SHARE

The IN102 introduces a cyclone inlet to allow for sampling particles in a specific size range. We carefully monitor and adjust the instrument flow rate. In combination with the cyclone inlet, this allows us to measure particles separately at PM2.5 and PM10, the sizes most critical for air quality studies. This capability significantly enhances our precision and effectiveness in environmental monitoring and research applications.

Like the IN101 model it is small and compact and is enclosed in an environmentally protected case, ready for outdoor deployment in rugged conditions. Power requirements are 40W @ 120 VAC (60W Max) and input power options include: 110/240 VAC,50/60Hz with provided power supply, and regulated 12VDC from sampling station with provided power connector. Other powering options can be made available upon request such as operating from batteries or solar power. Optional heaters are available at the expense of additional power consumption.

It is designed for robust operation under a wide range of conditions. While its rugged design allows for field deployment, it is also a highly sensitive instrument which can be used in the laboratory or modified for use in aircraft. In this regard, the IN101T is highly versatile and can work in different environments and for different purposes.

The IN101T is recommended to use for measurements of all particle sizes at normal ambient conditions as well as for situations where higher pressure intake is required – i.e. high altitudes, clean condition or longinlettubes.
