The TSI 964 Thermoanemometer Straight Probe is a plug-in probe for the VelociCalc 9565-P meter, designed to measure air velocity, temperature, and humidity in one tool. It’s ideal for duct traverses, fume hood face velocity checks, filter testing, cleanroom verification, and HVAC commissioning.
With a velocity range of 0 to 9,999 ft/min (0–50 m/s), temperature from 14 to 140°F (-10 to 60°C), and humidity from 5 to 95% RH, the 964 delivers accurate, repeatable results. Its straight, telescoping design allows easy placement across ducts and diffusers.
