AirPhotonModel IN101T -Basic Integrating Nephelometer

SHARE

AirPhoton IN101T is our basic Integrating Nephelometer. It is generally used for simple operations such as determing the bulk properties of aerosols including the overall amount and size of the particles. This instrument is highly valued for its accuracy and reliability, providing essential data for environmental monitoring and research.

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.

We produce several different models of nephelometers. Our more advanced models allow for data collection at multiple size cuts. When combined with the GRASP retrieval algorithm these instruments provide a wealth of information beyond what is possible with a standard nephelometer.

Our nephelometers offer described on this website can be used with our communications module allowing for internet or cell network control and monitoring of the instrument. Our philosophy is to collect and measure particles under ambient conditions. Yet, we can, at additional cost and upon request, provide a nafion tube system to dry the aerosols.

  • The IN101T can provide forward and back scatter measurements, three wavelenghts and high-speed fan.

We suggest the IN101T 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 long inlet tubes.
