We are the only official distributor in Thailand.
The Robot Sifter RPS-01 is a sieving particle size distribution analyzer that automates everything from sample input to sieving, weighing, and calculations.
It uses an ultrasonic sieving principle, which reduces friction between the sample and the sieve mesh, allowing for sieving without destroying particles compared to vibration or low-tap sieving methods. Measurement results are displayed on the operation panel and can be output to various printers.
The RPS series is a long-selling product with a proven track record, so we hope you will adopt it and use it to streamline your process management, quality inspection, and more.

Features
Automatic Measurement | The measurement is fully automated, from measuring the sample weight, sieving, calculations, to printing out the data. The operator simply sets the sample and presses the start button to complete the measurement. |
More efficient screening | The effect of mechanical pulses is that the sieve mesh is less likely to clog than with low tap or electric vibrating screens, and sieving time can be reduced. |
Low noise | It is quieter than low-tap and electric vibrating sieves. |
Measurements can be performed without destroying the sample | The sample vibrates vertically during measurement, reducing friction between the sample and the sieve mesh, preventing sample destruction and slowing mesh wear. |
Suppresses static electricity and prevents sample aggregation | By changing the frequency of the sound waves and adjusting the rise and fall times of the sound waves, it is possible to control the sample so that it does not become charged. |
Prevent data tampering | Users can be assigned to each person in charge, and operation logs for each user are recorded on the device itself. Also, to prevent measurement data from being tampered with, the device does not have a function for editing data from the device itself. The data management PC software can also be optionally changed to DI-compatible software. |
Free power supply | The input voltage to the device is compatible with AC100 to 240V. |
