Number 1 in Versatility

The SOLAIR 5100 is the most versatile particle counter on the market today.

Whether you are certifying your cleanroom to ISO standards, performing routing testing, counting particles in your compressed gas lines, scanning your HEPA filters for leaks, challenge testing your HEPA filters, or measuring environmental parameters such as TRH, DP, AV the SOLAIR 5100 portable particle counter is the right instrument to get the job done.

Cleanroom Certification

  • Whether you are certifying to current ISO 146644 standards, EU GMP Annex 1, or Federal Standards 209E, the SOLAIR 5100 has you covered with its certification report wizard.

Routine Testing

  • Routine testing is a breeze with the intuitive interface, zoom screen, and onboard sample recipes.


  • With beep and concentration sample modes the SOLAIR 5100 will simplify the identification of particle sources within your cleanroom.

Compressed Gas Testing

  • The SOLAIR 5100 can be used to test for particle counts in compressed air by utilizing a high-pressure diffuser or high-pressure controller.  Particles can be tested down to 0.5 microns.

HEPA Filter Scanning

  • The scanning of HEPA filters is a critical step to ensure the integrity of the HEPA filter and the overall cleanliness of the cleanroom.  The ScanAir attachment from Lighthouse makes filter scanning an easier operation.

HEPA Filter Challenge Testing

  • Monitoring of other environmental parameters such as Temp, Humidity, Differential Pressure or Air Velocity.

Other Environmental Sampling

  • The SOLAIR 5100 can record data from up to 4 environmental sensors that plug into and are powered by the SOLAIR 5100.  Data is recorded into the 3,000 record data buffer and can be downloaded along with the particle count data to your computer of via USB key.

Ease of Use

Spend less time configuring your particle counter and more time counting particles.  The SOLAIR 5100 features one of the industry’s best and easy to use touch screen interfaces (UI). With ICON-driven menus, concise layout, and enhanced responsiveness, sample configuration is a breeze.

The intuitive interface reduces learning uptime for new users and simplifies the writing of SOP’s for operation.

For cleanroom certification, the SOLAIR 5100 has an integrated report wizard that makes cleanroom certification a breeze.  Once the basic sample parameters are input the wizard will prompt the end-user to move to the next sample location, this helps to ensure no sample locations are missed.

The configurable recipe database can store up to 50 recipes for sampling and reports.  These recipes reduce operator configuration errors as well as setup time.

Lighter is better and the SOLAIR 5100 particle counter is one of the lightest particle counters on the market at only 12 lbs. without battery and 13.4 with a battery.

The SOLAIR 5100 can be powered via onboard battery or plugged directly into a power outlet for extended use.   With the fastest battery recharge time of any portable on the market, the SOLAIR 5100 offers unrivaled uptime.

Data from the SOLAIR 5100 can be downloaded directly to a standalone software package or a real-time monitoring system from Lighthouse.

Flexible communications with these instruments are made possible by the integrated Ethernet, RS-485, USB, and USB flash drive interfaces.


The SOLAIR 5100 incorporates our extreme life laser diode technology sensor to produce the industry’s longest laser diode life of 20+ year MTTF (based on continuous 24/7 operation).

The vacuum system within the SOLAIR 5100 was designed with closed-loop feedback to ensure accurate sample volumes.  The vacuum pump was designed and built by Lighthouse to ensure long-term reliability.

The SOLAIR 5100 is designed, manufactured, and calibrated to ISO 21501-4 to ensure particle-counting accuracy.

The SOLAIR 5100 can store up to 3,000 records of particle count data from up to 8 particle channels and the configurable recipe database can store up to 50 recipes for sampling and reports.  All data can be quickly and reliably transferred to a computer, a Facility Monitoring System or a Building Automation System.  Secure data transfer (per 21 CFR Part 11) to a USB flash drive can be accomplished by using the Lighthouse secure data transfer feature and LMS Express software.
