Velocity, Volume and Temperature
The ATP ET-935 is a remote vane thermo-anemometer designed to measure air velocity and air temperature quickly and accurately. Featuring a 75 mm vane connected via a 1.5 metre coiled cable with secure plug, it is ideally suited to ventilation surveys, air conditioning, heating applications, and environmental monitoring where reliable airflow data is essential.
The instrument measures air velocity across a wide range from 0.4 to 30 m/sec with fine resolution and supports multiple units, including m/sec, ft/min, mph, km/hr, and knots. In addition to velocity, the ATP ET-935 calculates airflow volume in both m³/min (CMM) and ft³/min (CFM), allowing users to assess system performance efficiently without manual calculations.
Temperature measurement is fully integrated, with readings available in both °C and °F. The dual display allows air velocity and temperature to be viewed simultaneously, improving efficiency during surveys and inspections. Readings are presented on a large 35 mm high-contrast LCD display with backlight and clear function indicators, ensuring excellent visibility even in low-light environments. A 16-segment bargraph provides an instant visual reference for changes in airflow.
The ATP ET-935 includes practical data handling features to support accurate field measurements. Data hold and minimum/maximum recording functions capture fluctuating airflow and temperature values, while the averaging function, based on the last 10 seconds, helps stabilise readings in turbulent air conditions.
Designed for regular professional use, the ATP ET-935 also incorporates a low battery indicator and automatic power-off after 15 minutes of inactivity to help conserve battery life. Supplied with a soft carry case and battery, the instrument is ready for immediate use and easy transport between job sites.
Why the ATP ET-935 Belongs in Every Professional Toolkit
A professional toolkit should include instruments that deliver accuracy, versatility, and confidence in real-world environments, and the ATP ET-935 meets those requirements with ease. Its remote vane design allows technicians to take precise measurements in confined or awkward locations such as ductwork, grilles, and ceiling diffusers, without compromising comfort or safety.
Measurement flexibility is a key advantage of the ATP ET-935. With support for multiple velocity and volume units, it adapts easily to different industries, reporting standards, and site requirements. The ability to measure both airflow and temperature simultaneously saves time during inspections and reduces the risk of recording errors.
The combination of a clear dual display, visual bargraph, and intelligent averaging function ensures dependable readings during ventilation surveys and HVAC balancing tasks. Together with its robust feature set and user-friendly operation, the ATP ET-935 enables engineers and technicians to work efficiently, make informed decisions, and deliver consistent, high-quality results.
