For Compressed Air, Nitrogen N2, Carbon dioxide CO2

The S600 Portable Compressed Air Purity Analyzer provides an all-in-one solution to measure dew point, particle and oil vapor as specified in the ISO 8573-1 standards. It combines the latest sensor technology, software-guided measurements and a time-saving setup into one portable, touchscreen controlled multi-tool. With our S600, compressed air quality measurement audits can be finished in minimal time compared to traditional methods.

Compressed Air Quality Measurements According to ISO 8573-1

Many industries like the pharmaceutical and food industry require high-quality compressed air. Process and product safety can be ensured by frequent measuring of compressed air quality, while meeting the ISO 8573-1 standard requirements. At the same time, monitoring the compressed air quality can avoid production downtime and improve system reliability.

On-Site Measurements for Great Flexibility

Forget the old methods of compressed air quality and purity monitoring. The S600 monitoring solution uses software-driven measurements to ensure a peak level of flexibility and accuracy. With a vibrant 5-inch touch screen, you can control and monitor all the data directly at the measurement location. You get the whole package in one easy to carry case. This can be taken with you anywhere with ease. The S600 case is 45 x 38,1 x 19,05 cm in size.

5 in 1 Measuring Device

The S600 Portable Compressed Air Purity Analyzer measures dew point/humidity, particle counts, temperature, pressure, and oil vapor with high accuracy in one device. With an integrated data logger, the data recording of these parameters for further data analysis has never been easier.

  • Particle measurement from 0.1 < d ≤ 0.5 µm, 0.5 < d ≤ 1.0 µm, 1.0 < d ≤ 5.0 µm is possible, thanks to the latest laser detection technology. The measurement methods meet the requirements of the ISO 8573-4 standards (together with the isokinetic sampling device). Counting efficiency according to ISO 21501-4 30…70% of d> 0.1 µm, 90… 110% od d>= 0.3µm.
  • Oil vapor measurement from 0,001 bis 5,000 mg/m³ is provided by state-of-the-art photoionization detector (PID) with self-calibration. The measuring range is measured according to ISO 8573-1 Class 1 to Class 5, with high precision (5 % of reading ± 0.003 mg/m3 accuracy).
  • Pressure Measurement with the latest sensor technology, providing important additional quality data about the compressed air system.
  • The Integrated data logger records all channels in parallel for later analysis. The 5’’ touchscreen allows you to interact with the device on site. There is no need for a PC to manage the device.
ISO 8573-4 Isokinetic Sampling Device

For particle measurements according to ISO 8573 an isokinetic sampling tube has been designed. This optional equipment enables you to monitor and adjust the air flow of the particle measurement to ensure the correct isokinetic sampling.

Create Powerful Reports for Compressed Air Audits

The S600 enables users to create powerful PDF reports directly on site. The reports are following the recommendations stated in the ISO 8573. Customer related data as well as service provider details can be entered on-screen, making it even easier to perform audits and to create meaningful reports. PDF reports can be created from any recordings on the device and are copied on the fly to a connected USB drive for direct print-outs.

Optional 4G/LTE Remote Connection

By integrating a USB port for 4G dongle connection outside the S600 casing, the portable devices can be easily connected to the S4A Software and monitored remotely. This eliminates the need of a WiFi connection. The USB 4G dongle is an optional feature and can be ordered together with S600, but also upgrade later. To use the new feature, a SIM card is required.
