| VelociCalc Thermal Anemometers |
| Models 9535, 9535A, 9545 and 9545A |
| Model 9545 |
| Features and Benefits |
| • Simple to operate • Accurate air velocity measurement • Simultaneously measure temperature and velocity • Displays up to three measurements simultaneously • Measures humidity (Model 9545 and 9545-A) • Calculates volumetric flow, and actual/standard velocity • Data log 12,700+ samples and 100 test IDs • LogDat2TM downloading software included • Articulated probe versions available (9535-A and 9545-A) Applications • HVAC system performance • Commissioning • Simple to operate • Plant maintenance • Critical environment certification • Duct traverses |
| The Models 9535 and 9545
thermal anemometers are like having multiple meters—for
the price of just one. These meters simultaneously measure and data log
several ventilation parameters using a single probe with multiple sensors.
Both models measure velocity, temperature and calculate flow. The Model
9545 also measures relative humidity, and calculates dew point, and wet
bulb temperature. Models 9535 and 9545 have telescopic straight probes;
Models 9535-A and 9545-A have telescopic articulated probes. |
