The 9535

The Model 9535 VelociCalc® Air Velocity Meter is a versatile instrument for HVAC professionals. Owning one of these meters is like having multiple meters in one instrument. The 9535 can simultaneously measure and log several ventilation variables, including velocity and temperature, using a single probe with multiple sensors. The instrument can also perform flow calculations. Included with the 9535 is one telescopic straight probe, so you can easily reach ceilings and other hard to reach areas without a ladder.

• Simple intuitive operation
• Industry leading accuracy
• Simultaneously measure temperature and velocity
• Displays up to three measurements simultaneously
• Data log 12,700+ samples and 100 test ID's

Accurate

TSI meters, including the Model 9535, provide substantially better accuracy at low flows and throughout a wide dynamic range than competitive instruments. This gives users improved performance in critical applications, so results are always reliable. Customers and distributors agree that TSI instruments allow for best-in-class data management and reporting. User generated reports from TSI instruments help you solve problems, saving time and money.

Intuitive

The 9535 is simple to operate. With it, users can optimize indoor environments and store data internally for later review. The unit is very rugged and will stand up to daily use and abuse. Plus, since the 9535 is a multi-parameter instrument, it will save you money in the long run because you don’t need to buy a probe for each measurement. If you do need additional probes, the 9535 will accept them with no additional programming or calibration.
