VT110- VT115 Hot Wire Thermo Anemometer
- VT 110 / 115 anemometer is perfect for measuring airflow, air velocity and temperature with its hot wire probe technology.
- Ideal for HVAC Engineers in the measurement of ventilation or heating systems.
- Hot wire technology is capable of detecting low velocity air flow with great precision.
In heating, ventilation and air conditioning (HVAC) systems, precise airflow and temperature measurements are critical for efficiency, comfort, and regulatory compliance. One of the most reliable tools for capturing such data in HVAC ducts and vents is the hot wire probe anemometer. This instrument is especially valued for its sensitivity to low air velocities, accuracy in confined spaces, and ability to measure multiple parameters simultaneously.

Applications in HVAC
- Duct airflow balancing: Ensuring equal air distribution to different zones.
- Vent performance testing: Measuring velocity and temperature directly at diffusers or grilles.
- Filter performance monitoring: Detecting airflow reduction due to clogged filters.
- Energy audits and diagnostics: Identifying inefficiencies in airflow and temperature delivery.
- Cleanroom or laboratory environments: Monitoring laminar flow systems with precision.
