  • Thermoanemometers with fast and accurate airflow measurements
  • Displays up to three measurements simultaneously
  • Available with manual or continuous data logging
  • Logs up to 12,700 samples and 100 test IDs
These meters simultaneously measure and datalog several ventilation parameters using a single probe with multiple sensors. Great for cleanroom filtration airflow measurements — they automatically calculate volumetric flow rate for round, square, and rectangular areas. All models measure velocity, temperature and calculate flow.Straight probe included. Auto shut-off preserves battery life, and a low battery indicator alerts user of battery condition.

  • Q:

    I need to measure velocity of air in side a refrigerator at 16 different point simultaneously while the refrigerator is in operation. Can you recommend a product for that.

      A:

      This only can take a measurement in one location at a time.

  • Q:

    The website says this model supports both manual or continuous data logging. Is that true?

      A:

      This product does not allow continuous, live data logging standard, however the 10271-27 does have the capability for continuous datalogging. Another option would be using a secondary software to access the data, such as Labview.

      Answered on 5/22/2013 by Jack from Technical Support
    • A:

      Yes - this is absolutely true I do it all the time.

  • Q:

    I would like to datalog continuously for a week with this device, at the frequency of 1 measurement per minute (total 10,080 data points). I see the specs say the device can store 12,700+ data points. Can they be collected over a week or is there a maximum monitoring period?

    • STAFF EXPERT

      A:

      Item 10271-25 does not have continuous logging. Samples can only be logged over a 1-30 second sampling interval. Item 10271-27 now has continuous logging (introduced with firmware v2.0). and will be able to take 1 minute samples over a one week period. The data storage capability on the instrument is 12,700+ samples.

  • Q:

    I would like to insert the probe into the small duct to measure the velocity.
    But, ducts only have 1cm or 2cm height.
    Does this Velocity Meter suit for my duct?
    What is the length from the probe top to the end of the small hole?
    Asked on 2/8/2011 by YAO from College Station Texas

    1 answer

    • STAFF EXPERT

      A:

      The duct range is 1 to 635 cm. From the top of the probe to the bottom of the hot wire hole is approximately 3 cm.

  • Q:

    I'm looking for a hand held unit to cross check our TSI 8455-12 Hot Wire Anemometers that are installed in our wind tunner.
    What unit would you recommend?
    Asked on 8/16/2010 by Mark from Missoula Montana

    1 answer

    • STAFF EXPERT

      A:

      This product is capable of validating the data from other Anemometers, however you should verify that this product is appropriate for your specific application.

  • Q:

    I need to take 20 velocity readings, 1 second apart. I then need the average of the 20 readings. Can this meter give me the average?
    Asked on 12/6/2009 by Balance King from Franklin township

    1 answer

    • STAFF EXPERT

      A:

      The data can be downloaded to a PC to be analyzed, but the unit itself does not have the functionality to calculate an average.

    • Low-velocity Measurements

    Comments about TSI 9535 VelociCalc Air Velocity Meter with Straight Probe, no Humidity Sensor:

    After receiving two defective anemometers from a different manufacturer, I decided to spend a bit more and buy this TSI model. I was very pleased with how easy it is to use and how low of a velocity it is able to measure. I recently purchased a second one as a back-up in case we damage this one.

    Sales associate was very courteous. Assured me the calibration would not be more than 6 months old on the new device.
