meet the needs of different users, it is equipped with program trigger, TTL level and switch trigger high-speed test, and 50 complete test data are automatically recorded and saved per second, as a basis for research such as dynamic spray. . The analysis software is compatible with Windows XP/Win7/Win10 systems.
