  • Indoor Air Quality

    TSI offers a line of indoor air quality instruments designed to accurately and reliably measure a variety of parameters important in monitoring and maintaining occupant thermal comfort while helping to assure healthy indoor environments. Typical air measurements include temperature, humidity (%RH, wet-bulb, dewpoint), outdoor air calculations, carbon dioxide, carbon monoxide and airborne particles. These instruments are optimized for easy operation yet still provide a full range of advanced cap

  • Q-TRAK Plus  - Indoor Air Quality Monitor

    Q-TRAK Plus - Indoor Air Quality Monitor

    TSI offers two hand-held Q-TRAK Plus IAQ Monitors. The Q-TRAK Plus Model 8552 monitor simultaneously measures CO2, temperature and humidity, all within a single probe. The Q-TRAK Plus Model 8554 adds CO. These easy-to-use, air quality instruments provide real-time measurements and can log data unattended over an extended period of time. Advanced logging modes allow you to program the start time, test duration, sampling frequency and other...

  • AEROTRAK - Model 9000 - Nanoparticle Aerosol Monitor

    AEROTRAK - Model 9000 - Nanoparticle Aerosol Monitor

    The AEROTRAK™ 9000 Nanoparticle Aerosol Monitor indicates the surface area of nanoparticle aerosols that deposit in the lung, corresponding to the ICRP lung deposition curves for the tracheobronchial (TB) and alveolar (A) regions of the human respiratory tract. The AEROTRAK™ 9000 monitor is a portable, battery-operated diffusion charger + electrometer with real-time surface area concentration readout and data logging capability.

    AEROTRAK - Handheld Particle Counters

    The AEROTRAK™ Optical Particle Counter is an addition to TSI’s full line of real-time particle measuring instruments including photometers for mass concentration, condensation particle counters for ultrafine particles and diffusion charging with electrometer signal for surface area measurement. Typical applications include cleanroom monitoring, research, exposure assessment, indoor air quality, filter testing, clearance testing, quality...

  • IAQ-CALC CO2 Meter

    IAQ-CALC CO2 Meter

    TSI's Model 8732 IAQ-CALC™ Meter is a cost-effective CO2 meter for investigating and monitoring building air quality and checking ventilation. The sampling function records multiple point measurements, and an optional portable printer provides hard copy documentation.

  • IAQ-CALC IAQ Meters

    IAQ-CALC IAQ Meters

    TSI's IAQ-CALC™ Meters are exceptional indoor air quality instruments for investigating and monitoring building air quality. These IAQ instruments simultaneously measure and data log multiple parameters to monitor indoor air quality conditions. The Model 8760 measures CO2, temperature, humidity, and calculates dew point, wet bulb temperature, absolute humidity, humidity ratio and % outside air. The Model 8762 IAQ meter adds CO.

  • Nanoparticle Surface Area Monitor

    Nanoparticle Surface Area Monitor

    The Model 3550 Nanoparticle Surface Area Monitor measures the human lung-deposited surface area of particles (reported as µm2/cm3) corresponding to tracheobronchial (TB) and alveolar (A) regions of the lung. The Model 3550 provides a simple and fast solution for measuring the surface area equivalent dose in the lung. The Model 3550 is an important instrument for research in the fields of inhalation toxicology, health effects and epidemiology, and for...

  • P-TRAK - Ultrafine Particle Counter

    P-TRAK - Ultrafine Particle Counter

    The TSI's P-TRAK® Ultrafine Particle Counter (UPC) is a totally new approach to eliminating IAQ problems. This portable instrument detects and counts ultrafine or nanoparticles (smaller than 1 micrometer in aerodynamic diameter) that often accompany or signal the presence of a pollutant that is the root cause of complaints. It is now being used to track down some of the most difficult IAQ problems imaginable.

  • TH-CALC - Thermohygrometers

    TH-CALC - Thermohygrometers

    TSI's TH-CALC™ Thermohygrometers are excellent hand-held diagnostic instruments for measuring temperature and humidity. The meters measure temperature and humidity, and also calculate dew point.
