Quick and easy dust measurement
531 has the advantage of instantaneous visibility of dust concentrations and trends, which can be used for on-site sampling and real-time measurements. 531 monitor interface is simple, very easy to use. The user can take measurements within a few seconds after starting the instrument.
On-site calibration of the instrument’s accuracy can be done using the calibration plug. This is the characteristics of this product, other companies currently do not have this feature of the instrument. The screen is color-coded for ease of use, green at the start of measurement (shown below), red at stop. During the measurement, the real-time values ​​and average values ​​of the real-time dust are displayed, and then the data is stored in memory for later viewing.
