For Compressed Air, Nitrogen N2, Carbon dioxide CO2

The S130 / S132 is a new generation laser particle counter optimized for applications in compressed air or compressed gases. With quality in mind and with the knowledge of customer needs, this instrument is designed for continuous operation 24 hours, 7 days a week. This helps to ensure the compressed air quality while helping to avoid particle contamination of processes and products.

Particle sizes from 0.1 < d ≤ 5.0 μm
  • S130 Eco-Version: 0.3 < d ≤ 5.0 μm
  • S132 Pro-Version: 0.1 < d ≤ 5.0 μm
Integrated Pressure Diffuser

Unlike its competition, the SUTO Laser Particle Counters come with integrated pressure diffusers to reduce the line pressure inside the instrument. This enables users to use the laser particle counters directly from the compressed air system, without installing pressure reducers and therefore being in compliance with the ISO 8573-4 standard.

Integrated Display

The integrated 5” touch screen display offers live readings for all channels, signal output settings as well as an integrated data logger. This allows storage of the measurement data on the device. Measurement values represent the particle counts per ft³, l or m³, or alternatively in μg/m³.

Air Quality Monitoring According ISO 8573-1

The ISO 8573-1 defines the compressed air purity classes for particulates in a compressed air system by providing the limit values for each channel. The S132 Laser Particle Counter measures the channels as defined by the ISO 8573-1:

  • 0.1 < d ≤ 0.5 μm
  • 0.5 < d ≤ 1.0 μm
  • 1.0 < d ≤ 5.0 μm

For these 3 channels, the limit values are defined and divided into classes. But furthermore, as stated in the ISO 8573 standard, the fourth channel must be measured as well, d > 5.0 μm. This channel value must be 0 for the classes 0 to 5, otherwise the classification falls into class 6 or worse, where a mass concentration is defined as limit values.

Connections for Data Analysis

The user-friendly signal outputs (Modbus/RTU (RS485), Alarm relay (NO, 40VDC, 0,2A) and USB) make it easy to connect the S130/S132 to SUTO Displays and Data Logger as well as third-party displays and control units.

SUTO Exchange Service

The exchange calibration service eliminates downtime and enables users to have a seamless record of their dew point measurements.
