  • Qt 1 Laser Particle Size Analyzer - China

    price: contact company for price

    Principle of operation The QT-1 laser particle size analyzer uses Mie scattering theory to measure particle size, considering the refractive index of the particles and dispersion medium.

    According to Mie’s theory, a particle will scatter light at an angle determined by that particle’s size.

    A collection of particles will produce a pattern of scattered light defined by intensity and angle that can be transformed into a particle size distribution result.

    The data of particle test can be calculated in two ways: unconstrained fitting inversion and constrained fitting inversion.

    The constrained fitting inversion is a relatively simple way.

    QT-1 Laser Particle Size Analyzer Specifications Measurement range:0.05 ~ 800 µm

    Accuracy:<±1% (Chinese National Standard D50)

    Repeatability error:<±1 % (Chinese National Standard D50)

    Power supply:220±10V AC, 50Hz, 200W

    Dimensions:1000 x 330 x 320 mm

    Weight:38 KG Technical features Stable performance: The stability of the tested data is ensured by the stable optical signals from the system.

    The QT-1 Laser particle size analyzer uses He-Ne gas laser light source with 0.6328 micron wavelength.

    It can offer stable laser source signals, and serves more than 15000 hours.

    Mixing system: choose the appropriate mixing speed according to the characteristics of the sample, to prevent particle sedimentation to dispersion mixing, stirring speed is in automatic operation and touch-button is continuously adjustable at the stirring speed from 0 to 3000 r/minutes, speed setting is displayed, open the ultrasonic system during testing process can avoid measurement errors caused by bubbles emerging from fast stirring.

    Circulatory system: According to the characteristics of the sample, choose appropriate in circulation pump speed to prevent particle precipitation in the circulation line.

    Circulation pump speed is in automatic operation, touch-button is continuously adjustable at the circulation pump speed from 0 to 5000 r/min, pump speed setting is displayed, open the ultrasonic system during testing process can avoid measurement errors caused by bubbles emerging from fast stirring and can prevent particles from becoming aggregates.

    Powerful analysis software: PADMAS (Particle Diameter Measure & Analysis System) is a powerful software that can process statistical analysis, comparison and mode conversion.

    It has various formats, such as differential distribution, cumulative distribution, standard classification, R-R distribution, user-defined classification, mesh-based classification and quantitative distribution.

    The default in the range of 0.02 -2000 micron is 130 classes.

    Within the measurement range, 1-130 classes can be defined by users.

    In the test report, there are particle size distribution chart, particle size data, and some characteristic parameters such as D10, D50, D90, the average size and specific surface.

    Four parameters need to be defined by users.

    Weight specific area and volume specific area can be mutually converted.

    Particle size data can be exported to Excel.

    It supports test report printing in Chinese or English.

    The page header and footer may be modified.

    The printing page may be previewed.

    Particle distribution diagrams and size data charts may be saved in picture or PDF format, which can be further used in Word.

    More functions may be added according to users’ requirement.

    User-friendly operation: The operation is standard, quantified and simple, and it takes a short time to master the operation.

    The data can be tested within 1 minute.

    High viewability: The test software is user-friendly.

    The test processes are readable and instantly refreshable.

    The operators can observe the instrument’s situation and the fluctuation of the test data at any time and analyze the validity and reliability of the test data.

    On the intelligent touch panel, there are operating keys for circulation, ultrasonic, stirring and discharge.

    Standard, quantified and simple operation makes the testing time shorter and lower requirement for the operator.
